E type spherical roller bearing

E type spherical roller bearing is the newest design in the world. It adopts symmetrical spherical rollers, two quenched steel stamping cage, inner ring without flange and a middle ring guided by cage. The middle ring near the outer ring can improve the lubrication between the rollers’ end face and the flange ring, its function is to reduce the bearing’s friction, help guiding the roller in the non-load area, and assist the roller to enterin the load area, at the same time, the roller length increases, So the rated load has been greatly improved. Usually the rated load can be increased by 20-35.
Advantages:
1. Increase the quantity of rollers: higher load capacity.
2. Floating guide ring: Prevent vibration and improve the lubrication.
3. Bainite Hardening: wear resistance, impact resistance.
4. Inner sleeve without ribs, utral-fine polishing of inner ring, outer ring and rollers, roughness within 0.1μm: reducing friction largely.
