Normally a suitable axial securement is required. The bearing rings of a locating bear-ing should be axially located onboth sides. The bearing rings generally have an interference fit and are usually supported onone side by a shaft or housing shoulder. Inner rings are axial- ly secured onthe side opposite the shoulder by• a plate screwed to the shaft end ( âž” fig ).Outer rings are generally retained bythe cover of the housing bore ( âž” fig , page 37 ).It should be observed that with bear-ings of series GEP ( âž” fig ).For non-locating bearings the outerring (which normally has a tight fit) should be axially located; the inner ring must be free to move axially on the shaft ( âž” fig ), whichhave a radially split outer ring, expan- sion forces will be produced under purely radial load; the axial compon- ents of these forces will act on the housing cover. The axial load acting on the cover may be as much as 30 % of the radial load. This must be taken into account when dimensioning the hous- ing cover and selecting the size and number of the attachment screws. If shaft and/or housing shoulders areundesirable because of manufacturing or assembly considerations, spacer sleeves or rings can be inserted be- tween the bearing ring which is to be located and an adjacent machine com- ponent (
