A new sealed belt drive features a new sealing method designed to keep dirt and debris at bay. A stainless steel band runs across the length of the beam, which is held in place by a magnetic strip. The band and strip effectively enclose the linear motion system, minimizing the entrance of dirt and debris. The unit is offered in standard and cleanroom configurations, in 80 and 100 mm beam widths, and in single beam lengths to 6 m. Longer beam units can be created by joining. Load capacity is 408 lbs and 1,002 lbs for the 80 and 100 mm beams, respectively. It is equipped with high-capacity LBG re-circulating ball guides.
