Bearings and energy supply systems for car interiors

Move seat elements, rotary switches, doors and windows safely and without maintenance

When designing the vehicle interior, safety and comfort play a major role. Bearing points and cable guides in the interior components should therefore be as quiet and smooth-running as possible. We offer the right product for various mechanical and electrical interior applications and will be happy to help you select the right product.

Advantages of our e-chains

Cost-effective
Lightweight

Easy to install
High, predictable service life
Customisable to weight and load limits
Certified according to IATF 16949

Advantages of our bearing technology

Lubrication-free and therefore maintenance-free
Quiet operation
Cost advantage and up to 80% weight saving compared to metallic solutions
Temperature-resistant up to 120°C
Low fogging (more on this in the blog)
Suitable for e-coating and self-calibrating plain bearings
Ideally suited in combination with plastic shafts
High, predictable service life
Certified according to IATF 16949
