W 619/6 Bearing Product Overview & Core Advantages
The W 619/6 is a metric single row deep groove ball bearing designed for high precision and reliable performance in compact spaces. Constructed entirely from stainless steel, it offers excellent corrosion resistance. As a fundamental radial bearing, it efficiently handles radial loads and, due to the deep groove raceway design, can accommodate limited axial loads in both directions. Its open design and high limiting speed make it suitable for applications demanding high rotational accuracy and smooth operation.
W 619/6 Bearing Model Code Explained, Specifications & Naming Convention
The model designation W 619/6 can be broken down as follows:
- W: Manufacturer's prefix/series identifier.
- 619: Bearing series, indicating a very light series with a 6mm bore.
- /6: Specifies the bore diameter of 6 mm.
Key implicit specifications based on the provided data include:
- Seal Type: Open - Allows for higher speeds and is suitable for environments where external sealing is provided.
- Tolerance Class: P0 (Normal) - Standard grade for general applications.
- Radial Internal Clearance: CN (Normal) - Standard clearance for most operating conditions.
- Lubrication: None - Bearing is supplied without grease, allowing for application-specific lubrication.
W 619/6 Bearing Structural Features & Performance Benefits
The performance of the W 619/6 is a direct result of its robust construction and material selection.
- All-Stainless-Steel Construction: The rings, balls, and cage are made of stainless steel, providing superior corrosion resistance and making the bearing ideal for applications exposed to moisture, chemicals, or requiring washdown.
- High-Speed Capability: The open design and precision-ground components minimize friction and heat generation, enabling a high limiting speed of 63,000 rpm.
- Radial Load Capacity: The deep groove raceway is optimized to support significant radial dynamic and static loads (171 lbf and 60 lbf respectively), ensuring long service life under load.
- Precision & Low Noise: Manufactured to P0 tolerance with a CN radial clearance, this bearing offers consistent running accuracy and smooth, quiet operation.
W 619/6 Bearing Typical Application Areas
The compact bearing dimensions (6x15x5 mm), low weight, and high-speed performance of the W 619/6 make it a versatile component across numerous industries. Common applications include:
- Precision Instruments: Small motors, optical encoders, and medical devices.
- Electric Motors: Spindle support in small, high-speed DC motors and fans.
- Office Automation Equipment: Printers, scanners, and copiers.
- Robotics: Joints and actuators in small-scale robotic arms.
- Food and Beverage Processing: Equipment requiring corrosion-resistant components.
