Thrust bearings have four-point angular contact ball bearings, double row (single row) angular contact ball bearings, bidirectional copper alloy bearing thrust cone and cylindrical roller bearings, also recently developed a brake roller bearing radial bearings.

    Four-point angular contact ball bearings, double (single) row angular contact ball bearings used as thrust bearings, the prohibition of radial reciprocating motion bearings to accept the load, so the bearing housing bore corresponding to the assembly of these bearings, its diameter is necessary 0.5mm larger than the outer diameter of the bearing. Or less than the diameter of the bearing diameter of 0.5 mm or so. {TodayHot}

     For four-point contact ball bearings, do not exchange the same type of split ring when installing the device to prevent the self-lubricating flanged sleeve from changing the axial clearance at the time of shipment.

Two-way thrust tapered roller or two-way thrust cylindrical roller bearings in the circle, the same type of bearings do not exchange, in order to prevent changes to the factory when the axial clearance.

Thrust bearing inner surface of the end device is necessary compression, but also to lock the axial. In order to prevent its relative rotation on the roll neck, the formation of roll neck co-wear surface, burns.

Brake roller axial force bearings are used after two axial positioning of the bearing box, and adjust the axial clearance. In the device bearing box, should ensure that the bearing inner and outer rings and inner and outer rings of the main bearing tight. When fixing both sides of the bearing housing in the axial direction of the machine frame, take care to eliminate the axial movement of the bearing housing in the direction of the shaft end during the process of introducing the bearing housing into both sides.
