W 619/4 R Bearing Structural Features & Performance Benefits
- Flanged Design for Secure Mounting: The integrated flange on the outer ring (Flange outer diameter: 12.5 mm) simplifies axial location and mounting, reducing assembly time and cost while enhancing positional accuracy.
- All-Stainless Steel Construction: The rings, balls, and cage are manufactured from stainless steel, providing excellent corrosion resistance and making the bearing suitable for harsh environments and washdown applications.
- High-Speed Capability: With a limiting speed of 80,000 rpm, this bearing is engineered for high-speed applications, supported by its precision deep groove raceway and low-friction design.
- Precision and Reliability: Manufactured to P0 tolerance class and standard CN radial internal clearance, this bearing ensures consistent performance, low noise, and smooth operation.
- Open Seal & Custom Lubrication: The open seal type allows for custom lubrication strategies to optimize performance for specific operational conditions, while the standard non-lubricated version is ready for immediate use with compatible greases or oils.
W 619/4 R Bearing Typical Application Areas
This miniature flanged bearing is ideally suited for applications where space, weight, and corrosion resistance are critical. Key industries and equipment include:
- Precision Instruments: Optical encoders, measuring devices, and small medical instruments.
- Small Motors and Drives: Stepper motors, miniature DC motors, and fan motors.
- Office Automation Equipment: Printers, scanners, and copiers.
- Robotics and Automation: Small robotic joints, pick-and-place units, and guidance systems.
- Food and Beverage Machinery: Equipment requiring frequent washdowns and corrosion-resistant components.
