W 61701 R-2RS1 Bearing Product Overview & Core Advantages
The W 61701 R-2RS1 is a metric single row deep groove ball bearing engineered for high performance in compact spaces. Its core advantages stem from its stainless steel construction and integrated sealing (2RS1), providing excellent corrosion resistance and protection against contaminant ingress. This bearing is designed to handle primarily radial loads efficiently, making it a reliable and durable choice for applications demanding precision, cleanliness, and long-term reliability in a small footprint.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel bearing. |
| 61701 | The bearing series and size designation (12mm bore, 18mm OD, 4mm width). |
| R | Indicates a flanged outer ring, aiding in axial location and simplified mounting. |
| 2RS1 | Signifies contact seals on both sides, offering superior protection against dust and moisture compared to non-contact shields. |
W 61701 R-2RS1 Bearing Structural Features & Performance Benefits
Compact & Robust Design: The single row deep groove geometry and flanged outer ring provide a space-saving solution with enhanced mounting stability. The all-stainless steel construction (rings, balls, cage) ensures high corrosion resistance and is suitable for washdown environments.
Effective Sealing: The 2RS1 double lip seals make the bearing grease-retaining and effectively exclude contaminants, contributing to a longer service life and reduced maintenance needs.
Precision & Load Capacity: Manufactured to P0 tolerance class and CN radial internal clearance, this bearing offers reliable running accuracy. It is optimized for radial dynamic load applications, with a rated capacity of 118 lbf.
Pre-lubricated & Ready-to-Use: The bearing is pre-filled with grease, making it maintenance-free for its entire service life under normal operating conditions within its specified temperature range of -30°C to 120°C.
W 61701 R-2RS1 Bearing Typical Application Areas
The W 61701 R-2RS1 is ideally suited for applications requiring miniature, sealed, and corrosion-resistant ball bearings. Common uses include:
- Small Electric Motors (e.g., miniature DC motors, stepper motors)
- Precision Instruments and Medical Devices
- Office Automation Equipment (printers, scanners, copiers)
- Food & Beverage Machinery (due to stainless steel construction)
- Guidance rollers, idler pulleys, and other light-duty radial load applications.
