W 61900-Z/W64 Bearing Product Overview & Core Advantages
The W 61900-Z/W64 is a single row deep groove ball bearing designed for precision applications requiring high reliability and compact design. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include the ability to handle significant radial loads and its shielded design, which retains lubrication and protects against contamination. Pre-lubricated with Solid Oil, this bearing is essentially maintenance-free, making it ideal for applications where re-lubrication is difficult.
W 61900-Z/W64 Bearing Model Code Explained, Specifications & Naming Convention
The model number W 61900-Z/W64 is decoded as follows:
- W 61900: Denotes the basic bearing series, a miniature, deep groove ball bearing with a 10mm bore.
- -Z: Signifies that the bearing is equipped with a shield on one side. This shield protects the internal components from large particulate contaminants while helping to retain the lubricant.
- /W64: Indicates the bearing is lubricated with Solid Oil. This is a polymer matrix saturated with oil, providing long-term, maintenance-free lubrication and excellent resistance to wash-out.
W 61900-Z/W64 Bearing Structural Features & Performance Benefits
- Corrosion Resistance & Cleanliness: The use of stainless steel for the rings and balls ensures high resistance to rust and corrosion, making it suitable for harsh environments and applications requiring cleanliness.
- Maintenance-Free Operation: The combination of a shield (Z) and Solid Oil (W64) lubrication creates a sealed, long-life system. This eliminates the need for re-lubrication, reducing maintenance costs and downtime.
- High-Speed Capability: With a limiting speed of 45,000 rpm, this bearing is engineered for high-speed applications. The precision ABEC 1 (ISO P0) tolerance and optimized internal geometry contribute to smooth, low-vibration operation at high rotational speeds.
- Radial Load Capacity: The deep groove raceway and robust construction enable it to carry substantial radial dynamic loads (526 lbf), providing reliable performance in demanding conditions.
W 61900-Z/W64 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of compact, high-speed, and corrosion-sensitive equipment, including:
- Small electric motors and spindles
- Precision instruments and optical devices
- Medical and dental equipment
- Food processing and packaging machinery
- Office automation equipment (e.g., printers, scanners)
- Robotics and small gearboxes
