Premier Tech Chronos transportation chain driven live roller (CDLR) conveyors are constructed with welded frames consisting of 7ga formed steel rails and structural steel cross members. Rollers are 2-1/2” diameter tubing with welded sprockets, 11/16” spring-loaded hexagon thru-axles, precision bearings are pressed in and swedged. Rollers will be equally spaced on 3 1/4", 4", or 6” centers, with every roller being driven with individual chain loops. The roller to roller chain drives are fully enclosed in an 11ga chain guard. Standard hollow shaft Dodge Tigear 2 reducers and Baldor motors are shaft mounted to the CDLR’s drive roller.
