D/W R2-6-2Z Bearing Product Overview & Core Advantages
The D/W R2-6-2Z is a precision miniature ball bearing designed for demanding applications requiring high reliability in compact spaces. As a single row deep groove ball bearing, it excels at handling radial loads while also accommodating moderate axial loads. Manufactured entirely from stainless steel and featuring integral shields, this bearing offers excellent corrosion resistance and is pre-lubricated for long-term, maintenance-free operation. Its inch dimensions make it ideal for replacement in American-designed equipment and precision instruments.
D/W R2-6-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| D/W | Manufacturer / Series Designation |
| R2-6 | Bore Size Code (0.125") |
| 2Z | Bearing with Shields on both sides. This provides effective protection against contamination while allowing for high-speed operation compared to contact seals. |
D/W R2-6-2Z Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments, including those requiring washdown or exposure to chemicals.
- Deep Groove Raceway: The geometry of the deep groove raceway is optimized to support significant radial loads and moderate axial loads from both directions, offering versatile load capacity in a compact design.
- Shielded Design (2Z): The non-contact steel shields retain the factory-applied grease lubrication and effectively exclude large particulate contaminants, contributing to a long service life and maintenance-free operation.
- Precision & High-Speed Capability: Built to P0 tolerance class with a standard radial internal clearance (CN), this bearing ensures smooth and quiet running. The combination of the stainless steel cage and optimized lubrication enables a limiting speed of 63,000 rpm.
D/W R2-6-2Z Bearing Typical Application Areas
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Small Motors and Gearboxes: High-speed stepper motors, servo motors, and miniature drive systems.
- Office Automation Equipment: Printers, scanners, and copiers.
- Radio Control Models: High-performance drone motors and RC car transmissions.
- Food and Beverage Equipment: Small pumps and conveyors where corrosion resistance is critical.
