D/W R168 Bearing Product Overview & Core Advantages
The D/W R168 is a precision single row deep groove ball bearing designed for demanding applications requiring high reliability and dimensional stability. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its open design allows for versatile lubrication options while its CN radial internal clearance and P0 tolerance class ensure consistent performance. This bearing is engineered to primarily handle radial loads efficiently in a compact form factor.

D/W R168 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The bearing rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and making it ideal for applications exposed to moisture or chemicals.
- High-Speed Capability: The open design and stainless steel cage minimize friction and allow for a limiting speed of 75,000 rpm, suitable for high-velocity spindles and instruments.
- Precision Performance: Manufactured to P0 tolerance class with a tight bore diameter tolerance of -0.00019" to 0.00019", ensuring smooth and accurate rotation for precision equipment.
- Compact & Lightweight: With a bore diameter of 0.25", outside diameter of 0.375", and a weight of only 0.0005 kg, it is an excellent choice for space-constrained and weight-sensitive designs.
D/W R168 Bearing Typical Application Areas
The D/W R168 is ideally suited for a wide range of applications where corrosion resistance, high speed, and compact bearing size are critical. Key industries and equipment include:
- Medical and Dental Instruments: High-speed handpieces, surgical tools.
- Precision Instrumentation: Optical encoders, measuring devices, gyroscopes.
- Food and Beverage Processing Equipment: Conveyor rollers, mixers requiring washdown compatibility.
- Small Electric Motors: Miniature DC motors, fan motors.
- Aerospace and Defense Avionics: Guidance systems, instrumentation.
