Conveyor rollers

Tubes made of plastic, steel or stainless steel

It is hard to imagine conveyor technology without conveyor rollers. We offer numerous variants made of plastic, steel and stainless steel – ball bearings with one or two rows of balls (TR0) or with cone ball bearings (TR1). Both variants are convincing due to their very smooth running and are ideally suited for gravity drive. In addition, we offer idlers with deep groove ball bearings according to DIN 625 (TR2) for heavy loads, such as the transport of pallets. These conveyor rollers are available with drive (sprocket, toothed belt, …) or without drive. For this type, deep groove ball bearings are either pressed into the tube or welded to it using circular blanks – depending on the application and load.

Load capacities between 10 and 495 kg
Pipe diameters from 20 to 108 mm
Shaft ends with internal thread (IGM), external thread (AGW), two smooth milled sides (SW) or without machining (smooth)

Product data sheet

The advantages at a glance

Individual design and production exclusively for you and your requirements or purpose
Idler tubes made of plastic, steel and stainless steel
TR0: Idler bearings with non-lubricated rows of balls for very smooth running, e.g. for gravity operation
TR1: Idler bearing with oiled conical ball bearings, also very smooth running, but with a significantly higher load capacity
TR2: Idler bearing with greased deep groove ball bearings, for heavy and driven use
Shaft ends optionally with internal thread, external thread, spanner flat, smooth, rigid or with spring
Numerous options, such as PVC coating, grooves for drive belts, single and double sprockets, electrogalvanized surfaces and much more.
Special designs on request

Idler with single chain wheel for roller conveyors with tangential drive
Idler with double chain wheel for roller conveyors with roller to roller drive
Sprocket sizes in 1/2 x 5/16″, 5/8 x 3/8″, 3/4 x 7/16

Shaft ends – Variants

Depending on the construction of the roller conveyor frame, our support rollers can be machined with different axle ends.

In the case of side profiles with holes, the idler roller is screwed tightly via an internal thread. For slots, on the other hand, an external thread is often used, in which case the idlers are also firmly connected with nuts. Such a fixed connection is advisable if the conveyor rollers are to carry heavy loads and the maximum load capacity is to be exhausted.
With conveyor rollers that are inserted loosely, the maximum load capacity is no longer given. For medium-heavy or light materials to be conveyed, these conveyor rollers are sufficient and can be provided with a spanner width, a smooth axle end in rigid design or with a spring.

Options

Electrogalvanized surface
One or more depressed groove(s)
PVC coating as shrink hose
Flanges in bolted or welded form
Conical push-on parts for use in curves
Welded blanks instead of pressed-in bearing caps for particularly robust operation
