Material: Fork: steel plate, zinc-plated.
Tread: thermoplastic rubber TPE, grey, electrical conductive and antistatic (104 Ω).
Wheel body: plastic, screwed.
Wheel mounting: ball bearing.
Swivel bearing: double ball wreath.

For indoor use. Low-noise operation with low rolling and swivelling resistance. Non-marking. The tread is slightly oily and can cause contact discolouration on sensitive surfaces.

Temperature range: -20°C to +60°C.

Note to electrical Antistatic and Conductivity: Wheels and castors are considered electrically antistatic, if the ohmic resistance is 107 Ω or less. Wheels and castors are considered electrically conductive, if the ohmic resistance is 104 Ω or less, even less than parts named antistatic. So, the parts which are named electrically conductive are also antistatic.
