• 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
