Tente ESD swivel caster 50 mm with brake, 11 mm bolt hole

Anyone fitting out a trolley, a shelf unit or a workbench for the ESD protected area needs casters that do not electrically isolate the structure and that stay put during loading and unloading. This swivel caster has a 50 mm wheel, a wheel centre of electrically conductive polypropylene and a wheel brake. It is fitted through an 11 mm bolt hole, which according to the supplier takes standard screws of any length.

Benefits

• Wheel centre of electrically conductive polypropylene, so the trolley stays tied into the grounding path through the caster instead of acting as an insulator.
• Tread of TENTEprene, a thermoplastic rubber in grey, non-marking and therefore free of abrasion streaks on light-coloured shop floors.
• The wheel brake blocks the wheel, so the structure holds its position during loading and testing.
• Swivel head with a double ball race keeps steering easy even when the trolley is pushed from the side.
• Sheet steel housing, bright zinc-plated and blue passivated, intended for dry indoor use.
• The 11 mm bolt hole takes standard screws of any length, so the caster also fits frames of unusual material thickness.
• The small 50 mm wheel keeps the overall height low, which matters on under-bench trolleys, roll stands and flat small-parts carts.

Application

Typical use is on transport and shelf trolleys, material carts, workbenches and chassis inside an EPA, wherever populated assemblies are moved and the whole structure has to stay electrostatically controlled. The brake is needed at handover and test positions where the trolley must not roll away during work. The range is also supplied in further wheel diameters, so swivel and fixed casters on one chassis can be matched to the same overall height.
