A lubricant pump is provided comprising a plain cylindrical driveshaft on which is arranged a shaft collar formed with a plain cylindrical bore embracing the driveshaft. A spring is attached to the collar and extends to an anchor point on the sewing machine frame to bias the collar against the driveshaft. The spring displaces the collar arranging the collar bore eccentrically with respect to the driveshaft. An oil inlet port is formed in the collar leading to a point on the collar bore which is urged away from the driveshaft by the spring, and a lubricant outlet bore is formed in the bushing leading to the point on the bushing bore which is closest to the surface of the driveshaft in response to the pressure of the spring.
