Methods the correct installation and test of SKF deep groove ball bearing

Deep groove ball bearing on the SKF Bearings equipment regular maintenance, operation and peripheral parts replacement was disassembled for inspection, in order to determine the time of deep groove ball bearing parts are available and record the use of good from bad again. Careful investigations and records of deep groove ball bearing and appearance were removed. SKF bearing installation is correct, affect the accuracy, performance, service life. Therefore, the design and assembly departments for bearing installation to fully study.
The operating standard items usually are as follows:
(1) cleaning of deep groove ball bearings and bearing association member
(2) the size and precision machining parts Inspection Association
(3) installation
(4) installing SKF bearing inspection after
(5) supply of lubricant
The method of installing SKF bearings, bearings, with the structure, 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. Taper of the occasion, directly installed in the taper shaft, or with the sleeve installation.
Mounted to the housing, general clearance, there is interference in the outer ring, usually with presses enter, 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 SKF bearing. Therefore, the need for appropriate antirust measures.
Cleaning of deep groove ball bearing: demolition of SKF bearing maintenance, the first recorded appearance of the bearings, confirmation of lubricant remaining quantity, sampling inspection by the lubricant after washing, bearing. As a cleaning agent, general use gasoline, kerosene.
SKF bearings down clean, rough cleaning and fine cleaning, placed in a container, put the metal net bottom, bearing no direct contact with the container. 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 SKF bearings in cleaning oil while rotating, while careful cleaning. In addition, cleaning oil should be kept clean.
Deep groove ball bearing maintenance and judgment: dismantled in order to determine the bearing can be used to check whether, clean in bearings. Check the raceway surface, rolling surface, with the surface state, increasing shelf wear, bearing clearance and the size of a precision injury, abnormal. Non separation of small ball bearings, inner ring with one hand supporting level, to confirm whether the smooth rotating ring.
