Wheels and castors in the TPA series have a tread of high-quality thermoplastic rubber-elastomer (TPE) and an impact-resistant polypropylene wheel centre. The grey tread with a hardness of 85 Shore A is chemically bonded to the wheel centre. The wheels are non-marking and characterised by low rolling and swivel resistance.
The oil in the tread may cause some discolouration on sensitive surfaces. In such cases, the VPP, POES, POEV oder PATH series can be used as an alternative.
As an alternative to a plate fitting, the TPA series is also available with a bolt hole fitting:
