W 61901-2Z Bearing Product Overview & Core Advantages
The W 61901-2Z is a single row deep groove ball bearing designed for exceptional performance in compact applications. Engineered from stainless steel throughout, it offers superior corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads while its shielded design protects against contamination. This bearing is characterized by its high precision (P0 tolerance class), low friction, and is pre-lubricated for immediate use, making it an ideal choice for applications demanding reliability and long service life in challenging environments.
W 61901-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel bearing. |
| 61901 | The bearing series and size designation (9mm bore, 24mm OD, 6mm width). |
| -2Z | Indicates the bearing is fitted with shields on both sides. This provides effective protection against the ingress of solid contaminants while allowing for high-speed operation. |
W 61901-2Z Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components (rings, balls, cage) are made from stainless steel, providing excellent resistance to corrosion and enabling use in wet or chemically aggressive environments.
- Optimized Radial Load Capacity: The deep groove raceway and single-row design are engineered to support significant radial dynamic (564 lbf) and static loads (328 lbf).
- Shielded for Protection & Longevity: The 2Z shields retain the factory-applied grease and protect the internal components from dust and debris, contributing to a maintenance-free and extended service life.
- High-Speed Capability: With a limiting speed of 32,000 rpm, this bearing is suitable for high-speed applications. The integral stainless steel cage ensures stable operation at these velocities.
- Pre-lubricated and Ready-to-Use: Filled with grease, the bearing is lubricated for life under normal operating conditions within its specified temperature range of -30°C to 120°C.
W 61901-2Z Bearing Typical Application Areas
This bearing's combination of compact size, corrosion resistance, and high-speed performance makes it ideal for a wide range of precision equipment, including:
- Small electric motors and spindles
- Medical and dental handpieces
- Precision instruments and optical devices
- Food processing and packaging machinery
- Office automation equipment (e.g., printers, scanners)
