Super-Low Friction Torque Tapered Roller Bearing

Steeper contact angle
Larger diameter of rollers
Shorter roller length
Smaller number of rollers
Smaller PCD (pitch circle diameter) of rollers
Optimization of roughness and profile for large rib and roller end face

Oil inflow control through clearance between retainer and inner ring
Quicker discharge of oil by improved pumping performance

Special heat treatment for longer life
