Careful selection of idler rollers
We develop components for roller-based conveyor systems to optimise your material flow and operational logistics.
Choosing the right support rollers requires a detailed examination of each component, such as the tube, shaft and bearings. Tailoring the materials and design to your application is essential and involves, amongst other things, roller length, tube and shaft dimensions, bearing type, centre distance and conveyor speed.
Configuration with a focus on durability and performance
During the configuration process, it is essential to ensure that the bearings, tubing and axles can withstand the anticipated loads. Technical and environmental requirements, such as electrical conductivity, temperature and humidity, must also be taken into account.

Surface finishing and coating
Further information
ROLLEX offers several types of surface finishing and coating. Depending on the application, you can choose between untreated tubes, electrogalvanised tubes, PVC-coated tubes, rubber-coated tubes, PU-Baytec-coated tubes, epoxy resin-coated tubes and nitrocarburised tubes.
- Untreated: Steel pipe, stainless steel pipe or plastic pipe without any additional surface treatment.
- Galvanisation: Electrolytical corrosion protection with a coating thickness of approx. 0.8 µm.
- PVC coating: Slip-on sleeve for various application requirements.
- Rubber coating: Black NBR rubber coating, bonded and ground to size.
- PU-Baytec: Coating available in various degrees of hardness.
- Nitrocarburising: A thermochemical process for surface hardening.

Coating
Rubber idler rollers
- Rubber coating: The idler roller tube is coated with black NBR rubber, bonded and ground to size. The hardness is approximately 60° Shore.
- PU-Baytec coating: Roller tubes can be coated with PU material in various hardness grades between 70 and 90° Shore.
- Epoxy resin coating: Steel roller tubes can be finished with an epoxy resin coating. The RAL colour number must be specified when ordering.
- Nitrocarburising: A hardening process for surfaces with a maximum penetration depth of 0.2 mm and a surface hardness of up to 540 HV1.
Technical Specifications
Shafts configurations
- Material:
For standard steel applications, ROLLEX uses free-cutting steel in accordance with DIN EN 10277-3 or EN 10278-h, and for stainless steel applications, the material grade 1.4305. - Dimensions:
The design of the conveyor system and the load-bearing capacity of the axle determine the axle dimensions. - Axle slip-on caps:
Made from thermoplastics, these provide corrosion protection and reduce noise levels.

Brake rollers
Brake [support] rollers
Brake rollers – essential for gravity conveyors
ROLLEX enables goods to be slowed down safely and cost-effectively on gravity roller conveyors using direct and indirect braking elements.
Our braking idlers feature a spring-loaded suspension that maintains constant contact with the goods being conveyed, even on slightly uneven surfaces.
Various factors, such as the roller conveyor design, gradient, characteristics of the goods being transported and environmental influences, affect the choice of brake roller type and spacing. Each pallet position requires at least one brake roller to ensure a controlled speed.
Indirect braking is achieved using two support rollers and is particularly suitable when a narrow centre distance is required.
