To facilitate mounting FW busings, the bushing may be split lengthwise into two halves by using a diamond coated grinding wheel.
Coussinets install bushings, with or without a flange, SKF recommends using a mounting dolly particularly for composite fig. When applying an adhesive, care should be taken so that no adhesive reaches the sliding surface.
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. 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 xkf temperature and should have suitable expansion, aging coussinetss, strength and curing properties.
Sufficient cooling fluid should be applied as well to avoid excessive temperatures, as they can destroy the bushing. Once all the components have been cleaned and checked, the bushing is ready to be installed.

Check also the shaft for sharp edges, burrs or surface defects, which could damage the sliding surface of the bushings. SKF also recommends, particularly for larger bushings where more force is couzsinets that they be cooled before mounting.
To facilitate the mounting of small bushings, apply a light coating of coussinet or grease to the housing bore. In addition, cleanliness, and understanding the causes of premature bearing failure can help too.
The position of the lubrication groove of solid bronze bushings depends on whether it is an coussinfts or rotating or movement and, for the latter, whether oil or grease lubrication is applied fig.
For larger bushings, SKF recommends using a mounting ring fig.
SKF sintered bronze bushings are impregnated with a lubricant and. To do this, place an O-ring on the dolly to keep the coussinfts in position.

Care should always be taken when skd FW bushings not to damage the sliding layer or side faces. Otherwise when the bushing comes in contact with absorbent material it may wick the oil away very quickly. When mounting, thrust washers should be positioned so that the steel backing abuts the housing wall.
If no operational experience is available, SKF recommends contacting an voussinets manufacturer for advice. Imprimer cette page Partager Partager cette page.
Mounting Skill and care in mounting are prerequisites for long bearing service life. Then drive the bushing into place with a mechanical or hydraulic press or by tapping the dolly lightly with a hammer.
