Description: Spherical roller bearing
Race: we use the most advanced technology-cold extrusion process. Besides, the race will make two or three times temper to guarantee its high precision.
Rolling element: we use the rolling technology to process the roller and the steel ball of high precision bearing, the most
advantage of our technology is to promote productive and productive efficiency. At the same time, our technology can prolong the bearing working life. The hardness and the diamention stability will also promote.
Steel cage: in order to avoid avoid cracks and guarantee the hardness, we use pattern "high temperature+long time", our cage of high precision bearing have reached advanced level in china at surface abrasion resistance and fatigue strength.
C(J), CC--Two window-type steel cages, flangeless inner ring and guide ring centre on the inner ring
EC(J), ECC(J)--Two window-type steel cages, flangeless inner ring, guide ring centre on the inner ring and reinforced roller
complement.

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
Features:
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
