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 brass cage
