| Purpose-built design
The Interroll Motorised Pulley has been specifically designed for belt conveyors.
Totally enclosed
The motor, gearbox and bearings are totally enclosed and sealed inside a steel shell; therefore they are unlikely to fail due to harmful environmental conditions such as water,
dust, grit, chemicals, grease, oil, etc.
Space saving design
Because the drive unit and the bearings are mounted inside the Motorised Pulley shell, it takes up much less room than a conventional drive. No need for costly extras like chains,
v-belts, couplings, bearings, support structure and special guarding.
Safety
The Interroll Motorised Pulley is probably one of the safest drives available because the motor is completely enclosed and the external shafts are always sta-tionary. The only
moving external parts are the Motorised Pulley shell.

Low purchasing and installation cost
The Interroll Motorised Pulley is quite often less expensive than a conventional drive because it has fewer parts, which reduces conveyor design and purchasing costs. It is also
much quicker and easier to install - certainly less than a quarter of the time needed to fit an exposed sys-tem.
Low maintenance cost
The end user also benefits from the Interroll Motorised Pulley, because it requires no maintenance other than the recommended oil change every 10.000 hours. In other words, there
are almost 5 years between oil changes based on an 8-hour/day 5-day working week.
Efficiency
The Interroll Motorised Pulley usually has a much higher efficiency from electrical motor to shell (pulley face) than conventional drives, because it has fewer frictional losses,
and therefore efficiencies of up to 97% can be achieved.
Cleanliness
Because the Interroll Motorised Pulley is totally enclosed, it cannot contaminate any conveying materials such as electrical components; plastics and other materials that must be
kept perfectly clean durin.
Aesthetic appearance
If installed correctly the Interroll Motorised Pulley always looks good. Due to its compact size and smooth lines, quite often the Motorised Pulley is out of sight, because it is
hidden within the conveyor frame.
Weight saving and distribution
Often the Interroll Motorised Pulley is lighter than conventional drives and often it is possible to reduce the cost of the conveyor structure, because the weight is evenly
distributed within the conveyor frame.
Fewer parts
An Interroll Motorised Pulley consists of the drive and two fixing brackets! Conventional drives can require up to 8 or more separate components, most of which have to be
purchased from different suppliers or manufactured specially.
Low noise
Thanks to the totally sealed enclosure and high quality gears the Interroll Motorised Pulley runs almost at a whisper - a very important fact in today's modern factory
environments.
