The 61812/W64 is a single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and smooth operation. This metric bearing features a compact design with a 10 mm width, making it ideal for space-constrained assemblies. Its solid oil lubrication system ensures long-term, maintenance-free operation across a wide temperature range from -30°C to 120°C. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent precision and is compliant with ROHS and REACH environmental directives, offering a robust solution for general industrial use.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61812 | Standard series designation for a single row deep groove ball bearing with specific dimensions (60mm bore, 78mm OD, 10mm width). |
| W64 | Indicates the bearing is pre-lubricated with Solid Oil, a polymer matrix saturated with lubricant, providing a sealed-for-life, maintenance-free solution. |
61812/W64 Bearing Structural Features & Performance Benefits
- Optimized Radial Load Capacity: The single row deep groove raceway geometry is engineered to efficiently support significant radial dynamic load ratings (2675 lbf) and radial static load ratings (2563 lbf), ensuring stable performance under load.
- Maintenance-Free Operation: The integrated Solid Oil lubrication eliminates the need for re-lubrication, prevents lubricant leakage, and effectively excludes contaminants, significantly extending service life.
- Precision and Consistency: Manufactured from chrome steel for both rings and balls to ABEC 1 (ISO P0) tolerance, this bearing provides reliable running accuracy and low noise/vibration levels.
- Wide Operating Range: The Solid Oil and CN clearance allow for a broad operational temperature range (-30°C to 120°C) and a limiting speed suitable for many industrial applications.
61812/W64 Bearing Typical Application Areas
This bearing is well-suited for a variety of applications where compact size, reliability, and minimal maintenance are critical. Key sectors include:
- Electric Motors and Generators
- Small Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Conveyor Idler Rolls
- Agricultural Machinery
