iglidur plain bearings are press-fit bearings. The inner diameter adjusts itself only after the bearing has been press-fitted in the H7 housing hole with the recommended tolerance. The press-fit interference can be up to 2% of the inner diameter. This ensures that the bearing is securely press-fitted. Axial or radial movement in the housing is also prevented in this way.
The hole in the housing should be made with the recommended tolerance (H7) for all bearings and be smooth, flat and chamfered. The bearing should be press-fitted using a flat press. The use of centring or calibrating pins can cause damage to the bearings and lead to greater clarity.
