61812-2RS1/W64L Bearing Product Overview & Core Advantages
The 61812-2RS1/W64L is a metric single row deep groove ball bearing designed for high reliability in compact spaces. Its key advantage lies in its sealed construction and Solid Oil lubrication, making it a maintenance-free solution for applications demanding long service life and contamination protection. This bearing is engineered to primarily handle radial loads and is characterized by its low friction and quiet operation, suitable for a wide temperature range from -30°C to 120°C. Its compact cross-section and standardized ABEC 1 | ISO P0 tolerance ensure consistent performance and easy integration.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61812 | Basic series designation for a metric, single row deep groove ball bearing with a specific bore (60mm), outside diameter (78mm), and width (10mm). |
| 2RS1 | The bearing features contact seals on both sides. The "RS1" suffix indicates low-friction, synthetic rubber seals that provide excellent protection against contaminants and retain lubricant effectively. |
| /W64L | This suffix signifies that the bearing is pre-lubricated with Solid Oil. This is a polymer matrix saturated with lubricating oil, offering superior performance in challenging conditions, including high speeds and extreme temperatures, while eliminating leakage. |
61812-2RS1/W64L Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 contact seals provide a high degree of protection against dust, moisture, and other contaminants, significantly extending bearing life and enabling use in harsh environments. This creates a maintenance-free system.
- Advanced Solid Oil Lubrication: The W64L lubrication technology ensures a consistent and reliable lubricant supply. It is ideal for high-speed applications (up to 11,000 rpm) and prevents oil leakage, even under centrifugal forces, which is critical for clean and efficient operation.
- High-Quality Material Construction: Manufactured entirely from chrome steel for the rings, balls, and cage, this bearing delivers high strength, durability, and resistance to wear, contributing to a long operational lifespan.
- Precision and Load Capacity: Built to ABEC 1 | ISO P0 tolerance standards with standard CN radial internal clearance, it offers reliable performance for general industrial use. The dynamic load rating of 2675 lbf and static load rating of 2563 lbf confirm its capability to handle significant radial loads.
61812-2RS1/W64L Bearing Typical Application Areas
The 61812-2RS1/W64L is ideally suited for a wide range of applications where reliability, compactness, and minimal maintenance are paramount. Key sectors include:
- Electric Motors and Generators
- Small Gearboxes and Power Transmission Systems
- Pumps and Compressors
- Material Handling Equipment (e.g., conveyor rollers)
- Office Automation Equipment and Precision Instruments
- Food and Beverage Processing Machinery (where non-leaking lubrication is beneficial)
