D/W R144 R-2Z Bearing Structural Features & Performance Benefits
- Full Stainless Steel Construction: The rings, balls, and cage are made of stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments and washdown applications.
- Shielded Design (2Z): The non-contact shields on both sides protect the internal components from dust and other particulates, while the pre-applied grease lubrication ensures smooth operation and reduces maintenance needs.
- Flanged Outer Ring: The integral flange simplifies bearing mounting and positioning within a housing, saving space and reducing assembly time and cost.
- High-Speed Capability: With a limiting speed of 85,000 rpm, this bearing is engineered for high-speed applications, supported by its precision construction and effective lubrication.
- Standard Radial Clearance (CN): Provides a versatile internal fit suitable for a wide range of operating conditions and bearing loads.
