Product Highlights

Bidirectional Axial Load Capacity: The dual raceway geometry delivers high rigidity and supports heavy combined radial forces and thrust loads from both directions.
Effective 2RS Contamination Defense: Contact NBR seals maintain lubricant retention and guard internal rolling elements from water splash, debris, and abrasive dust.
Optimized Running Accuracy: Precision-ground raceways ensure low noise output, minimal running friction torque, and steady thermal equilibrium at high speeds.
Plug-and-Play Maintenance Free: Factory pre-greased for ready-to-install implementation with zero initial greasing required.
