Tente ESD swivel caster 75 mm with total lock brake, bolt hole 10 mm

Anyone fitting out trolleys, chassis or shelf carts for the ESD protected area needs casters that keep the structure tied into the grounding path and that stay put while work is going on. This swivel caster runs on a wheel of 75 mm diameter, the wheel centre is electrically conductive polyamide and the tread is moulded polyurethane. It is fitted through a central bolt hole with a mounting dimension of 10 mm.

Benefits

• Wheel centre of electrically conductive polyamide, so the structure stays tied into the grounding path through the caster instead of acting as an insulator.
• Tread of moulded polyurethane, firmly bonded to the wheel centre and gentle on the shop floor.
• Precision ball bearing in the wheel, a loaded trolley can be pushed with little effort.
• Swivel head with a precision ball bearing, the caster turns in easily and follows the pushing direction.
• Thread guard on the wheel keeps threads, strapping remnants and chips out of the bearing.
• Polyamide housing, a light design without paintwork that could chip off.
• The trailing total lock blocks wheel and swivel head at the same time, so the trolley holds its position at handover and test stations.
• Central bolt hole with a mounting dimension of 10 mm for chassis designed for a single bolt fixing rather than a top plate.

Application

Typical use is on transport and shelf trolleys, material carts, chassis and workbenches inside an EPA, wherever populated assemblies are moved and the complete structure has to stay electrostatically controlled. The total lock is needed at handover, test and packing stations where the trolley must neither roll nor swivel during work. The range is supplied in the wheel diameters 75, 100 and 125 mm, so the casters of one chassis can be matched to a common overall height.
