الوصف

This E.R. Wagner plate caster has a polyurethane on aluminum wheel, a flat base with holes for bolting or welding to an object, and a swivel design to allow movement with a 360-degree change in direction. A total-lock brake simultaneously prevents rolling and restricts swivel movement when the foot-operated lever is depressed. The plate caster's wheel consists of a polyurethane tread molded and mechanically locked to an aluminum core. The wheel rolls with ease, resists abrasion and impact, provides quiet operation, and protects floors. The tread is non-marking and has a hardness of 50 to 60 Shore D. This wheel is suitable for bearing medium to heavy loads on carpeted and hard-surfaced floors. The wheel has a recommended operating temperature range of -20 to 180 degrees F. The roller bearing provides high load capacity and greater durability than ball bearings.Plate casters are wheeled mechanisms used to support and maneuver objects such as carts, racks, and dollies. Plate casters are named for their mounting system: they have a flat plate, usually with four bolt holes, that forms the top of the caster and attaches to the object. Plate casters vary in their maneuverability. Some are rigid and only roll at a fixed angle, while other casters swivel to allow a 360-degree change in direction. Plate casters may have brakes, and swivel casters may have locks to set them to a fixed angle. Casters may have single or twin (dual) wheels made from a variety of materials. Generally, wheels with hard tread material have a higher load capacity and roll easier than soft tread wheels, which provide quieter operation and cushioning. Load capacity for plate casters is also affected by tread width and wheel diameter. Plate casters are used on furniture, carts, shelving, appliances, scrap bins, production dollies, and utility trucks for material handling applications in a variety of industries. E.R. Wagner manufactures casters, wheels, hinges, stampings, and tubular products. The company, founded in 1900, is headquartered in Milwaukee, WI.
