Structural features This assembly forms a flat disc shape and is composed of a tight ring fitted to the shaft, a loose ring fitted to the bearing housing, balls, and a cage. Load capability It is designed to withstand axial loads only and is not suitable for radial loads. Load direction options Unidirectional: bears axial forces in only one direction (such as axial thrust). Bidirectional: can bear axial forces in two opposite directions simultaneously. Applicable scenarios Suited for applications requiring axial positioning with low rotational speeds. Common uses include crane hooks, machine tool spindle ends, and automotive transmission shift mechanisms. Performance limitations and installation considerations Speed suitability: not wellsuited for speed operation; centrifugal force at higher speeds can increase ball wear. Installation precision: requires coaxiality; excessive deviation during installation can shorten service life. Key attributes to consider Function: axial load bearing only; discshaped bearing assembly. Compatibility: available in unidirectional and bidirectional variants. Size: not specified in this description (size details depend on model/datasheet). Material: not specified in this description. Performance: optimized for axial positioning at low speeds; wear and life are affected by speed and installation accuracy. Specific use scenarios Crane hook assemblies where axial positioning and low speed are required. End supports for machine tool spindles needing axial thrust support. Automotive transmission shift mechanisms requiring reliable axial guidance.
