Available in 6.5 and 8.5 in. dia, internally driven Cross Drive has no external moving parts and thereby eliminates possibility of employee injury and/or product contamination. Transfer of power from motor’s drive shaft to drive roller’s outer shell is 96% mechanically efficient, made possible via hardened-steel, precision-cut gear assembly. Latter is housed in sealed conveyor drive roller and connected directly to external motor, eliminating need for chain/sprocket or belt/pulley.
