1. The compact bearing of the large bearing The force required for the bearing is increased with the increase of the bearing volume. Because the large bearing can not be easily pressed onto the shaft or pressed into the bearing seat; therefore, it is recommended to use a thermal device. If it is between the bearing and the shaft It is an interference cooperation; the bearing should be heated. If there is interference between the bearing and the bearing housing, the bearing housing should be heated. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
2, the dismantling of small and medium-sized bearings by the interference cooperation method Most of the small and medium-sized bearings installed on the shaft can be opened by the conventional puller. SKF advocates the use of TMM series pullers; this is a self-centered pull Puller; with a common spring-loading arm; used to facilitate the disassembly operation. In special cases; the inner ring or the outer ring can not be touched; can use a dedicated internal pull-type bearing puller.
3, simple and easy to open the inner ring of the cylindrical roller bearing is generally selected for thermal disassembly. Therefore, SKF has developed a series of special items for induction heating. If the demand is often opened, the inner ring of various diameters; SKF adjustable induction heating The device is a quick thing.
4, the compact bearing of the small bearing device requires the force of the bearing to increase the volume of the bearing and add agile. If the bearing and the shaft are interference cooperation; then the bearing can be heated. If the bearing and the bearing block are interspersed Cooperation; the bearing housing can be heated. SKF supplies all kinds of heating things; can complete the heat device mission simply and properly. SKF electric heating plate is a professional heating equipment; designed for preheating small bearings in front of the device.
5, small bearings on the shaft of small bearings with a bore diameter of less than 50 mm; can be cooled with TMFT devices. Medium-sized bearings with a hole diameter of 100 mm; generally can be cooled by mechanical presses or hydraulic presses. Medium-sized bearings up to 100 mm; mechanical or hydraulic heaters are generally used for cold installations.
