D/W R155 R Bearing Product Overview & Core Advantages
The D/W R155 R is a stainless steel miniature ball bearing designed for precision applications requiring corrosion resistance and reliable performance. This single row deep groove ball bearing features an open design and is engineered to handle primarily radial loads efficiently. Its compact inch dimensions, high-grade stainless steel construction, and compliance with RoHS and REACH standards make it an ideal choice for applications demanding high precision, cleanliness, and durability in challenging environments.
D/W R155 R Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| D/W | Manufacturer / Series Designation |
| R155 | Bearing Size / Dimension Series Code |
| R | Flange Design (as per specification: Flange outer diameter 0.35902") |
Key Configuration: The "Open" seal type allows for easy re-lubrication and minimizes friction, while the absence of a suffix for lubrication indicates it is supplied without grease ("None"), giving the design engineer full control over the lubrication process.
D/W R155 R Bearing Structural Features & Performance Benefits
- High Corrosion Resistance & Cleanliness: Constructed entirely from stainless steel (rings, balls, and cage), this bearing is inherently resistant to rust and corrosion, making it suitable for wet, washdown, or chemically aggressive environments. It is ideal for applications requiring high cleanliness.
- Robust Flange Design: The integrated flange (flange outer diameter: 0.35902") simplifies mounting and positioning, providing accurate location within a housing and enhancing overall assembly rigidity.
- Precision Performance: Manufactured to ABEC 1 (P0) tolerance class and standard CN radial internal clearance, this bearing ensures smooth and consistent operation, contributing to the precision of the overall mechanism.
- Wide Temperature Range: The stainless steel construction and open design enable a functional temperature range from -30°C to 120°C, accommodating a variety of operating conditions.
D/W R155 R Bearing Typical Application Areas
- Precision Instruments and optical devices
- Medical Equipment and dental handpieces
- Small Motors and miniature gearboxes
- Food Processing Machinery (where corrosion resistance is critical)
- Office Automation Equipment such as printers and scanners
- Various low-load, high-speed mechanisms
