Timken NSK NTN Koyo NACHI IKO Deep Groove Ball Bearing Taper Roller Bearing Spherical Roller Bearing Cylindrical Angular Contact Needle Bearing 21309 Bearing

Self-aligning roller bearings have double-row rollers, the outer ring has a common spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious structure makes it have self-aligning performance, so it is not easy to be affected by the angle error or shaft bending of the shaft and the bearing housing, and is suitable for installation errors or shaft deflection that cause angle errors. In addition to bearing radial loads, the bearing can also bear axial loads acting in both directions.

Spherical Roller bearings are designed to carry heavy loads, even under misalignment or shaft deflection. Spherical Roller bearings can also handle axial loading in either direction and heavy shock loads. Available with a cylindrical or a tapered bore for mounting with or without a sleeve adapter. Available with many internal clearance (C2 to C4) and retainer options. Available bore dimension range is 20mm to 900mm.

Spherical roller bearings are self-aligning bearings that are consequently insensitive to misalignment of the shaft, they have two rows of rollers so they are able to carry heavy radial loads, all sizes are available with cylindrical or tapered bores.
Spherical roller bearings are produced in several designs, depending on bearing series and size. The differences are
- the arrangement of the floating guide ring as well as
- the design of the inner ring and/or cages,
as described in the following.

C(J), CC--Two window-type steel cages, flangeless inner ring and guide ring centred on the inner ring

EC(J), ECC(J)--Two window-type steel cages, flangeless inner ring, guide ring centred on the inner ring and reinforced roller complement.

CA--One-piece machined brass cage, double-pronged, retaining flanges on the inner ring and guide ring centred on the inner ring

CAF-- As CA, but with a steel cage.

ECA, ECAC-- Reinforced roller complement, one-piece machined brass cage, double-pronged, retaining flanges on the inner ring, guide ring centred on the inner ring.

ECAF-- As ECA, but with a steel cage.

E-- For bearings with a bore diameter d ≤ 65 mm: Two pressed window-type steel cages, flangeless inner ring and guide ring centred on the inner ring

CAFA-- One-piece machined steel cage, double-pronged, centred on the outer ring raceway, retaining flanges on the inner ring and guide ring centred on the inner ring.
 

 

• Double row spherical roller bearing for applications that support radial and oscillating axial loads
• C4 radial clearance allows thermal expansion for continuous operating temperatures up to 200 degrees C/392 degrees F
• Straight bore for fitting to a conventional cylindrical shaft
• Outer ring-guided brass cage evenly spaces rollers for reduced friction, vibration, and noise
• Open design, circumferential groove and three lubrication holes in the outer ring allow for lubrication in place
