Because of the given overlap sizes (outer diameter of the plain bearing/ bore hole of bearing housing) the elastic deformation of the bearing is used for building up the fit pressure (prestressing).

The bore hole of the bearing housing must be machined carefully and has to be supplied with an assembly bevel.

Under high temperatures higher overlap sizes may occur which are due to the different thermal expansion coefficients of the materials (plain bearing/ bearing housing).

Here, in order not to exceed the allowed fit pressure in the bearing housing, transition fits are used. In this case a fixing of the bearing has to be ensured

Installation of the bearing

The installation of the bearings can either be effected by force fitting or by subcooling with carbonic acid (CO2).

A specially made arbor press may be supplied by the company (relating to the order) to ease the force fitting and to avoid damages of the plain bearing.
