Sufficient cooling fluid should be applied as well to avoid excessive temperatures, as they can destroy the bushing. To facilitate the mounting of small bushings, apply a light coating of oil or grease to the housing bore.

For larger bushings, SKF recommends using a mounting ring fig. If no operational experience is available, SKF recommends contacting an adhesive manufacturer for advice.
In addition, cleanliness, and understanding the causes clussinets premature bearing failure can help too. If composite plain bearings, for example strips, are to be located in a housing using an adhesive, the adhesive should be suitable for the expected operating temperature and should have suitable expansion, aging resistance, strength and curing properties. Care should always be taken when mounting FW bushings not to damage the sliding layer or side faces.
Check that the counter surface shaft seat and other components such as the housing are clean, deburred and that they do not contain any abrasive particles.
Once all the components have been cleaned and checked, the bushing is ready to be installed. SKF also recommends, particularly for larger bushings where more force coussihets required that they be cooled before mounting.
Voussinets also the shaft for sharp edges, burrs or surface defects, which could damage the sliding surface of the bushings. The position of the lubrication groove of solid bronze bushings depends on whether it is an oscillating or rotating or movement and, for the latter, whether oil or grease lubrication is applied fig.

To install bushings, with or without a flange, SKF recommends using a mounting dolly particularly for composite fig. Mounting Skill and care in mounting are prerequisites for long bearing service life.
To facilitate mounting FW busings, the bushing may be split lengthwise into two halves by using a diamond coated grinding wheel.
When cousslnets an adhesive, care should be taken so that no adhesive reaches the sliding surface. Otherwise when the bushing comes in contact with absorbent material it may wick the oil away very quickly. To do this, place an O-ring on the dolly to keep the bushing in position. Then drive the bushing into place with a mechanical or hydraulic press or by tapping the dolly lightly with a hammer. When mounting, thrust washers should be positioned so that the steel backing abuts the housing wall.
