Rotating shafts are held in alignment by bearings, which are usually a close fit on the shaft and are themselves located in bearing housings.  The bearing is also a close fit in its housing, and relative movement should not occur.  However, this is not always the case, and bearing housings often become worn.

A warped shaft, or vibration, for example, can cause movement of the bearing and wearing of the housing.  Lack of lubrication often causes bearing seizure and its rotation in the housing.  Pulsing, or unsteady shaft loading, may also cause movement of the bearing in its housing and consequent wear.

To avoid poor machine performance it is important that such wear is rectified as soon as possible.  There are various alternatives which may be considered.

Replacing the worn housing with a totally new component can be expensive, as well as time consuming while waiting for delivery.  Stripping down and refitting can also be a major operation, as quite often, bearing housings are located in the main body, or in a major structural component of the machine.

Machining out the housing and fitting a larger bearing is another alternative, but this can be a complicated procedure.  Indeed, machining the housing may be impossible due to the size and complexity of the component.

Rebuilding the housing by welding is an alternative which includes all the problems of machining as well as possible welding difficulties.  Some materials do not lend themselves to successful welding.  Also hard spots within the weld may hinder subsequent machining.

Belzona® 1111 (Super Metal) overcomes all the major problems of such repairs, and at a fraction of the cost.  Watch the attached video to gain a better understanding of how to perform this application.

Let us teach you how to perform these repairs to your machinery and equipment.
