Abstract
A belt tightening assembly for conveyor systems includes an elongated outer tube and an inner tube sized to be complementarily received in the outer tube. The inner tube retractably extends out of the outer tube to varying lengths. A bearing housing extends from a long end of the inner tube and is integrated with the inner tube such that the inner tube and bearing housing do not separate from each other during normal operation. A spherical bearing is inserted into the bearing housing, the belt tightener is secured to a roller of a conveyor system, and the assembly is secured to a side of a conveyor. A separate pillow block is not used, eliminating a number of collection points for contamination and lowering costs. Also, not requiring a pillow block to be fastened to the inner tube reduces shear forces that result from imprecise fastening.
