Fine workmanship: the press blocks made of new aluminium alloy material with CNC machining, anodic hard oxidation treatment and cone design can effectively protect the bearings from damage when pressing, as only the outer ring touches the bearing shell. Besides, the threaded rod, the special T-thread spindle bar for CNC machine tools, can effectively improve tensile force and reduce wear.
Bearing press blocks: used for bottom bracket press fittings of both standard bearings (e.g. 1728 and BB70/ BB86/ BB90/ BB92/ BB30 etc.) and other non-standard bearings with similar inner and outer diameters to the above mentioned bearings. *Note: Headsets are prohibited.
Bicycle repair tool set: suitable for press mounting bicycle hubs, freewheels, bottom brackets, swivel bearings for soft rear frames. An excellent tool kit for bike repair.
【Easy to store】Equipped with a box (size: 33 × 27.5 × 8 cm), it is easy to store and carry, very convenient to use.
【How do I install the bearing?】① Choose the appropriate press block according to the diameter of the inner hole of the bearing. ② Turn and release the movable handle and slide the pressure block and bearing through the threaded rod to the firm grip. ③ Install the movable handle and turn it until it can no longer be pressed. Release the movable handle, take out the press block and the installation is complete.
