The function of the bearing fit is to make the stationary and rotating rings of the NSK bearing and the stationary part (usually the bearing seat) and the rotating part (usually the shaft) of the mounting part, respectively, to achieve the transfer load and limit in the rotating state. The basic task of the motion system relative to the position of the stationary system.
On the shaft and in the housing, the rolling bearing requires its position to be fixed in three directions: radial, axial and tangential directions. Radial and tangential positioning is achieved by tight fit of the bearing ring. Axial positioning is only used in a few cases; usually axial stops are used, such as end caps and retaining rings. Limited to the clearance range.
Bearings should pay attention to the following four points when choosing to cooperate
The circumferential surface of the bearing ring should have good support and uniform force to reduce deformation and fully exert the bearing capacity of the bearing;
The bearing ring cannot slide in the tangential direction in its mating surface, otherwise the mating surface will be damaged;
The free end bearing must be compatible with the length change of the shaft and the housing bore, ie it must have the ability to accommodate the axial position to swim within a certain range;
NSK bearings must be easy to install and disassemble, saving labor, time and money.
It is very beneficial to make good use of the cooperation of NSK bearings. I also hope that everyone will fully consider the above four points of consideration when choosing.
For grease-lubricated bearings and oil seals or dust caps on both sides, the seal bearing does not need to be cleaned before installation. Check the size and finishing of the relevant parts.
1, grease lubrication
Relubrication of the bearings is best carried out during planned equipment downtime and is periodically replenished, while removing old grease or extruding old grease through the drain. Wipe the grease fittings clean before adding fresh grease. If the bearing housing does not have a grease fitting, the bearing housing cover or end cap should be opened to remove the old grease and, after cleaning, replenish the same type of fresh grease.
