Heavy duty swivel castors from Tente. Made with polyurethane wheels and an aluminium centre. The castor housing is made from pressed steel. Available in a variety of wheel diameters and with or without brakes.
Polyurethane tyred wheels have high tear strength and abrasion resistance which gives them a life of up to 10 times that of rubber under similar operating conditions. Polyurethane is able to carry loads approaching that of cast iron. Polyurethane has a lower tractive resistance than rubber for the same load so is better for manual handling of very heavy loads. Polyurethane is not affected by greases and mineral oils.
