Professional Installation Of The Nsk Bearing

- Jun 21, 2018 -

Professional installation of the NSK bearing 

Whether the bearing is installed correctly affects the precision, life and performance.Therefore, the design and assembly department should fully study the installation of bearings.You want to install according to the job criteria.The standard operating items are usually as follows:

(1) clean the bearing and bearing connection parts

(2) check the size and precision of the connected parts

(3) installation

(4) check after installing the bearing

(5) supply lubricant

It is hoped that the bearing package will not be opened until the installation is imminent.General grease lubrication, do not clean, directly fill the grease.Lubricants lubricated, also need not be cleaned commonly, but, equipment or high speed bearing, should be cleaned with clean oil, remove the antirust coating on the bearing.The bearing with the antirust agent removed, easy to rust, so can not be placed in disregard.In addition, bearings sealed with grease are not cleaned for direct use.

The method of bearing installation varies with bearing structure, fit and conditions. Generally, the inner ring needs to be over-filled due to the rotation of the shaft.Cylindrical bore bearings, multi - purpose press press press in, or multi - purpose heat installation method.For tapered holes, install directly on the taper shaft or sleeve.

When it is installed into the shell, there is usually more clearance fit, and the outer ring is overfilled. It is usually pressed by the press, or there is a method of cold shrinkage fit after cooling.Using dry ice as a coolant, the moisture in the air will condense on the surface of the bearing when it is cooled and fitted.Therefore, appropriate anti-rust measures are needed.
