Installation & Maintenance

Sparks Belting motorized pulleys are designed for horizontal installation unless otherwise specified in writing on the order confirmation. Sparks Belting motorized pulleys have identical shaft ends on both sides, so they can be mounted in various positions to suit the conveyor construction.

Motorized Pulley

For motorized pulleys with back-stop the motor must be connected for the correct direction of rotation.

The shaft ends must be mounted in parallel grooves and tightened with a clamp to ensure no axial or rotational movement. Where possible, DURA-DRIVE PLUS mounting brackets should be used.

Minimum width for the mounting brackets should be half the length of the shaft flat.

CAUTION
Make sure serial number and "UP STAMP" on the shaft are positioned upright and are not more than 90° from the horizontal line; otherwise insufficient lubrication will occur.

Other applications for motorized pulleys:
Motorized pulleys can be used for many applications. For example, by machining grooves in the shell or rubber lagging, the motor can be used to drive V-belt and round-belt driven conveyors.

Wheels and sprockets or special profiled lagging can be attached to the shell to drive plastic modular belts or chain conveyors. The DURA-DRIVE PLUS motorized pulley can also be used as a powered brush cleaner by attaching removable brush strips to the shell.
