51134 M Bearing Product Overview & Core Advantages
The 51134 M is a metric thrust ball bearing engineered for demanding applications requiring exceptional axial load capacity and precision. This bearing is specifically designed to accommodate thrust loads in a single direction, featuring a robust construction with high-grade components. Its key advantages include a high axial dynamic load rating of 29,925 lbf and an impressive axial static load rating of 121,500 lbf, making it suitable for high-stress environments. The open design allows for versatile lubrication options, while the precision tolerances ensure reliable performance in high-precision machinery.
51134 M Bearing Model Code Explained, Specifications & Naming Convention
The model designation 51134 M can be broken down as follows:
- 51134: Indicates a thrust ball bearing series with a 170mm bore and 215mm outside diameter.
- M: Signifies that the bearing is manufactured from copper-plated carbon chromium steel, though in this specification, the ring and ball material is 52100 Chrome Steel. The "M" often denotes a specific internal design or cage type. In this context, it aligns with the use of a stainless steel cage.
51134 M Bearing Structural Features & Performance Benefits
- Superior Axial Load Capacity: The bearing's geometry and use of 52100 Chrome Steel for both rings and balls provide an exceptional axial static load rating, enabling it to handle heavy thrust loads with high reliability.
- High-Speed Capability: With a limiting speed of 2,200 rpm, the bearing is suitable for applications requiring moderate to high rotational speeds. The stainless steel cage contributes to this performance by offering high strength and reduced friction.
- Precision Engineering: Tight dimensional tolerances on the bore diameter and outside diameter ensure precise fit and stable operation, which is critical for high-precision applications.
- Durability and Corrosion Resistance: The stainless steel cage enhances corrosion resistance, while the overall construction ensures long service life even under continuous thrust loads.
