ABSTRACT:
A linear bearing structure comprises a bearing bush, a plurality of annular ball retainers each holding a plurality of bearing balls, circumferentially and a pair of annular endpieces respectively removably secured to ends of the bush to confine the ball retainers therein. The bearing bush comprises an outer metal cylinder and an inner cylindrical lining layer formed by a bearing material having a small coefficient of friction and a small coefficient of wear and is provided with a slit which has a predetermined width and extends along the axis of the bush over the entire length thereof so that the bush can be circumferentially elastically compressed by a magnitude corresponding to the width of the slit. Each of the endpieces has, at the inner side thereof, an annular groove having a diameter smaller than that of the bush so that by compressing the bush into the annular grooves of the endpieces at the ends of the bush, the bush and the endpieces can be elastically fitted together.
