Specifications/Overview

■Antistatic Urethane (OCTRON) Wheel Properties

·Because of an antistatic effect, sparks and high-frequency noises are prevented.

·Conventional anti-static caster wheels may exhibit varying electrical resistivity depending on measured location on wheels,
but the OCTRON urethane wheels have uniform resistivity regardless of the measured location, being effective in a wide voltage range.

·Due to lower in hardness than ordinary urethane wheels (shore A67), vibrations and noises on a grating floor have decreased.

·Because a carbon black is not used, there is no contamination to a floor nor dispersion of a carbon to products.
