6244 M Bearing Product Overview & Core Advantages
The 6244 M is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This precision bearing is designed primarily to handle significant radial loads, making it a robust and reliable choice for high-speed machinery. Its key advantages include a high radial dynamic load rating of 66,543 lbf, a P6 tolerance class for superior running accuracy, and an open design that allows for versatile lubrication options. Constructed entirely from chrome steel for the rings and balls, with a durable stainless steel cage, it offers excellent durability and a long service life.
6244 M Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| 6244 | Basic bearing series and size designation (Bore: 220mm, OD: 400mm, Width: 65mm). |
| M | Indicates the cage is made from machined brass. This design offers high strength, excellent guidance, and is suitable for very high-speed applications and demanding operating conditions. |
6244 M Bearing Structural Features & Performance Benefits
- Optimized for High-Speed Operation: The machined brass (M) cage provides exceptional stability and low friction at high rotational speeds, contributing to the bearing's impressive limiting speed of 3,000 rpm. This makes it an ideal high-speed bearing.
- Superior Load Capacity: The deep groove raceway and robust construction enable it to support high radial dynamic and static loads (66,543 lbf and 82,055 lbf respectively), ensuring reliable performance under heavy loads.
- High Precision & Rigidity: Manufactured to a P6 tolerance class, this bearing guarantees precise shaft running and minimal vibration, which is critical for applications requiring high positional accuracy.
- Versatile Lubrication & Maintenance: The open seal type allows for the use of various lubricants (oil or grease) tailored to specific operational needs, such as extreme temperatures or high speeds. The standard CN radial internal clearance is suitable for most common operating conditions.
