Improper installation may cause damage gimbal bearing. Conditions such as high-speed operation, and higher operating temperature, special attention should be rotating rings can not be too loose to prevent eccentric, as well as non-fixed ferrule with a gap to prevent deformation under load and ferrule excite vibrations.
Rotating rings blanch the amount of interference to the extent possible should also get smaller. As long as the operating temperature and ensure the effect of thermal expansion, and the maximum speed of the centrifugal force, resulting in a tight fit so as not to creep or sliding surfaces. Fixed ferrule according to the work load size and gimbal bearing size, select small clearance fit or interference fit, too loose or too tight is not conducive to maintaining the original shape exactly. It is necessary to accurately calculate the rotation with the amount of interference rings, but also accurately calculate the amount of fixed rings fit. Shaft and housing bore roundness and verticality of the shoulder block gimbal bearing according to the appropriate precision requirements. Cage assembly precision guaranteed by the special assembly of mold, can be fully guaranteed gimbal bearing assembly accuracy.
For heavy load applications should normally be lighter than normal loads and loads of occasions with as tight. Heavier loads, and its interference with the greater should be. Using paired gimbal bearing spindle, mostly lighter loads, the amount of interference, such as too large, then the internal axial preload amount will be significantly larger, resulting in adverse effects. .
In order to determine whether removing the gimbal bearing re-use, to focus on checking the accuracy of its size, rotation accuracy, internal clearance and the mating surface raceway, cage and ring.
