Abstract
Presented is a slide roller apparatus of elegant simplicity, high precision/cost ratio and few parts where the car/track/rollers are relatively movable and the only needed parts (excepting for attachment means). The car is unitary without end caps for the roller groove, the roller groove being machined or otherwise formed into the car with great precision. The ends of the rollers have a sliding engagement with a rail track surface. The tracks and cars may be made of high precision extruded aluminum hard coated and impregnated with a high lubricity material. The rollers preferably are softer than the tracks and may be made of plastic material. The slide roller apparatus has far ranging applications from sail boats to machine tools.
