D/W R2 R Bearing Structural Features & Performance Benefits
- High Precision & Stability: Built to ABEC 1 (P0) tolerance class with a bore diameter tolerance of -0.00019" to 0.00019", ensuring smooth and accurate rotation critical for precision mechanisms.
- Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, cage), providing excellent protection against rust and corrosion in challenging environments.
- Flanged Design: The integrated flange (0.44" OD) simplifies mounting and provides secure axial location, reducing assembly complexity and cost.
- High-Speed Capability: With a limiting speed of 85,000 rpm, this bearing is engineered for high-speed applications. The open design minimizes friction and heat generation.
- Standard Clearance: Features a CN radial internal clearance, suitable for a wide range of operating conditions and common fit scenarios.
D/W R2 R Bearing Typical Application Areas
This versatile miniature flanged bearing is ideally suited for:
- Precision Instruments: Optical encoders, measuring devices, and laboratory equipment.
- Small Motors and Gearboxes: Stepper motors, servo motors, and miniature drive systems.
- Medical Devices: Surgical hand tools, dental drills, and diagnostic equipment.
- Office Automation: Printers, scanners, and copiers.
- Robotics and Automation: Small robotic joints, actuators, and guidance systems.
