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
    • Improved bearing performance in extreme operating conditions, minimizing impact of contaminants that can get caught in the bearing's roller and cage due to an enhanced cage bridge design
    • Extend bearing life in applications with extreme shock/vibration, high gravitational forces and minimal lubrication conditions due to the extra strength and durability provided by our machined brass cage
