Composite bearing assembly

There are various possibilities for assembling composite bearing bushes. However, the most common assembly methods are (cold) shrink fitting and press fitting.

Bearing assembly

The best choice of bearing assembly method is often determined by the size of the bearing. A small bearing can easily be press-fitted but for large bearings, shrink fitting is often recommended. 

The method that offers the most advantages is nitrogen shrinking. The use of nitrogen guarantees shorter assembly times, limited risk of damage during assembly and excellent adhesion to exclude corrosion between the bearing and the bearing housing.

Press fitting

Bearings with an outer diameter of up to approx. 250mm can easily be pressed into their housing. Shrink fitting is the common choice for larger bearings. For press fitting, we recommend the use of a chamfered edge on the press side.
This simplifies the press fitting process, and prevents the risk of damage. Once the press fitting process has been started, the bearing must be fitted in a single continuous movement. If the process is halted at mid press, higher pressing forces may be required.

There are no objections to pre-treating the surface of the housing with an anti corrosive coating. However, we recommend maintaining a rough surface to prevent bearing slip.

Shrink fitting

On request, as well as providing all the information you need for assembly, we can carry out on-site assembly via shrink fitting. To guarantee the perfect performance of composite bearings, the correct assembly is essential. Our staff are specialists in bearing technology and can guarantee the perfect fitting of your bearings.
