The bearing
installation has close relationships with the accuracy,
life and performance. Therefore the design and
assembly departments should fully research into
the bearing installation.
It is better to implement installation according
to the operation standard. The items of the operation
standard are usually as follows: (1) Clean bearing and its related parts (2) Check the size and finishing conditions of the related
parts (3) Installation (4) Examine bearings after installation (5) Feed the lubricant
The bearing packing should be opened shortly before
installation. There is no need for cleaning to ordinary
lubricating grease lubrication, direct-filling of
lubricating grease or lubricating oil. Whereas it
should use the clean oil to rinse the instrument
purpose bearing or high speed purpose bearing etc.
and get rid of the anti-rusting agent on the bearing.
The bearing easily gets rusty without rust inhibitor.
Therefore special care should be taken to such kind
of the bearing.
What is more, the bearing which has been sealed
with lubricating grease can be put into direct use
with no cleaning at all.
The installation methods of the bearing vary according
to the difference in the bearing structure, matching,
condition. As it is mostly of axle rotation, the
inner ring needs interference fit. The cylindrical
bore bearing is commonly pressed in by pressing
machine or most probably, it adopts the heat installation
method. The taper hole can be directly
installed in the taper axle or by sleeving.
When it has been mounted to outer casing, usually
it has excess clearance fit, the outer ring has
shrink range, it will be pressed in
