Введение продукции

This cleanroom caster wheel combines a deep blue-gray conductive TPU tread with a corrosion-resistant stainless steel swivel fork, top plate and axle hardware. The resilient tread rolls quietly and limits visible floor marking while the dark hub and sealed bearing interface keep the assembly compact. A square plate with four mounting holes spreads attachment loads into the equipment base, and the single side pedal provides an accessible wheel-braking interface. The swivel race is positioned directly beneath the plate to maintain maneuverability without an offset stem. Wheel diameter, load capacity, electrical resistance, plate pattern and brake function are selected for the actual cabinet, trolley or mobile process equipment rather than inferred from wheel color alone.

Основные характеристики

The conductive non-marking TPU tread combines resilient floor contact with a wear-resistant rolling surface suited to smooth controlled-area floors.

Satin stainless steel fork, top plate and axle components provide a cleanable exterior with fewer painted surfaces exposed to routine wipe-downs.

The square top plate uses four separated corner holes to distribute mounting force and resist twisting at the equipment base.

One side-mounted foot pedal places the brake control beside the wheel while retaining clear access to the axle and swivel bearing interfaces.

Обеспокоенность клиентов продуктами

A caster that rolls smoothly in a workshop can still mark a controlled-area floor, accumulate charge, corrode during cleaning or loosen under a mismatched mounting pattern.

A hard or unsuitable tread can leave visible tracks, transmit vibration to instruments or damage resin flooring at small contact patches.A resilient non-marking TPU tread is selected with wheel diameter, hardness and load per caster matched to the floor finish and equipment mass.

Electrical charge can remain on mobile equipment when the wheel compound and floor path do not provide the intended dissipation route.Conductive tread formulation, hub-to-axle continuity and the installed floor system are evaluated together, with electrical resistance verified for the required application.

Painted or carbon-steel fork components may develop surface damage after repeated detergent wipe-downs or humid service.Stainless steel external hardware and an accessible open fork geometry reduce coating dependence and simplify visual cleaning checks.

An incorrect top-plate pattern, mounting height or brake sweep can interfere with the equipment base or produce unstable tracking.Plate size, four-hole centers, overall height, swivel radius, wheel width and pedal clearance are matched to the existing mounting envelope before installation.
