61936 MA/C3 Bearing Product Overview & Core Advantages
The 61936 MA/C3 is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This precision bearing features a robust machined metal cage and is supplied with a C3 radial internal clearance, making it ideally suited for applications with elevated operational temperatures or where interference fits are used. Its design provides high reliability and long service life under significant radial loads, offering a compact and cost-effective solution for a wide range of machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61936 | Basic bearing series and size designation (180mm bore, 250mm OD, 33mm width). |
| MA | Indicates a machined brass solid cage, guiding the balls effectively and offering high strength and thermal stability. |
| C3 | Specifies a greater than normal radial internal clearance. This is critical for applications involving thermal expansion, heavy press fits, or where operational heat generation is significant. |
61936 MA/C3 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove construction and chrome steel components provide high radial dynamic load rating (26,752 lbf) and radial static load rating (30,124 lbf), ensuring stable operation under heavy loads.
- Optimized for Challenging Conditions: The standard C3 clearance prevents bearing seizure and reduces preload in applications with thermal expansion or interference fits, enhancing operational reliability.
- High-Speed Capability: The precision ABEC 1 | ISO P0 tolerance and the low-friction, robust machined brass cage (MA) contribute to a high limiting speed of 4,300 rpm.
- Versatile & Durable: With an open seal type and no pre-applied lubrication, it allows for custom lubrication schemes. The wide temperature range (-30°C to 120°C) ensures performance in various environments.
61936 MA/C3 Bearing Typical Application Areas
This bearing is commonly specified in industries and equipment requiring robust performance and reliability, including:
- Electric Motors and Generators (medium to large frame sizes)
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (conveyor pulleys, rollers)
- Agricultural and Construction Machinery
- Pumps and Compressors
