W 61703-2RS1 Bearing Product Overview & Core Advantages
The W 61703-2RS1 is a metric single row deep groove ball bearing engineered for precision applications requiring high reliability. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS1) and pre-lubrication, making it a maintenance-free solution that effectively protects against contaminants. This bearing is designed to primarily handle radial loads and is characterized by its compact cross-section, with a minimal width of just 4 mm, making it ideal for space-constrained, high-precision assemblies.

W 61703-2RS1 Bearing Structural Features & Performance Benefits
- Corrosion Resistance & Longevity: The all-stainless steel construction ensures reliable operation in humid or corrosive environments, significantly extending bearing service life.
- Sealed & Lubricated for Life: The 2RS1 contact seals effectively retain grease and exclude contaminants. Combined with factory-applied grease lubrication, this creates a sealed, maintenance-free unit ideal for applications where re-lubrication is difficult.
- Precision & Low Noise: Manufactured to P0 tolerance class with a standard CN radial internal clearance, this bearing ensures smooth, quiet, and precise running, which is critical for sensitive instrumentation.
- Compact & Lightweight Design: With a width of only 4 mm and a weight of just 0.0039 kg, it is an optimal choice for miniaturized and lightweight designs without sacrificing performance.
W 61703-2RS1 Bearing Typical Application Areas
This bearing is suited for a wide range of applications where compact size, corrosion resistance, and maintenance-free operation are paramount. Key sectors include:
- Precision Instruments: Optical encoders, measuring devices, and small medical instruments.
- Small Electric Motors: Miniature motors for drones, RC models, and small appliances.
- Office Automation Equipment: Printers, scanners, and copiers.
- Food & Beverage Machinery: Equipment requiring frequent washdowns due to its stainless steel construction.
