Q Antistatic Urethane (OCTRON) Wheel Properties- Because of the 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 widevoltage range.

- Due to lower hardness than ordinary urethane wheels (shore A67),vibration and noise on grating oor decreases.- Because carbon black is not used, there is no contamination to the oor or dispersion of carbon to products.

Vibration Insulating Casters

WorkpieceQ Yield problems expected with the conventional wheels(1) Particulate generation of a conveyor machine due to vibration transmissionWhen work is being conveyed into a clean room, casters are travelling over steps or gratingsurfaces and vibrations from the oor are transmitted to the cart. Vibrations not only causedusts from the casters and the cart but possibly transmitting impacts on important work.(2) Particles generated due to vibrations

Vibrations by casters traveling lift dusts around the oor surface and down ow air system maynot be able to control the particle amounts.(3) Anti-static CountermeasuresDusts adhering to the rubber / urethane wheels of conventional casters,which accumulates staticelectricitygeneratedby frictionbetweenwheelsandthe oor andmay causea sparkdischarge.

Q Particulate Generation Comparison

Q Effect of Vibration Absorption

Q Feature of VibrationDampers-Protects transported equipment byabsorbing and damping vibrations fromthe oor .

-Controls particulate generation causedby vibrations, and improves productionyields.

-Prevents static electricity from generatedby the oor with antistatic wheels.

Vibration Absorption

Antistatic WheelsQ Basic Structure of Vibration DamperThe damper is of a double layer structure of a spring within a viscoelasticmember. Shocks received by the caster while going over stepped terrain areabsorbed by the spring,then dampened by the viscoelastic member.New mechanism provides solutions for conventionalspring-loaded casters withinsufcient vibration damping, and urethane type with degradation-inducingdurability losses.Also excellent in safety with no damping gas leaks.
