ABSTRACT:
A bearing for supporting a rotatable shaft is particularly adapted to support a shaft rotating in an arcuate motion that produces a primary wearing portion of the bearing. The bearing structure is a solid block of high molecular weight plastic. A cylindrically shaped bearing bore, adapted to receive a shaft within it, extends between two opposed sides of the block. A plurality of fastener bores symmetrically provide locations for sleeves in the block to receive fasteners for mounting the block to a supporting member in such a manner that the bearing may be dismounted, rotated, and remounted to change the primary wearing portion within the bore. The sleeves are slightly longer than the fastener bores so that the fasteners may be tightened against the sleeves to secure the bearing without deforming the block.
