The NACHI thrust ball bearing model 53202 is a precision axial bearing designed to support unidirectional axial loads. It features a 15-millimeter inner diameter, 32-millimeter outer diameter, and a total thickness of 13 millimeters. The bearing consists of three main parts: a shaft washer, a housing washer, and a set of hardened steel balls. Dimensional accuracy complies with ISO 104 standards and tolerance class P6. The ball surface hardness ranges from 60 to 64 HRC, and the rings are made of 52100 chrome alloy steel. The optimized raceway geometry ensures uniform stress distribution and minimizes friction under high-speed operation.
Manufacturing of the NACHI 53202 thrust ball bearing involves precision grinding and controlled heat treatment, increasing fatigue life by up to 1.5 times. It operates within a temperature range of minus 20 to plus 120 degrees Celsius. Lubrication is achieved using lithium-based NLGI-2 grease or ISO VG 68 oil. The permissible rotation speed is up to 4500 rpm with grease and 6500 rpm with oil. This bearing is mainly used in power transmission systems, vertical shafts, and precision industrial machinery.
