Optimal running - guide rollers

Each aluminum profile has two own guide rollers, one roller and one guide roller.
These ensure almost wear-free and noiseless operation. They are made of high quality pevolon.
Pevolon is a thermoplastic based on polyamide.
High abrasion resistance, low coefficient of friction and high load capacity are among the properties of our track rollers.
