W 63800 R-2Z Bearing Product Overview & Core Advantages
The W 63800 R-2Z is a single row deep groove ball bearing engineered for exceptional performance in compact spaces. Constructed entirely from stainless steel, it offers superior corrosion resistance and durability. Its key advantage lies in its ability to efficiently handle radial loads while its shielded design ensures long-term reliability. This bearing is characterized by its high precision P0 tolerance and pre-lubrication, making it an ideal, maintenance-free solution for applications demanding high rotational accuracy and operational cleanliness.
W 63800 R-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W | Stainless Steel Bearing Series |
| 63800 | Basic bearing designation, defining the core dimensions: 10mm bore, 19mm OD. |
| R | Flanged outer ring design, facilitating precise axial location and simplified mounting. |
| 2Z | Shielded on both sides. This provides effective protection against contaminant ingress while retaining the grease lubrication, contributing to the bearing's maintenance-free characteristic. |
W 63800 R-2Z Bearing Structural Features & Performance Benefits
- Compact & Robust Flange Design: The flanged outer ring (21mm outer diameter) ensures easy and secure installation, preventing axial displacement and simplifying housing design.
- High Corrosion Resistance: Manufactured entirely from stainless steel (rings, balls, and cage), this bearing is ideal for harsh environments where moisture or chemicals are present.
- Optimized for Speed and Load: The deep groove raceway and precision construction enable smooth operation up to a limiting speed of 38,000 rpm, supporting a dynamic load rating of 333 lbf.
- Maintenance-Free Operation: The combination of non-contact ZZ shields and factory-applied grease creates a sealed, lubricated-for-life unit, reducing total cost of ownership.
- Precision Performance: Built to P0 tolerance class and standard CN radial internal clearance, it ensures consistent, low-vibration performance for precision mechanisms.
W 63800 R-2Z Bearing Typical Application Areas
This bearing's compact size, corrosion resistance, and high-speed capability make it suitable for a wide range of demanding applications, including:
- Precision Medical and Dental Equipment (e.g., handheld tools, small pumps)
- Food Processing and Packaging Machinery (requiring washdown and corrosion resistance)
- Small Electric Motors and Gearboxes
- Instrumentation and Control Devices
- Office Automation Equipment (e.g., printers, scanners)
