Bearing accessories are essential components that ensure the correct installation, positioning, removal and stable operation of bearings. They include a wide range of items such as locking sleeves, removal sleeves, nuts, washers and other auxiliary fittings. Among these, locking sleeves securely fix bearings with tapered bores onto smooth shafts, simplifying the installation process and ensuring reliable positioning; removal sleeves facilitate the non-destructive removal of bearings, reducing maintenance complexity and minimising damage to both the equipment and the bearings; bearing nuts are used for axial positioning and preload adjustment, ensuring that the bearing does not move axially during operation; washers and other accessories serve auxiliary functions such as anti-loosening, sealing and cushioning, further enhancing the operational stability and reliability of the bearing system. Working in concert, these various accessories effectively optimise the bearing’s installation accuracy and load-bearing conditions, extending the bearing’s service life. They are widely used in various industrial equipment, including metallurgy, mining, construction machinery, textile machinery and fans, providing comprehensive assurance for the stable operation of bearing systems and serving as an indispensable component in bearing applications.
