Purpose and key benefit Precision press tool for installing bearings in hubs, bottom brackets, and frame swivel points. Designed to press only the bearing outer ring, protecting inner raceways, rollers/balls, and seals from damage during installation. Why you need it Prevents common bearing installation damage by avoiding direct force on internal components. Improves installation consistency and alignment, reducing rework and premature bearing failure. Reduces abrasion and wear on threaded components during heavy pulling operations. Main features Presses the cones/blocks while applying force only to the bearing outer rings that bear outer covers. Uses a T-threaded screw specifically matched to numerically controlled (NC) machine tools, improving pulling force and reducing abrasion on the screw. Suitable for installations where controlled, outer-ring-only pressing is required. Compatibility and function Intended for use with bearing hubs, bottom brackets, and frame swivel point bearings. Compatible with setups that use T-threaded screws common to NC machine tools; ideal where higher pulling force and reduced screw wear are required. Functions as a targeted pressing solution to protect bearing components and outer covers during assembly. Practical use scenarios Installing bearings into a hub assembly where protecting the inner race and rollers is critical for long service life. Fitting bottom bracket bearings or frame swivel point bearings in machinery frames to ensure correct seating without internal damage. Pressing bearings into flower drum, column base, or central axis assemblies where controlled outer-ring pressure and high pulling force are necessary. Performance and outcomes Delivers controlled, outer-ring-only pressing to minimize bearing damage. The T-threaded screw design enhances pulling capability and longevity of the tool in NC-machine environments. Reduces abrasion and mechanical wear during repeated installations, helping maintain consistent assembly quality.
