On the shaft and bearing, SKF bearings require fixed in the radial, axial and tangential direction three position. Radial and tangential orientation through the tight fit of the bearing mining, axial position only in a few cases the use of tight fit; general axial spacing parts, such as the end cap and retaining ring to limit the axial position in the context of clearance.
Choose cooperation should focus on the following four points:
( 1 ) SKF the circumferential surface of bearing rings should have good support and force uniform, in order to reduce the distortion, and can give full play to the bearing capacity.
( 2 ) rings in their mating surfaces cannot slide along tangential direction, otherwise it will damage the mating surface.
( 3 ) SKF free end bearing must adapt to changes in length and shaft and the bearing seat hole, which must have the ability to adapt to the axial position within a certain range of swimming.
( 4 ) must pay attention to the SKF bearing installation and removal easy, spending is labor-saving and time-saving province.
