W 61804-2RS1/VT378 Bearing Structural Features & Performance Benefits
Robust Construction: The single row design with a stainless steel cage and components provides a balanced combination of strength and corrosion resistance. The deep groove raceway is optimized for handling radial dynamic loads and axial loads from both directions.
Sealed and Lubricated for Life: The 2RS1 contact seals are a critical feature, effectively shielding the internal components from dust, moisture, and other contaminants while retaining the pre-applied VT378 grease. This creates a maintenance-free system, eliminating the need for re-lubrication and reducing lifecycle costs.
Precision and Speed: Built to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, this bearing ensures smooth and quiet operation. It is capable of achieving a limiting speed of 13,000 rpm, making it suitable for various high-speed applications.
