NSK/KOYO Spherical Roller Bearing (22313K)
Spherical roller bearings are inherently self-aligning and very robust.
There are two rows of rollers which make the bearings able to carry heavy loads. The spherical roller bearings mainly includes CC, CA, CAE, MB and E type. LHZ can provide a wide range of sizes of several ISO Dimension Series and also includes special designs, for example, for vibrating screens and other applications. Special bearings can also be customized as required based on the standard bearings.
Gaoyuan Bearing Co., Ltd have a large number stock, include: Deep groove bearing, Cylindrical roller bearing, Self-aligning bearing, Self-aligning roller bearing, Needle bearing,
Angular-contact ball bearing, Tapered roller bearing, Thrust ball bearing,
Thrust self-aligning roller bearing, Thrust cylindrical roller bearing, Liner bearing, Liner guides,
Articulated bearing and so on. Our products use for industry, machinery, rolling mill, textile process, railway,
Metallurgy and mine, and we can provide complement for them, Technical support at any time.
The advantage
1). Raw Material: Specified high quality GCR15
2). Advanced digital turning, grinding machines and experienced workers guarantee the precision and quality.
3). QC: Workers do three and check one of them, according to the operation card attached on the machine.
4). Automatic demagnetization, cleaning& anti-rust machine to ensure the cleanliness of the product.
5). Quality Control: QC inspect 4times/day at random, 100%full inspection before assembling &shiped.
6). Professional management system and team, tidy workshop environment to lead a good mood to every worker.

| Tolerance |
spherical roller beairngs with P0, P6 and P5 precision grades according to customers demands.
All tolerance values conform to GB307.1 standard. |
| Radial Clearance |
spherical roller bearings with C2,C0, C3, C4 and C5 clearances, which all conform to the GB4604 standard. |
| C3 clearance is taken as the standard clearance for tapered bore spherical roller bearings. |
| C4 clearance of spherical roller bearings applied to vibration screen. |
| Cage |
Normally, these bearings can be divided into CA and C structure.
CA structured spherical roller bearings adopets solid cages with the material brass, bronze, nodular cast iron, or steel.
But C structured spherical roller bearings normally adorpts pressed steel cages. |
