Abstract
A linear motion guide unit is disclosed in which there is provided a retainer band making it possible to easily fit a roller chain with rollers traveling through a recirculation circuit into a load way of the recirculation circuit, thereby making sure of smooth recirculation of the roller chain. Cooperation of the retainer band with a retainer plate helps guide links of the roller chain in a load way of the recirculation circuit, keeping the roller chain against running out of the load way thereby ensuring smooth movement of the roller chain throughout the recirculation circuit.
Claims12
A linear motion guide unit comprising;
- an elongated guide rail, a slider arranged on the guide rail for movement relative to the guide rail, a rolling element rolling through a recirculation circuit made in the slider, a rolling-element chain allowed to travel together with the rolling element through the recirculation circuit, and a first retainer band to guide the rolling-element chain along a load area in the recirculation circuit defined between the guide rail and the slider while keeping the rolling-element chain against running out of line;
- and wherein the first retainer band is installed in the slider in a detachable way allowing the rolling-element chain to fit it into the recirculation circuit from the load area of the recirculation circuit.
