W 619/3 R-2Z Bearing Product Overview & Core Advantages
The W 619/3 R-2Z is a single row deep groove ball bearing designed for high-precision applications requiring compact dimensions and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle radial loads efficiently while its shielded (2Z) design and pre-applied grease lubrication ensure long-term, maintenance-free operation in demanding environments. This bearing is ideal for applications where space is limited and operational reliability is critical.
Model Code Breakdown
- W 619/3: Basic designation for a single row deep groove ball bearing with a 3 mm bore.
- R: Indicates a flanged outer ring, facilitating secure and simplified mounting.
- 2Z: Signifies that the bearing is shielded on both sides. This provides effective protection against contaminant ingress while minimizing friction, contributing to the bearing's high limiting speed.
W 619/3 R-2Z Bearing Structural Features & Performance Benefits
Compact & Robust Flange Design: The integrated flange on the outer ring allows for easy axial location and secure mounting, simplifying assembly and enhancing structural stability in compact housings.
Shielded for Protection & Speed: The non-contact shields on both sides effectively seal the bearing against dust and debris without significantly increasing friction. This design is a key factor in achieving the high limiting speed of 75,000 rpm.
All-Stainless-Steel Construction: The use of stainless steel for the rings, balls, and cage provides superior corrosion resistance, making the bearing suitable for applications exposed to moisture, chemicals, or requiring frequent washdowns.
Pre-Lubricated for Longevity: Filled with a high-quality grease, the bearing is lubricated for life, ensuring smooth operation and reducing maintenance requirements across its specified temperature range of -30°C to 120°C.
W 619/3 R-2Z Bearing Typical Application Areas
The W 619/3 R-2Z is ideally suited for a wide range of small, high-speed, and precision machinery, including:
- Small Precision Motors and stepper motors
- Medical and Dental Handpieces
- Optical Encoders and precision instrumentation
- Small fans and blowers
- Office automation equipment (e.g., printers, scanners)
- Robotics and miniature gearboxes
