The Revvo Caster Company Inc. has introduced its new ET Series casters designed to move moderate loads via manual propulsion. Four-inch (100-mm) diameter swivel models are available with an optional fixed-position brake that mounts to the top plate so that the brake is always in the same easy-to-access position regardless of which way the swivel wheel is facing. The fixed-position brake is ideally suited for grocery roll pallets that lock inside of trucks; however, ET Series casters are also designed for point-of-sale displays, warehouse racks, medical and hospital carts, and mobile appliances, A/V equipment and other mobile products used in commercial, institutional, and industrial facilities, according to Revvo Caster.
New ET Series swivel models feature a double-ball raceway for smooth directional movement with the capability to withstand shock loading, Revvo Caster states. Fixed and swivel models are available in wheel sizes of 100 mm (4 inches) and 125 mm (5 inches) diameter with load capacities ranging from 120 to 250 kg (264 to 550 lbs.). Wheel types include polyurethane-on-nylon with roller bearings, and black nylon or blue rubber with precision ball bearings. Fixed models have an oblong top plate. Swivel models are available with either a special top plate for the fixed-position brake (100-mm/4-inch-diameter models only) or a standard top plate. Accessories include wheel locks for standard swivel models and thread guards to prevent debris from binding the wheel.
