ESD swivel castor 100 mm with total lock, top plate 105 x 85 mm

A parked trolley in an ESD protected area has to stay where it was left, even when someone bumps into it. This swivel castor therefore carries a trailing total lock that blocks wheel and swivel head at once, and otherwise runs on a 100 mm electrically conductive solid rubber wheel.

Benefits

• Wheel diameter of 100 mm keeps the force at the push handle low and lets the trolley run over joints and cable ramps.
• Trailing total lock, one step blocks wheel and swivel head together, so the parked trolley neither rolls nor swivels away.
• Black solid rubber tread, electrically conductive, so the discharge path from trolley through castor to floor stays intact.
• Steel sheet wheel centre with a bolted wheel axle, the castor can be checked on the trolley and taken apart if needed.
• Swivel head with a double ball race, the castor lines up with the direction of travel on small steering inputs.
• Pressed steel housing, bright zinc plated and blue passivated, which stands up to moisture and corrosion in shift operation.
• Swivel head guard keeps threads, chips and film residue out of the ball race.
• Top plate fitting with a 105 x 85 mm bolt hole pattern, so the castor replaces existing castors of the same pattern without reworking the frame.

Application

The castor is used on assembly, supply and test trolleys that have to stand safely at their workplace, for example during placement, measurement or repair. Two castors with total lock on one side of the trolley and two castors without a brake on the other are the usual arrangement. The range covers further wheel diameters.
