ABSTRACT:
A one-piece replacement sleeve is provided for installation on a conveyor belt roller to prolong the roller's wear life. The cylindrical, split sleeve has a central bore to receive the roller and circumferential grooves in the outer surface to receive fastening circlets to fasten the sleeve to the roller. The sleeve has two radial slits oppositely disposed and extending axially along the entire length of the sleeve to facilitate easy installation and replacement of the sleeve. The slits allow the sleeve to be installed on the roller without the need to remove the roller from its journal mountings. The slits also allow the worn sleeve to be quickly and easily removed by cutting or otherwise removing the fastening circlets. Since the sleeve is formed of one piece of material, the sleeve wears concentrically, reducing vibrations in the conveyor belt assembly. The sleeve provides significant improvements over roller discs and two-piece roller sleeves in the prior art.
