General description The Rulmeca Motorized Pulley was first produced in 1953 specifically for use on conveyors belt applications. The aim was to produce a compact, hermetically sealed, highly efficient conveyor drive unit that would be unaffected by dust, water, oil, grease or other harmful substances. A Motorized Pulley that would be quick and simple to install and require virtually no maintenance. These aims were achieved and today the Rulmeca Motorized Pulley is considered to be one of the most reliable, effective and safe conveyor drive systems available throughout the world. The Rulmeca...

Sea-dredged aggregates working in wet, salty and aggressive environment! IP66/67 sealing – a MUST – often with re-greasable seals! Recycling application benefiting from IP66/67 sealing systems avoiding internal damage from audio or video cassette tapes and aggressive ambient environments containing air or gas of high Ph-values.

Purpose-built design The Rulmeca Motorized 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 Motorized 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...
