51415 M Bearing Product Overview & Core Advantages
The 51415 M is a metric thrust ball bearing engineered for demanding applications requiring high axial load capacity and precision operation. This open-type bearing is designed to accommodate thrust loads in a single direction, featuring a robust construction with 52100 Chrome Steel rings and balls for superior durability. Its key advantages include a high axial dynamic load rating of 56475 lbf and an exceptional axial static load rating of 137250 lbf, making it ideal for high-stress environments. The bearing's precise dimensional tolerances ensure reliable performance and ease of integration into high-precision assemblies.
51415 M Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| 51415 | Standard bearing designation number, defining the core dimensions (75mm bore, 160mm OD, 65mm width). |
| M | Indicates the use of a copper alloy cage (Note: Specification lists Stainless Steel cage, "M" may denote a specific manufacturer's designation or a variant. Please confirm with manufacturer datasheet). |
| (No Seal Suffix) | The absence of a seal suffix (e.g., 2Z, RS) confirms this is an open bearing, suitable for applications where external sealing is provided or where lubrication access is required. |
51415 M Bearing Structural Features & Performance Benefits
- High Load Capacity: Manufactured from 52100 Chrome Steel, both the rings and balls provide exceptional hardness and wear resistance, directly contributing to the high axial dynamic and static load ratings.
- Stainless Steel Cage: The stainless steel cage ensures high strength and corrosion resistance, maintaining ball alignment and integrity at the limiting speed of 1,800 rpm.
- Precision Ground Components: The tight dimensional tolerances on the bore, outside diameter, and width guarantee precise shaft and housing fits, leading to smooth operation and reduced vibration.
- Robust Design: With a substantial width of 65 mm, the bearing offers a large contact area, enhancing stability and its ability to handle heavy thrust loads.
- Compliance & Reliability: The bearing is ROHS and REACH compliant, ensuring it meets international environmental and safety standards for use in various industries.
51415 M Bearing Typical Application Areas
- Industrial Machinery: Heavy-duty thrust applications in gearboxes, pulverizers, and construction equipment.
- Power Transmission: Used in vertical pumps, marine propulsion systems, and crane hooks to manage substantial axial forces.
- Automotive & Aerospace: Steering mechanisms, actuation systems, and other assemblies requiring high axial load support.
- Machine Tools: Positioning tables and screw drives where precise axial movement under load is critical.
