Key Features
- 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 hardened steel cage
