Frequently Asked Questions
Thin Section Bearings: Highly precise and compact, these are ideal for applications with strict space and weight limitations, such as aerospace, medical equipment, and robotics.
Crossed Roller Bearings: Featuring rollers arranged at right angles, these bearings can handle loads from all directions simultaneously. They are perfect for industrial robots, machine tools, and precision rotary stages.
Full Ceramic Bearings: Made entirely of ceramic materials (like Zirconia or Silicon Nitride). They are highly resistant to extreme heat, highly corrosive chemicals, and are completely non-magnetic and non-conductive.
Hybrid Ceramic Bearings: These feature standard steel inner and outer rings, but use ceramic balls. They are lighter, generate less friction, can achieve much higher speeds than all-steel bearings, and are excellent for preventing electrical arcing in electric motors.
Slewing Bearings (Slewing Rings): Large-diameter bearings designed to support heavy, complex loads (axial, radial, and overturning moments). Commonly used in cranes, excavators, and wind turbines.
Deep Groove Ball Bearings: The most common type, ideal for versatile, high-speed applications.
Angular Contact Ball Bearings: Designed to support combined radial and axial loads.
Thrust Ball Bearings: Built specifically to handle high axial (thrust) loads.
Self-Aligning Ball Bearings: Perfect for applications where shaft misalignment might occur.
Tapered Roller Bearings: Ideal for handling heavy combined (radial and thrust) loads, commonly used in automotive and heavy machinery.
Cylindrical Roller Bearings: Excellent for high radial loads and high speeds.
Spherical Roller Bearings: Designed for heavy loads and capable of compensating for misalignment.
Needle Roller Bearings: Compact bearings with a high load capacity, perfect for spaces with limited radial clearance.
Rotary Table Bearings: High-rigidity, high-precision bearings built specifically for machine tools, indexing tables, and precision measuring systems.
Pillow Block Bearings: Ready-to-mount units combining a housing and an insert bearing, typically used to provide easy, reliable shaft support in standard industrial applications.
Split Plummer Block Housings: Heavy-duty, two-piece housings that allow for easy bearing installation, inspection, and maintenance. They are frequently used with spherical roller bearings in mining, conveyors, and heavy industry.
Adapter Sleeves: Essential mounting accessories used to secure bearings with a tapered bore onto a straight, cylindrical shaft. They are easy to install and require no additional location on the shaft.
The quickest way is to provide us with the exact part number (e.g., 6204-2RS) and your preferred brand (e.g., SKF, NSK, Timken, or a budget alternative). If you have this, simply send it over along with your required quantity!
If you don’t have a part number, we can identify the bearing if you provide the following three dimensions (preferably in millimeters):
Inner Diameter (ID or Bore): The size of the hole in the middle.
Outer Diameter (OD): The total width of the bearing from the outside edges.
Width (W): The thickness of the bearing.
Please let us know the design type if you know it. Common types include Deep Groove Ball Bearings, Tapered Roller Bearings, Thrust Bearings, Spherical Roller Bearings, or Pillow Blocks. If you aren’t sure, a photo of your current bearing is incredibly helpful!
Bearings come with different closure types to keep grease in and dirt out. Please specify if you need:
Open: No seals or shields.
ZZ / 2Z: Metal shields on both sides (best for dusty environments).
2RS / DDU: Rubber seals on both sides (best for wet or highly contaminated environments).
Our standard bearings are made from premium chrome steel (Gcr15), which is suitable for most applications. However, if your application requires it, please specify if you need Stainless Steel (for rust resistance), Ceramic (for high speeds/temperatures), or Plastic.
Knowing your application helps us ensure you get the right product. Please let us know if the bearing will be exposed to:
Extreme high or low temperatures
Exceptionally high speeds (RPM)
Heavy vibrations or extreme loads
Chemicals, water, or food-grade environments (which require special grease)
Any specific clearance or tolerance requirements (e.g., C3 clearance, ABEC-5 precision).
Bearing prices are highly dependent on volume. Please let us know your immediate order quantity, as well as your Estimated Annual Usage (EAU) if you are looking for a long-term supply. Higher quantities generally result in a lower cost per unit.
We supply a wide range of premium and standard bearing brands to meet your specific needs and budget. Our network includes top-tier global brands such as [List Brands, e.g., SKF, FAG, INA, Timken, NSK, NTN, KOYO], as well as high-quality, cost-effective alternative brands.
We understand the dangers of counterfeit bearings in the industrial market. We source our products strictly through authorized channels, direct manufacturers, and vetted, trusted global distributors. We can provide Certificates of Origin (COO) and material certificates upon request.
If your preferred brand has a long lead time or is too expensive, our technical team can cross-reference the part number and recommend a direct, drop-in replacement from another reputable brand that meets the exact same specifications.
Our team provides application engineering support. If you provide us with your operating conditions (load, speed, temperature, environment, and shaft size), we can recommend the optimal bearing type, clearance, and seal configuration for maximum lifespan and performance.
we export bearings worldwide. We work with major freight forwarders (DHL, FedEx, UPS, air freight, and sea freight) to ensure fast, safe, and cost-effective delivery to your facility, no matter where you are located.
