To obtain the best performance, certain basic rules should be observed in the installation.

Keep Parts Clean

The clearance involved between the balls and tracks is very small and so any dirt particles present in the area of the tracks cause rough, noisy rotation and perhaps even permanent damage.

Keep Components Round

The inner and outer rings are generally of fairly thin section and no mating parts must be of good roundness to prevent distortion of the rings with consequent inaccurate rotation and roughness.

Keep Assemblies Shockfree

Since radial loads are supported on several contact points, shock loading can result in permanent deformation of the tracks and balls. The resulting craters again give rough, noisy rotation.
