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.
