Motor and generator INA bearing installation and removal methods

Easy heat installation of large bearings
　　Installing INA bearings force required for bearings with increased size and increasing rapidly. Due to the large bearings that cannot be easily or pressed into the bearing seats on the shaft, cylindrical roller bearings, it is recommended that heat installation. If it is an interference fit between bearing and shaft, the bearings should be heated. If you are an interference fit between bearing and housing, housing should be heated.
　　Remove small and medium bearing
　　To install an interference fit on the shaft of the most small general puller can be used INA bearing dismounting. TMMA INA recommended series puller this puller is a heart, with a unique spring arm, used to facilitate the removal operation. In exceptional cases, when the inner or outer rings are able to touch, you can use the dedicated pull-type bearing puller.
　　Simple heat removal
　　Inner rings of cylindrical roller bearings generally use heat removal. INA has developed a range of special tools for induction heating. If the diameter of the inner ring requires the regular demolition, INA may adjust the induction heater may be a convenient tool.
　　Small bearings easy heat installation
　　Force required for mounting bearings with bearing greater size and increased rapidly. If it is an interference fit between bearing and shaft, you can heat the INA bearing. If you are an interference fit between bearing and housing, the housings can be heated. INA provides all kinds of heated tools, able to complete simple and appropriate thermal installation tasks. INA electric heating pad is a professional heating equipment, specially designed for Preheat before installing Small bearings.
　　Cold small bearings on the shaft installation
　　Small bearings within aperture 50 mm, can be cold in TMFT installation tool to install. Aperture medium INA bearings in sizes up to 100 mm, usually can be cold in mechanical or hydraulic machine pressure machine installed. Aperture 100 mm within the medium bearing, its cold usually use a mechanical or hydraulic heaters installed.
