O-Ring Belts & Pulleys
The elastic nature of o-ring belts allows them to apply tension on the pulleys when stretched and the rubber construction creates excellent grip characteristics between the pulley and belt. O-Ring belts and pulleys can be used in a variety of applications including follow focus systems, linear drives, 90 degree drives, XY tables, robot tracks, battery hold-downs, etc. A low stretch factor will apply a small amount of side-load to the axles and create less friction while a higher selected stretch factor will apply slightly more side-load to the axles and have more resistance to belt deflection.
