33 × 9 mm Polyurethane guide roller with solid aluminium core – 70 kg, ball bearing

The polyurethane guide roller 33 × 9 mm is a compact precision wheel for guiding and replacement applications. Despite its small size, it carries up to 70 kg per wheel and runs particularly smoothly thanks to the grooved ball bearing.

Solid aluminium core machined from solid material: The wheel body is manufactured from solid aluminium round stock by machining – not hollow-cast, not formed from sheet metal. This creates a torsionally rigid, dimensionally stable wheel body with significantly lower dead weight than comparable steel or cast wheels. Ideal where rolling masses are to be minimised (handling systems, machine trolleys, ergonomic transport).

Material: polyurethane tread, hard-wearing and dirt-repellent. Hardness: approx. 92° Shore A. Tread yellow, non-marking and floor-friendly.
