Linear bearings

Spherical bearing priority for applications that require equipment and spare parts for simple cases, such as for agricultural machinery, transportation systems or construction machinery. Mainly used to bear radial load mainly radial and axial joint load, generally should not alone bear the axial load, such bearings can be installed separately inner ring (with a whole group of roller and cage) and the outer ring. This kind of slewing bearing does not allow a tilt axis relative to the housing, the radial load appointments will produce additional axial force. This kind of bearing axial clearance of the size of the bearing can work in large, when the axial clearance is too small, the higher temperature; axial clearance is large, angular contact ball bearing easily damaged. Therefore, in the installation and operation of special attention to adjust the bearing axial clearance, if necessary, preloaded mounting, in order to increase the rigidity of the bearing.
"NACHI bearing joints":
There lubricated bearings and self-lubricating type. Joint bearing is a special structure of sliding bearings. Its structure is simpler than the rolling bearing, which mainly consists of a spherical outer ring within a composition that can withstand a greater load, according to one of the inner and outer sphere of its different types and structures that can withstand the radial load , axial load or radial, axial joint load simultaneously. Generally used for slower swing movement (ie angle op-shaped, but also in a certain range of angles for the tilt movement (ie, aligning movement), the sliding surface of the spherical moving), the supporting shaft and shaft housing bore concentricity large, still work properly.
"Linear bearings":
Linear motion ball bearings are mainly used in machinery and equipment in linear reciprocating motion of the site, with a low friction, flexible movement and ease of maintenance and replacement. It is widely used in textile machinery, printing machinery, pharmaceutical machinery, precision machine tools, electric cutting machines and automatic recorder and other fields.
"NSK angular contact bearings":
 
    FAG angular contact ball bearings can bear radial load and axial load, but also can vary with pure axial load, the speed limit is higher. This kind of bearing axial load capacity determined by the contact angle, the contact angle is large, the ability to withstand high axial loads.
"Pressure bearing":
 
    Pressure bearings are separable bearings, according to its structure is divided into unidirectional and bidirectional pressure ball stress ball bearings. Uniaxial pressure bearings can withstand axial load in one direction, two-way pressure bearing can withstand axial load in both directions. Neither of them can bear radial load.
