Tente ESD swivel caster 160 mm with total lock, top plate 137 x 105 mm

Anyone fitting out trolleys, chassis or shelf units for the ESD protected area needs casters that do not electrically isolate the structure and that can be locked reliably at assembly and test positions. This swivel caster has a wheel diameter of 160 mm, an electrically conductive tread of black solid rubber and a trailing total lock. It is fitted with a bolt-on top plate with a mounting dimension of 137 x 105 mm.

Benefits

• Tread of electrically conductive solid rubber, so the structure stays tied into the grounding path through the caster instead of acting as an insulator.
• The trailing total lock blocks the wheel and the swivel head, so the trolley holds its position during loading and testing.
• Sheet steel wheel centre with a bolted axle, so the caster can be taken apart instead of being replaced as a riveted unit.
• Swivel head with a double ball race and swivel head guard keeps steering easy and keeps the race covered.
• Roller bearing in the wheel, making the trolley easier to start under load than with a plain bearing.
• Sheet steel housing, bright zinc-plated and blue passivated, intended for dry indoor use.
• The top plate 137 x 105 mm bolts flat onto the frame and transfers the load across the whole plate.

Application

Typical use is on transport and material trolleys, chassis, shelf trucks and workbenches inside an EPA, wherever populated assemblies are moved and the whole structure has to stay electrostatically controlled. At 160 mm wheel diameter the caster also runs over floor joints and door sills, and the total lock keeps the trolley in place at handover and test positions. 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.
