W 619/5-2RS1 Bearing Product Overview & Core Advantages
The W 619/5-2RS1 is a miniature deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS1) with pre-lubricated grease, providing effective protection against contaminants and ensuring long-term, maintenance-free operation. This bearing is designed to handle primarily radial loads and is optimized for smooth, quiet running at high speeds, making it ideal for demanding, space-constrained environments.

W 619/5-2RS1 Bearing Structural Features & Performance Benefits
- Full Stainless Steel Construction: The bearing rings, balls, and cage are manufactured from stainless steel, providing superior corrosion resistance and making it suitable for harsh environments and washdown applications.
- Effective Sealing: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants, while also retaining the lubricant. This significantly extends the bearing's service life and enables maintenance-free operation.
- High-Speed Capability: The precision deep groove raceway and optimized internal geometry contribute to low friction and torque, allowing for a high limiting speed of 32,000 rpm.
- Radial Load Capacity: The deep groove raceway is designed to efficiently support radial loads, with a dynamic load rating of 171 lbf and a static load rating of 75 lbf.
- Pre-Lubrication: Filled with high-quality grease, the bearing is ready for immediate use and provides reliable lubrication across its specified temperature range of -30°C to 120°C.
W 619/5-2RS1 Bearing Typical Application Areas
This miniature sealed bearing is commonly specified in applications where compact size, reliability, and corrosion resistance are critical. Key sectors include:
- Precision Instruments: Optical encoders, measuring devices, and small gauges.
- Small Motors and Drives: Stepper motors, miniature DC motors, and fan motors.
- Office Automation Equipment: Printers, scanners, and copiers.
- Medical Devices: Dental handpieces, small pumps, and laboratory equipment.
- Food and Beverage Machinery: Equipment requiring frequent washdowns due to its stainless steel construction.
