Adapter Sleeve
Adapter sleeves are the most commonly used component for locating bearings with tapered bores on cylindrical shafts. They can be used on both smooth and stepped shafts.
Adapter sleeves consist of a bushing, lock nut, and lock washer (or locking clip). Adapter sleeves with lock nut and lock washer are interchangeable only as a complete set; parts from different sources are not interchangeable. Adapter sleeves are easy to install and do not require additional fixings to the shaft.

-
Cylindrical Roller Bearings
The rollers of cylindrical roller bearings are usually guided by two ribs of a bearing ring. The cage, rollers and guide ring form an assembly that can be separated from another bearing ring and is a separable bearing. It is more convenient to install bearings and magnetic fields, especially when the interference fit between the inner and outer rings, the shaft and the shell is required. This type of bearing is generally only used to bear radial load. Only single row bearings with ribs on both the inner and outer rings can bear smaller axial load or large axial load intermittent. At ZMS, we specialize in providing high-quality cylindrical roller bearings. As a leading supplier in the industry, we offer a comprehensive selection of cylindrical roller bearings, including single-row, double-row, and four-row designs, engineered for both industrial and automotive applications.

Deep Groove Ball Bearing
Deep groove ball bearings have a simple structure and are easy to use. They are the type of bearings with the largest production batches and the most widely used. It is mainly used to bear radial load and can also bear certain axial load. When the radial clearance of the bearing increases, it has the function of an angular contact bearing and can withstand larger axial loads.
Compared with other types of bearings of the same size, this type of bearing has a small friction factor and a high limit speed.

Pillow Block Bearings
Pillow block bearing is a bearing unit that combines a spherical ball bearing and a bearing housing with various shapes. Bearing seat is generally cast molding. Common seats are vertical seat (P), square seat (F), convex square seat (FS), convex circular seat (FC), diamond seat (FL), ring seat (C), slide block seat, etc. (T).
Pillow block bearing can be directly installed on the main body of the mechanical device through a few bolts.
This type of bearing has a certain degree of alignment in design, is easy to install, has a dual-structure sealing device, and can work in harsh environments. The bearing seat is generally cast.
ZMS has been supplying high quality mounted bearings for 15 years.And we can custom made pillow block bearings by customer requirements.
