W 619/9-2RS1 Bearing Product Overview & Core Advantages
The W 619/9-2RS1 is a metric single row deep groove ball bearing designed for high-performance applications requiring reliable operation. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS1) which provides effective protection against contaminants while retaining lubrication, making it a maintenance-free solution for various industrial applications. This bearing is engineered to primarily handle radial loads and is characterized by its compact dimensions (9mm bore, 20mm OD, 6mm width) and low weight (0.0075 kg), making it ideal for space-constrained assemblies.
W 619/9-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W 619/9 | Basic bearing designation for a single row deep groove ball bearing series with a 9 mm bore diameter. |
| -2RS1 | The bearing is fitted with two rubber contact seals (RS1), one on each side. This provides superior sealing efficiency compared to non-contact shields, protecting against dust and moisture and retaining grease. |
W 619/9-2RS1 Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components—rings, balls, and cage—are made from stainless steel, providing excellent resistance to corrosion and enabling use in harsh environments.
- Effective Sealing: The 2RS1 rubber contact seals effectively exclude contaminants and retain the pre-applied grease, ensuring long-term, maintenance-free operation and extending bearing service life.
- Precision and Load Capacity: Manufactured to P0 tolerance class with a CN radial internal clearance, it offers reliable performance. With a dynamic load rating of 438 lbf and a static load rating of 209 lbf, it is capable of handling significant radial loads for its size.
- Operational Versatility: The pre-lubricated grease and wide operating temperature range (-30°C to +120°C) allow for reliable performance in diverse conditions. The limiting speed of 22,000 rpm makes it suitable for high-speed applications.
W 619/9-2RS1 Bearing Typical Application Areas
The W 619/9-2RS1 is ideally suited for applications demanding compact size, corrosion resistance, and sealed operation. Common uses include:
- Electric Motors and Small Gearboxes
- Medical and Dental Equipment
- Food Processing and Packaging Machinery
- Precision Instruments and Optical Devices
- Office Automation Equipment (e.g., printers, scanners)
