Series 3500

Application area

Driven unit handling conveying, such as transport of cardboards, containers, barrels or tires.


The use of polyamide drive heads results in very quiet running.

Lateral loading

The tube ends are rounded, thereby allowing materials to be easily moved on from the side. Axial forces are removed through ball bearings and seals.

Robust construction

An axial fixation of the bearing assembly (bearing housing, ball bearing, seal) on the non-drive side can be accomplished in several ways. For the design with steel tube, the bearing assembly is pressed into the tube and then flanged. For the design with PVC tube, it is fitted with a groove inside the tube in which the press-in edge of the bearing housing engages. For the designs with PolyVee and round belt, the drive bearing assembly is also pressed into the tube and then flanged.

Modular construction

With a permanently installed bearing housing for a tube diameter of 50 and 60 mm, insertable polyamide drive heads, such as sprocket, toothed belt and flat belt heads, are interchangeable and can also be exchanged with friction heads. Numerous drive versions are available with flat, PolyVee, round or toothed belts as well as chains.

  • Round belt drive head
    With the round belt drive head, the drive section is separated from the conveying section, so that materials cannot be shifted due to batching belts. Since the drive head has a higher friction because of grooves in the metal tube, the result is a higher conveyance of the round belts. If the round belts should slip because of the application, then the wear of the belts on a round belt drive head is higher.

  • PolyVee drive head
    The nine grooves of the drive head allow the use of 2-rib, 3-rib or 4-rib PolyVee belts. Compared with a round belt, the use of a 2-rib belt allows transferring approximately twice the torque.
