51168 M Bearing Product Overview & Core Advantages
The 51168 M is a metric single direction thrust ball bearing engineered for demanding applications requiring high axial load capacity and precision. Its design is optimized to accommodate heavy thrust loads in one direction while maintaining stable operation. Manufactured from high-grade 52100 Chrome Steel for both rings and balls, it offers excellent durability and wear resistance. The open seal type allows for versatile lubrication options, making it suitable for high-speed scenarios where limiting speed is a critical factor. This bearing is characterized by its high axial dynamic and static load ratings, providing reliable performance in rigorous industrial environments.
51168 M Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 51168 | Standard bearing designation number, defining the core dimensions (340mm bore, 420mm OD). |
| M | Indicates the bearing is manufactured from copper-manganese alloy steel, offering enhanced dimensional stability and toughness. |
51168 M Bearing Structural Features & Performance Benefits
High Load Capacity: The robust construction, featuring a stainless steel cage for precise ball guidance, enables the bearing to handle exceptionally high axial dynamic load ratings (84825 lbf) and axial static load ratings (441000 lbf). This makes it ideal for applications with significant unidirectional thrust forces.
Precision & Stability: The bearing features tight dimensional tolerances on the bore, outside diameter, and width, ensuring a precise fit and reliable performance in high-precision assemblies. The specified chamfer dimensions facilitate easier installation.
High-Speed Capability: With a limiting speed of 1,100 rpm, the 51168 M is suitable for applications requiring moderate to high rotational speeds. The open design allows for efficient lubrication management to support these operational demands.
Material & Compliance: The use of 52100 Chrome Steel for critical components ensures long service life and resistance to deformation under load. The bearing is ROHS and REACH compliant, meeting modern environmental and safety standards.
51168 M Bearing Typical Application Areas
The 51168 M thrust ball bearing is commonly specified in heavy-duty machinery and precision equipment, including:
- Industrial Gearboxes and power transmission systems
- Heavy-Duty Pumps and Compressors
- Crane Hooks and lifting equipment
- Vertical Machining Centers and spindle supports
