A fundamental prerequisite for the correct functioning of GLYCODUR® bearings in daily operation is cleanliness and care when installing. The housing and other components of the bearings should be cleaned and deburred before installation. Unmachined surfaces on the inside of cast housings should be free of moulding sand before installation.
The preferred way to install GLYCODUR® bushings and flange bushings is to use a mandrel (see ). By using an O-ring the bearing can be easily hold on the mandrel. The installation is made easier if a small amount of oil or grease is used on the bearing seat.
Installation with Mandrel
When installing larger bushings we advice the use of mounting rings (see ), the use of which aligns and centers the bushing which, furthermore, cannot tilt during insertion. Using a solid lubricating paste containing molybdenum disulfide (MoS2) can reduce scuffing tendencies and lower the insertion force. Bushings and flange bushings which will be subjected to very high loads during operation should be mounted with the joint positioning 90° to the loaded area so that the service life is not reduced.
GLYCODUR® bearings can also be fixed by gluing in or on the housing. It must be guaranteed that the adhesive can withstand the anticipated operating temperatures and meets the requirements with regard to expansion, strength and tempering. If there is no operational experience, it is recommended to contact the manufacturers of the adhesive directly. When using adhesives, care must be taken that none comes into contact with the sliding surface.
Furthermore, the mating surface must be cleanead and checked for damage prior to installation. When inserting the shaft into the bearing care must be taken that the sliding surface is not damaged by sharp edges or burrs, etc.
When mounting thrust washers it is important that they are positioned the correct way around, i.e. steel back against the housing wall.
Installation with Mandrel and Mounting Ring
Calculated for a steel ring DG/D = 1.5 dry pressed in. Ratio bushing width to bushing inner diameter 1 (B/d = 1). In case of deviating bushing widths, the insertion force will be determined by multiplication with the new B/d ratio.
