W 61807-2RZ Bearing Product Overview & Core Advantages
The W 61807-2RZ is a single row deep groove ball bearing designed for high-performance applications requiring reliability and precision. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RZ) with pre-applied grease lubrication, making it a maintenance-free solution ideal for protecting against contaminants. This bearing is engineered to primarily handle radial loads and is characterized by its compact cross-section, low friction, and capability to operate at high speeds, making it suitable for demanding and precision environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel bearing. |
| 61807 | The basic bearing designation, indicating a deep groove ball bearing with a 35 mm bore, 47 mm OD, and 7 mm width. |
| -2RZ | Signifies that the bearing is fitted with non-contact seals on both sides. This provides effective protection against dust and moisture while maintaining low running torque. |
W 61807-2RZ Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The rings, balls, and cage are made of stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments and applications requiring washdown.
- Sealed and Lubricated for Life: The 2RZ non-contact seals effectively shield the internal components from contaminants. Combined with factory-applied grease, this creates a maintenance-free system with a long service life within the specified temperature range.
- High-Speed Capability: The optimized internal geometry and low-friction seals contribute to a high limiting speed of 15,000 rpm, enabling its use in high-speed spindles and motors.
- Precision and Reliability: Manufactured to P0 tolerance class and standard CN radial internal clearance, this bearing ensures consistent performance, smooth operation, and high running accuracy.
W 61807-2RZ Bearing Typical Application Areas
This bearing is ideally suited for applications where corrosion resistance, high speed, and low maintenance are critical. Key industries and equipment include:
- Electric Motors and Generators
- Medical and Dental Equipment
- Food and Beverage Processing Machinery
- Precision Instruments and Optical Devices
- Pumps and Small Gearboxes