We can provide customized packaging, barcoding, or labeling to match your inventory system.
We can customize nearly every aspect of a bearing to suit your application, including:
Dimensions: Non-standard inner diameters (bore), outer diameters, and widths.
Materials: Chrome steel, stainless steel, ceramic, plastic, or specialized high-temperature alloys.
Seals & Shields: Custom rubber seals (RS, 2RS), metal shields (Z, ZZ), or Teflon seals.
Lubrication: Specific greases or oils (e.g., food-grade, high-temperature, or vacuum-compatible lubricants).
Internal Clearance & Tolerance: Custom radial clearances (e.g., C2, C3, C4, C5) and precision classes (ABEC-1 through ABEC-7 / P0 through P4).
Cages/Retainers: Steel, brass, nylon, or PEEK cages.
Whether you need a slight modification to a standard bearing (like a special grease) or a completely new, tailor-made bearing assembly designed from scratch, our engineering team can manufacture it.
The MOQ depends on the size and complexity of the bearing.
For large or highly specialized bearings, the MOQ can be as low as [1 to 10] pieces.
For miniature or small standard-sized custom bearings, the MOQ may range from [1,000 to 5,000] pieces to justify the setup costs. Please contact us with your requirements, and we will provide a specific MOQ.
There are widely applications our bearings are used like: humanoid robotic, industrial robotic, motor, metallurgy, rail transit, fitness equipment, hardware tools, CNC machine tools, CT machinery, and special applications for high speed, high temperature, or very low temperature, corrosion environment and so on.
It depends, if standard modals with stocking or regular production, we can supply samples.
Other wise it needs MOQ. Some custom made products with even a bit higher MOQ because most times it related to open mould and the material needs buy a lot.
We offer free samples for most of our standard, low-cost bearings. However, for high-value bearings (e.g., large-size bearings, high-precision spindle bearings) or custom-made items, we do charge a sample fee.
Our expert team can help you navigate factors like load capacity, speed, and environmental conditions to select the ideal bearing solution. Discover personalized guidance for your application needs.

Testimonials
Our inquiry initially involved custom-made slewing bearings, thin section ball bearings, and a stainless steel pipe. Throughout the process, ZMS sales and technicians demonstrated exceptional patience and professionalism as they accommodated our requests for drawing changes, which occurred multiple times. Despite the lengthy duration of over six months, the outcome was a resounding success. We received precisely what we had envisioned, and we are eager to continue collaborating with ZMS in the future, particularly in larger quantities of this specific model.

We have been purchasing thin section ball bearings 68&69 series from China, while one time the customer was not satisfy with sealing of our already supplier. We tried to get in touch with ZMS that they sent letters to us a lot times before. And soon we get the full list quotation of 68&69 series. Although the price is much higher than our already supplier, we tried the sample of 6824 2RS and compared the quality with SKF the same series for customer. The customer can accept the quality and the price which is a big releif for us. Although the quality can’t compared with top famous brand. But we list them as Supra in our product for customers want to buy high quality bearings from China.
Corina Findling
We looked for one ball bearing 34052057 and ZMS gave a fast quotation based on that. After comparation, we thought the price and bearing services is suit for us. And we concern about material analyse, so we need material certificate. They also gave as the request. As the communication goes on, ZMS supply the drawing for our technician checking, about the clearance, they mentioned there are C0, C2, C3 clearance. We choose C3 clearance, but while put the value on the drawing, our technician still think the clearance should a bit lower than C3. So they changed the clearance as our requirements on the drawing. Other things goes very soomth.
Razmi
We inquired thin section bearing 10.0000×10.5000×0.2500 from ZMS while first we got products from an UK company that a dealer of kaydon series, while the price keep up and the extremly long delivery more than 22 weeks. We seeked for alternative. The quotation is fast and delivery is short to 10days. After checking the structure of X four point contact instead of deep groove ball bearing and also packing information as they supplied of photo vacuum packaging.The thin bearings worked well on our machinery. We thought the price with performance was suit for us. We would keep working with ZMS on other bearing projects.
Sadik DANKAZ
We demand of ship crankshaft slide bushings, customized, to be produced. After the soon feedback, we sent drawing for ZMS reference. This is half and half bearing with very thin section and with alloy material. It just within ZMS products series and they gave the quotation soon. During the process we want to change the alloy material, it seems not workable, they said the original material was regular for them. So we agreed on the orignal material. Again we changed the ID size from 165 +0,10;+0,12 to 164, 9mm. We revised the drawing and made the payment. The production is fast within 15 days that is out of our expection.
Veselin Zahov
We were looking for a thin section bearing which has the footprint of 360x376x8mm x point type bearing.We concerned of the rpm of the bearing and also we asked for the data sheet for reference. ZMS checked the size and confirmed the modal to be kaydon series K36008XP0 and they need MOQ 10 pcs. Production time need 50days. After everthing negoniated well, we paid the deposit. There was one thing we didn’t mentioned the grease, that need to be suit for vacuum environment. But at that time the Fedex shipment had on the way. Then we could add the vacumm grease when they arrived.
