Part Number 232/530KYMBW906A, Spherical Roller Bearings

Longer bearing life achieved from higher capacity (vs. competitors)
Longer lubrication life achieved from lower operating temperatures due to reduced internal friction and running torque from cage guided rollers
Better contaminant purging from slots on cage face helps extend bearing life
Greater fatigue strength and increased wear resistance provide tougher protection against shock and acceleration loading from a brass cage
