D/W R1-5-2Z Bearing Product Overview & Core Advantages
The D/W R1-5-2Z is a precision miniature ball bearing designed for applications demanding high reliability in compact spaces. As a single row radial ball bearing with shielded construction, it excels at handling radial loads while offering smooth operation. Manufactured entirely from stainless steel and pre-lubricated with grease, it provides excellent corrosion resistance and is suitable for a wide operating temperature range. Its compact dimensions and P0 tolerance class make it an ideal choice for high-precision, space-constrained mechanisms.
D/W R1-5-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| R1-5 | Indicates the specific bearing size series with a bore diameter of 0.0937" and outside diameter of 0.31252". |
| 2Z | Signifies that the bearing is equipped with shields on both sides. This provides effective protection against contamination while allowing for higher limiting speeds compared to contact seals. |
D/W R1-5-2Z Bearing Structural Features & Performance Benefits
- High Precision & Reliability: Built to P0 tolerance class with a bore diameter tolerance of -0.00019" to 0.00019", ensuring consistent performance and smooth running in precision assemblies.
- Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, and cage), making it suitable for harsh environments and applications requiring washdown or exposure to moisture.
- Maintenance-Free Operation: The 2Z shields retain the factory-applied grease, protecting the internal components from contaminants and providing long-term, maintenance-free service.
- Optimized for Compact Designs: With a minimal cross-section and a weight of just 0.000817 kg, this bearing is engineered for miniature applications where space and weight are critical constraints.
D/W R1-5-2Z Bearing Typical Application Areas
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Small Motors and Gearboxes: Stepper motors, miniature DC motors, and precision gearheads.
- Office Automation Equipment: Printers, scanners, and copiers.
- Robotics and Automation: Small robotic joints, conveyor belt rollers, and pick-and-place mechanisms.
