Thin section bearings

We have been manufacturing thin section bearings more than 30 years with export nearly 15 years.

We supply thin ball bearings 67& 68 &69 series, thin section bearings and slim bearings of Kaydon series and ultra-thin bearings.

At the same time, we can produce custom thin section bearings by customer request, for example, special structures, special materials, lubricants and clearance.

FAQ of thin section bearings

ZMS produces deep groove ball bearings with thin wall like 67, 68 and 69 series.

Kaydon series thin section bearings metric and inch series.

Thin ball bearings for bikes.

Custom thin section bearings.

We supply high quality thin section bearings in China to other countries in the world 15 years.

We can make sure the bearings with better roundness and better runout.

For micro and small thin section bearings, we can make the precision P5 ZV3

For medium size thin section bearings, we can make precision P5 ZV2

For thin section bearings actual there is no vivid requirements about noise level in international or China standards, but we assure that we control it as much as possible.

Normally P0,Z1 will be ok for customers, if you really needs bearings in very precision, please contact us in detail discuss.

ZMS can supply drawings based on standard modals on the request of customer. Custom make thin section bearings, we can make by customers drawing or we can design drawings by customer requirements.

We can supply sample for quality checking if the modal under 6820 and 6920 for free 1pc. Kaydon series thin section bearings, and large size thin ball bearings, we can sell at cost price for customer for quality checking.

  1. Appearance inspection

Appearance inspection is the first step in bearing quality inspection and can be inspected with the naked eye or microscope. Mainly check appearance defects, surface quality, size and geometry, etc. Appearance defects include cracks, slag inclusions, bubbles, burrs, etc. Surface quality includes smoothness and surface roughness. These two indicators have a great influence on the service life of bearings.

  1. Size measurement

The accurate measurement of bearing dimensions is the core content of bearing inspection. There are two methods for measuring bearing dimensions: direct and indirect. The direct method is to use high-precision measuring tools, such as micrometers, vernier calipers, micrometers, average meters and three-dimensional coordinate measuring instruments. The indirect method is to obtain dimensional information through the performance parameters of the bearing, such as the bearing’s load-bearing capacity, rotation speed, friction coefficient, noise level and motion accuracy, etc.

  1. Hardness test

Hardness testing is an important method of measuring the internal quality of bearings. The hardness test can check the surface hardness, harden hardness, cut hardness and hardness uniformity of the bearing. Currently commonly used hardness testing methods include rock motor, Vickers hardness tester, Brinell hardness tester and Rockwell hardness tester.

  1. Noise detection

Noise detection is one of the important methods to inspect the internal quality of bearings. The bearing structure is complex and the sources of internal noise are complex, requiring the use of sophisticated testing instruments. Commonly used test equipment for noise detection include audio and electronic spectrum analyzers, signal generators, power amplifiers, vibration sensors, etc.

For micro and small thin section bearings, we normally use: plastic bottle+ carton+ pallet

For medium size thin section bearings: Kraft paper+ carton+pallet

For large size: wrapping+woodencase

We can supply customized packing by customer requirements, but it will normally need the quantity fullfil.

We can accept customer sending packing material to packing.

Individual white box + label

All packing we need to discuss on the business process, so that we can quote by requirements.

TT mostly.

LC and other payment need to discuss.

FOB,CIF mostly.

DDP,DAP and other terms need to discuss.

Stocking: We stock most standard modals for thin section bearings so for small quantity we normally can supply fast.

Workpieces: We prepare materials for some popular modals or old customer regular order modals, if we don’t have stocking, we can fast finish in 10-30days.

Production:Mass production of large quantity or some modals we don’t have stocking also don’t have material, we need to order material then start produce step by step this will cost 60-70days.

Normally a week in advance when we finish the production, we shall contact customer and tell them the gross weight and volume to get the permission of booking space.

And the forwarder will give us delivery notice that will mark the last date of entry warehouse.

We delivery goods to the entry warehouse and it takes 2-3working days for custom clearance in China. Then when everything goes smoothly the boat will shipping as the shipping date.

Commercial Invoice, Packing list, BL and certificate of original if needed.

Other special documents, we need to check first.

Quality assurance in one year. Any times it is related to quality problems, please get back to us first time, if it is our problem, we shall responsible to the last.

Quality Assurance

We test thin section bearings from raw material to the finished goods. By machinery test also together hand testing, feeling and watching.

Equipped with professional inspectors to walk around by random checking by percentage. And also have special test persons 100% test for the workpieces and finished bearings inspection.

By 100% heart on concentrating the bearings production, inspection, packing, delivery, document making and communication during the whole process.
