125mm Top Plate Fixed Castor (Pressed Steel) with 80x60mm Fixing Bolt Hole Centres. Polyurethane Tyre on a Cast Iron Centre Wheel with a 40mm Tread Width and Ball Bearings. Load Capacity = 300kg.
This castor is made from 4mm thick heavy gauge pressed steel. It is a product that is built to last and is great for arduous applications.
The polyurethane elastomer wheel offers excellent elasticity, hardness and resistance to compression. This means that while it has a low rolling resistance it is also gentle on floors and absorbs some of the rolling vibration for user comfort and reduced noise.
