The Schaefer Motor Roller (SMR) is a development of SSI Schaefer.

Conveyors with SMR drive are used for short sections, inclined roller conveyors, curves and gates.

The drive of an SMR conveyor is based on a direct current motor integrated into the conveyor roller. Power transmission to adjacent rollers is carried out by Poly-V belts.

Control:

The SMR units have a decentralised control; the SMR is controlled by the "Quatronic" unit developed by SSI Schaefer. One Quatronic unit may control up to 4 SMR.

Supply:

The power supply is carried out via a decentralised mains power unit mounted under the roller conveyor.

The use of the Schaefer Motor Roller offers the following advantages:

• zero-pressure conveying
• decentralised control
• low construction height
• flexible application thanks to simple modular design
• possibility of speed adjustment of the SRM roller
