TPA – Wheel and caster series
Light duty wheels and casters with thermoplastic rubber tread and polypropylene wheel center
The tread of the wheels and casters in the TPA series is made from a high-quality thermoplastic rubber-elastomer. This has a hardness of 75 Shore A and is cast onto a polypropylene wheel center. The tread is non-marking and forms a strong, unbreakable bond with the wheel center. The TPA series is characterised by very low rolling and swivel resistance.
TPA wheels and casters are frequently used in retail facilities and display stands. They are also used for medical equipment, measurement and testing equipment and work and assembly stations.

TPA – Wheels
The wheels in the TPA series come in sizes ranging between 2 and 8 inch as standard and are combined with a ball bearing or plain bore. Electrically conductive wheels in non-marking gray and wheels with ball bearing seals are also available.
