Editrice NMB bearings when interference fit can divide a few kinds of installation method? When interference fit is adopted the NMB bearing installation method can be mainly divided into the following kinds: (1), pressure into the installation: into general use press installation, also can use a bolt and nut, when forced to use hammer into the pack. (2), heat set installation: the bearing in oil heating so that it has expanded again after installed on the shaft of the hot set method can avoid unnecessary force, the bearing in a short time, complete the installation. NMB bearing seal form and the selection of dust cover: NMB bearing seal form can be divided into open and closed type two kinds. Open type deep groove ball bearing with no sealing structure, closed deep groove ball bearings there are three basic forms: take dust cover bearing, take contact seal bearing, with non-contact seal bearing. As follows: 1, the dust cover bearing - on both sides of the belt ZZ( - z) Dust cover by stamping steel dust cover protection. Shielding is made from low carbon steel or stainless steel. 2, on both sides of the bearing - with non-contact seal 2 rz: NMB non-contact seal bearing is a kind of seal bearing with low friction torque, they are effective seal at the same time has a low friction torque, speed and low friction performance of non-contact sealed bearings is similar to the dust cover bearing. 3, on both sides of the bearing - with contact sealing ring 2 rs: using contact sealing ring has good sealing effect, especially as a result of the contact seal lip slip into inner ring sealing groove, prevent the dust from the outside into the NMB bearing effect is better. But as a result of the sealing lip friction, the friction torque is bigger.
