(1) deep groove ball bearings: simple in structure, easy to use. -6,000 installed and sealed, with the special requirements of Ukrainian places, can be used. Shielded dustproof is good, good sealing with sealing ring, with shields on both sides is mounted on the right amount of grease, work within a certain period no longer come on. General bearing inner ring width for device sealing and fixing screws or an eccentric form, installation, Assembly and ease of use, higher requirements applicable to seal the long axis, when installing or loading bending, leaning on the larger axis, manufacture and installation of low precision to a host.
(2) self-aligning ball (roller) bearings: mainly used in large bends under the load of the drive shaft, and the bearing block hole difficult to guarantee strictly concentric areas. Spherical roller bearings of carrying capacity, particularly suitable for heavy loads or vibration.
(3) cylindrical roller bearing: allows the skewness of the outer rings and inner ring axis small (2'~4'), it can only be used for rigid on the larger axis, and bearing very good. Commonly used in the outside bend of smaller fixed on the short axis, or on a mechanical shaft elongation due to the heat, this time, on a fulcrum installation of roller bearings without flanges, on another point you should install the shaft and the bearing housing can be fixed up.
(4) products: for radial mounting dimensions restricted places.
(5) the tapered roller bearing: separable bearings, rings (including tapered roller and cage) and can be installed on the outer ring. In the process of installing and using radial and axial clearance of the bearing can be adjusted, pre-interference can also be installed. Single row radial loads under additional axial force, it is generally installed in pairs. If used alone, plus the axial force should be greater than the additional axial force. Mainly used for heavy machinery. Axial clearance of the bearings the size of a large influence on bearing can be good, past hour high temperature, excessive bearing damage.
(6) the thrust ball (roller) bearings: running process, plus the axial force of small, bearing is not pressing, due to the centrifugal force, and ball (roller) and the Raceway between slip and damage the normal functioning of the bearing, therefore, must exert enough axial forces, axial hour free bearing preload spring. Bearing two bearing surface must be parallel to, does not allow any deviation, shaft centerline perpendicular to the shell bearing surface shall ensure, if not guaranteed, free spherical seat washer or provocation to compensate.
