LKF - Bearing Housing

It is a well known fact that the calculated life expectancy of a rolling bearing presupposes that its comparatively thin rings will be fitted in housing that are as true as modern machine shop techniques can make. It follows that defective bearing seat in the housing and incorrect housing fit can cause bearing failure. LKF Bearing Housing offer you protection against these failures and many more. The bearing seating of the housing is machined to tolerances so that a perfect fit of the bearing outer ring is ensured and in most cases the seating width is such that the bearing has axial freedom. Thus dimensional inaccuracy, slight positioning error in mounting and thermal elongation of the shaft can be accommodated in the housing itself. Axial location of the bearing is achieved by employing locating rings. Apart from these advantages, LKF also covers a wide range of bearing housings providing a high degree of flexibility as regards selection of bearings and methods of mounting them. A choice of seals and methods of lubrication makes these suitable for diverse fields of application.
