Abstract
Greasable idler pulleys and related kits and methods are disclosed. The greasable idler pulley has a rotating body, a bearing, to enable the rotating body to rotate with respect to a shaft, and grease fitting defined through the rotating body. The rotating body may have a bearing seal cap having an orifice and a rotator. The grease fitting may be in fluid communication with the bearing through the orifice in the bearing seal cap. Kits are also contemplated, such as a kit for retrofitting a non-regreasable idler pulley including a rotator to a regreasable idler pulley. Methods may include methods of producing a regreasable idler pulley from a non-regreasable idler pulley.
