Deep Groove Ball Bearings 6300 Series
Single row deep groove ball bearing housings are the most widely used bearing types:
1. Basic design of open bearing
2. Sealed bearings
3. ICOS oil-sealed bearing unit
4. Bearings with snap grooves, with or without snap rings

Spherical Roller Bearings 213xx Series
This bearing type has a solid inner ring, which runs on two rows of symmetrical rollers in a solid outer ring. The outer ring has a concave, spherical raceway. This design compensates for any alignment errors and shaft deflections. Spherical roller bearings can withstand particularly high radial loads. Additionally, they can accommodate axial forces in both directions. These bearings are used in elevators, textile machines, food processing machines, cranes etc.
Deep Groove Ball Bearings 6200 Series
Single row deep groove ball bearing is the most representative structure of rolling bearings and has a wide range of uses. The raceways located on the inner ring and the outer ring have an arc cross section with a radius slightly larger than the radius of the rolling ball. In addition to bearing radial load, it can also bear axial load in two directions. Low friction torque, most suitable for applications requiring high speed rotation, low noise and low vibration. This kind of bearing, in addition to the open type, also has a bearing with a steel plate dust cover, a bearing with a rubber seal, or a bearing with a snap ring attached to the outer diameter of the outer ring. Generally, steel stamping cages are used. Mainly applicable cage: steel stamping cage (wave shape, crown shape...single row; S shape...double row)
Flange bearings are among the ultra-small bore miniature bearings, which can be divided into ZZ steel plate bearing dust cover series, RS rubber bearing sealing ring series, flange plate series, stainless steel series, ceramic ball series, etc. The miniature ball bearings have a wide range of uses. Suitable for products requiring high-speed rotation, low friction torque, low vibration and low noise.
Needle Roller Bearings RNA, NK Type
RNA, NK type needle roller bearings, this type of bearing has no inner ring, it is suitable for the support structure with limited radial installation size, and the journal matched with the bearing is directly used as the rolling surface. As the shaft of the raceway surface, the hardware must be hardened and ground, and only when it is processed to the appropriate size and shape accuracy, the entire set of needle roller bearings can have a high life and running accuracy. At the same time, since there is no inner ring, the diameter of the shaft can also be appropriately enlarged, thereby increasing the rigidity.
Roll Neck Bearings for Rolling Mill
Four-row tapered roller bearings and four-row cylindrical roller bearings used for rolling-mill roll necks are easy to service and check.
And mainly characterized by high radial bearing capacity, small section size and high limit speed. The bearing has good rigidity and high manufacturing precision.
Also, they are designed for high speed to satisfy the demand for fast rolling.
