(1), NTN cleaning bearings and bearing association member
(2), check the related parts size and fine processing
(3), installation
(4), NTN bearing inspection after installation
(5), supply of lubricant
Hope that in the pre installation, just open the NTN bearing package. General grease lubrication, no cleaning, directly filling grease. Lubricating oil, general need not cleaning, however, instruments or high speed NTN bearing, to use clean oil wash, remove antirust coating in the bearing. Remove the bearing, anti rust agent is easy to rust, so cannot be placed aside. Furthermore, has grease sealed bearings, not washing directly use.
NTN bearing installation methods, because the bearing structure, coordination, conditions vary, in general, due to rotate, so the inner ring interference fit is required. Bearings with a cylindrical bore, multi-purpose press press, or use the hot charging method. Tapered bore, directly installed in the taper shaft, or sleeve installation.
Mounted to the housing, general clearance, there is interference in the outer ring, usually with presses into, or have shrink fit method of installing cooling. Using dry ice as a cooling agent, shrink fit occasion, surface moisture in the air condenses on the NTN bearing. So, need appropriate antirust measures.
NTN bearing cleaning: demolition of NTN bearing maintenance, the first recorded appearance of the bearings, confirm the remaining amount of lubricant, after sampling inspection by the lubricant, cleaning bearings. As a cleaning agent, general use gasoline, kerosene.
NTN bearings down clean, rough cleaning and fine cleaning, placed in a container, metal mesh on the bottom first, make the bearing does not directly contact the container dirt. Rough cleaning, if you rotate the bearings with dirt, can damage the bearings of rolling surface, should pay attention to. In the crude oil washing, use the brush to remove grease, adhesive material, generally after a clean, to wash.
Sperm washing, is the NTN bearings in cleaning oil while rotating, while careful cleaning. In addition, cleaning oil should be kept clean.
NTN bearings maintenance and judgment: dismantled in order to determine the bearing can be used to check whether, after bearing wash. Maintain and increase shelf wear, bearing clearance and the irrelevant dimension accuracy decreased injury, abnormal. Non separation of small ball bearings, inner ring with one hand supporting level, to confirm whether the smooth rotating ring.
Tapered roller bearings are divided from the shape of NTN bearing, can check the raceway surface, rolling body of the outer ring.
Because large bearing cannot rotate with the hand, check the rolling body raceway, cage, retaining boundary surface appearance, the importance of NTN bearing shall carefully check the higher.

NTN bearing installation is correct or not, affect the accuracy, performance, service life. Therefore, the design and assembly departments for bearing installation to fully study. Want to be installed according to the operating standard. Operation standard projects usually are as follows:(1), NTN cleaning bearings and bearing association member
