Roller wear on AT9014-x070 and AT8300-1x00

During operation, the upper rollers [1] and lower rollers [2] of the mover wear out. The suspension strut [3] presses the lower rollers further against the guide rail so that the base body [4] moves outwards and the air gap [5] between the suspension strut and the base body is reduced.

The movers maintain their pretension constantly over a longer period of time, but change their position in the lower to middle tenths of a mm range due to their design. Depending on the requirements, it is necessary to check the position tactilely or visually for changes and to replace the rollers if necessary. If the height position of the mover in relation to the guide rail is only allowed to change within a small range, it is necessary to check the air gap and the position of the mover at short intervals and replace the rollers at an early stage.
