Motion Without Limits® Double Acting Profile Drive Unit The HepcoMotion DAPDU2 unit is built on a robust aluminum beam with two or more carriages running inside. These carriages use the same Herculane® wheels that are in the popular Hepco PDU2 unit and give excellent load capacity and durability with quiet operation. The carriages are driven by a strong, accurate toothed belt and move symmetrically. Units are compatible with HepcoMotion MCS framework system, and with other driven products including the PDU2. Note that the underside of the unit is open, and the correct orientation should be observed to prevent debris ingress. This data sheet gives a brief overview of the product. Other useful information on applications, calculations, etc. is included in Hepco PDU2 and DLS catalogs. Further details may be obtained from Bishop-Wisecarver’s Technical Sales Department. 3D CAD models are available at www.bwc.com.
