6252 M Bearing Product Overview & Core Advantages
The 6252 M is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. Characterized by its P6 precision tolerance and open design, this bearing is optimized for high-speed operation and superior radial load capacity. Its robust construction, featuring chrome steel rings and balls with a stainless steel cage, ensures high rigidity and long-term operational reliability. The absence of seals minimizes friction, making it an ideal choice for applications requiring a limiting speed of 2,400 rpm.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6252 | Basic Bearing Series & Size | Denotes a metric, single row deep groove ball bearing with a 260mm bore, 480mm OD, and 80mm width. |
| M | Stainless Steel Cage | Indicates a machined brass cage, offering high strength and excellent guidance at high speeds. |
Note: The absence of a seal designation (Open) and specific internal clearance (CN) are inherent to the base model.
6252 M Bearing Structural Features & Performance Benefits
The performance of the 6252 M is derived from its precision engineering and material selection:
- High Load Capacity: With a dynamic load rating of 87,675 lbf and a static load rating of 119,149 lbf, this bearing is built to handle significant radial loads in heavy-duty machinery.
- Precision & High-Speed Capability: The P6 tolerance class ensures precise running accuracy, while the open design and stainless steel cage (M) contribute to a high limiting speed of 2,400 rpm by reducing friction and centrifugal forces.
- Robust Construction: Manufactured from chrome steel for rings and balls, the bearing provides excellent wear resistance and durability. The machined cage ensures stable ball guidance.
- Standard Internal Clearance: The CN radial internal clearance is the standard for normal operating conditions, providing a balance between temperature management and running precision.
6252 M Bearing Typical Application Areas
The 6252 M deep groove ball bearing is suited for a wide range of industrial applications requiring high precision and reliability, including:
- Industrial Gearboxes and large power transmission systems.
- Heavy-duty Electric Motors and generators.
- Material Handling Equipment such as conveyor pulleys.
- Large Pumps and Compressors.
- Mining and construction machinery.
