Compact and Lightweight Conveyor Belt Drives

Saves Space
The Rulmeca Motorized Pulley encloses its motor, gearbox, and bearings within a hermetically-sealed, oil-filled pulley shell, making it a very compact and lightweight conveyor drive system. This is a big advantage to operators and manufacturers of mobile crushing & screening plants.

Makes Fabrication Easier
Since the Rulmeca Motorized Pulley is compact, lightweight, and pre-aligned, installation is quick and easy. Setting the drive only requires four bolts and electrical termination. Installation time is usually 1 to 2 hours. Heavy external gearboxes and motor frames, as well as guarding around rotating shafts, are eliminated.

Improves Conveyor Reliability
Hermetic seals and a continuous oil bath of all bearings and gears insure that the Rulmeca conveyor drive provides consistent “up time” in spite of harsh ambient conditions. The system prevents dust and grit from entering the drive and contaminating the moving parts.

Increases Conveyor Drive Operating Life
The Rulmeca internally-powered conveyor drive extends drive life because it eliminates the need to maintain external pillow block bearings, external shafts & couplings, external motor fans & cowlings. Continuous oil lubrication is automatic.

Lowers Maintenance Expense
Since the Rulmeca Motorized Pulley does not use external bearings, which require greasing and inspection, but rather encloses all mechanical parts within an oil-filled shell, it reduces maintenance requirements to a fraction of what exposed drive systems require.

Improves Personnel Safety
Enclosing all moving mechanical parts within a pulley shell, enables the Rulmeca Motorized Pulley to protect plant personnel from pinch points as well as slip, trip, and fall hazards. The drive eliminates the need for expanded metal guarding around rotating shafts, external gearboxes, motors, and cooling fans.
