Standardized aluminium web guide rollers

Aluminium web guide rollers for smooth web handling at high rotational speeds

INOMETA aluminium web guide rollers have proven their performance in industrial applications for many years. Thanks to their well-engineered design, they ensure smooth and reliable start-up – supporting high levels of technical reliability and productivity in applications where web materials need to be guided precisely and transported gently.

We manufacture our aluminium web guide rollers using the INOMETA modular system with prefabricated components. This enables application-specific solutions and short delivery times. Three designs, standard diameters ranging from 60 to 200 mm, lengths of up to 4,800 mm, and a wide range of surface options allow the rollers to be precisely tailored to your application – developed and manufactured in Germany.

For detailed information on our aluminium web guide rollers – from the different designs to all technical specifications – please refer to our brochure.

Applications for aluminium web guide rollers

Aluminium web guide rollers are used for deflection, guiding and transport tasks wherever precise web handling is required. Their low weight and smooth running characteristics make them a cost-effective solution – even for sensitive substrates.

Typical industries include:

  • Modular system with prefabricated components for short delivery times

Which web guide roller is right for your system?

The choice of design primarily depends on the installation situation: Does the roller rotate freely or is it driven? How precisely are the machine walls aligned? The following overview will help you select the right design:

Type BA
Web guide roller with dead shaft
Type BB
Web guide roller with stub shafts
Type BC
Guide roller with journals
Bearing arrangement Internal, continuous rigid axle Internal, rigid axle journals External, in the machine wall
Particularly suitable for Precise web guiding, low-vibration operation, high rotational speeds Compensation for minor axial misalignment, lower weight Driven rollers, robust design

Web guide roller with dead shaft (type BA)

Installation: The roller body rotates while the shaft remains stationary.

The fixed shaft ensures constant and stable movement, enabling precise web guiding and processing. At the same time, it reduces vibrations that can be caused by rotating components, extending the service life of the roller and connected components. Low friction in the bearings results in reduced wear and heat generation while allowing high rotational speeds.

Web guide roller with stub shafts (type BB)

Installation: The roller body rotates while the stub shafts remain stationary.

Type BB offers the same bearing-related advantages as type BA. In addition, it compensates for minor axial misalignment between the machine walls and is lighter than type BA.

Guide roller with journals (type BC)

Design: The journals are permanently connected to the roller body, forming a single unit. They run in bearings that are permanently installed in the machine wall.

The robust design makes type BC the preferred choice for driven rollers.

Surface structure

  • Standard: cylindrical, polished
  • Alternative: application-oriented surface structures, for example, spiral grooved, grooved, concave, convex, structured

Surface coating

  • Standard: Aluminium roller without coating
  • Alternative: application-oriented surface refinements such as hard anodization, PROTEK ceramic, carbide or non-stick coating
