Description

Basic Parameters

The basic parameters of Thrust Ball Bearing: 51405M include an inner diameter of 25 mm, an outer diameter of 60 mm, and a height of 24 mm, defining its compact axial-mounting dimensions. As a single-row thrust ball bearing with a 90° contact angle, it is specifically designed to handle heavy axial loads in one direction while having limited capacity for radial loads. The bearing is rated with a dynamic load capacity (Cr) of approximately 38,500 N and a static load capacity (Cor) of around 78,500 N, indicating its performance under continuous and instantaneous axial loading conditions, though exact values may vary by manufacturer. It features a limit speed of up to 3,000 RPM (dependent on lubrication type and operating temperature), making it suitable for moderate-speed applications where precise axial positioning and high thrust resistance are required. These parameters collectively ensure the bearing’s effectiveness in applications such as machine tool spindles, automotive transmissions, and industrial pumps, where primary load direction is axial and space constraints demand a slim, lightweight design.

 

 

Product Application

The Thrust Ball Bearing: 51405M is engineered for applications requiring efficient management of heavy unidirectional axial loads while maintaining compact dimensions and precise axial positioning. Its single-row design with a 90° contact angle specializes in handling thrust forces along the shaft axis, making it ideal for machinery where radial loads are minimal or secondary.

 

In machine tool spindles, the bearing ensures stable axial alignment of rotating components, critical for maintaining precision in lathes, milling machines, or grinders where axial thrust from cutting forces must be controlled. In automotive transmissions, it withstands the axial loads generated by gear meshing in manual or automatic gearboxes, supporting smooth shifting and reducing wear on adjacent components. Industrial pumps and compressors benefit from its high static load capacity (Cor: ~78,500 N), efficiently countering axial forces from fluid pressure or mechanical vibrations to prevent shaft displacement and ensure consistent operation.

 

The bearing’s compact size (25 mm ID, 60 mm OD, 24 mm height) makes it suitable for space-constrained systems, such as electric motors in robotics or precision instruments, where lightweight design and reliable axial support are essential. It also excels in heavy-duty machinery like cranes, conveyors, or construction equipment, where it stabilizes rotating tables or load-bearing platforms under sustained axial thrust. In aerospace auxiliary systems and renewable energy applications (e.g., wind turbine yaw systems), its moderate limit speed (up to 3,000 RPM) and durable construction ensure long service life under cyclic loading conditions.

 

Designed for one-directional load paths, the 51405Mbearing is typically used in pairs or with radial bearings to manage combined loads, optimizing performance in applications like textile machineryprinting presses, or metalworking equipment. Its ability to handle high instantaneous axial loads (Cor) while maintaining low friction at moderate speeds makes it a cost-effective choice for industries requiring robust axial stability without compromising on space or weight. Overall, this bearing enhances equipment reliability in any system where primary load direction is axial, and a slim, high-thrust-resistant design is critical.
