Castors
Castors and wheels are components that attach to a wide range of equipment to make them mobile. Examples include, trolley castors, platforms, cabinets, workbenches and other transportation equipment. They are bought to replace existing castors or added as a new component to turn stationary equipment into a mobile unit.The ...castor's bracket or housing can be Fixed (Rigid) or Swivelling.
Fixed castor brackets can only move in two directions, forwards and backwards. Subsequently, they are described as as straight-line movement.
Swivel castor brackets can swivel the castor wheel 360 degrees. As a results they can move in any direction. Furthermore, they can be lockable with a brake. The brake can be either a wheel lock, Wheel Footbrake or a Swivel & Wheel Brake (also called a Total Stop Brake). Swivel and wheel brakes lock both the wheel and the castor's swivel head. A Wheel lock or a Wheel Footbrake locks the caster wheel only.
We stock a massive range of castor wheels to use in castor frames. Nylon, Polypropylene, Rubber Tyre, Polyurethane and Cast Iron are probably the most popular. Each type of wheel is available with either a smooth plain bore, a roller bearing or ball bearings.

There is double thrust bearing in the swivel head to achieve a high load capacity and maintain castor performance and durability.The role of the spring in an AGV castor is different to that of a standard shock absorbing castor. In a standard shock absorbing castor, the spring absorbs shock and noise whereas, it's role in a AGV castor is primarily to keep the wheels in contact with the floor.When determining the overall height requirement of a shock absorbing AVG, it should be designed based on the spring cushion being fully compressed.The shock absorbing pad made from a special rubber compound absorbs minor shocks and vibrations to protect the AGV unit. There is a 10mm range of compression which helps prevent the castors from losing contact with the floor which may be caused by small floor imperfections. An AGV's castor leaving the floor when changing directions is often the cause of the AGV becoming unbalanced and coming to a stop by straying off its designated path.The Top Plate is 112mm x 112mm and has 4 bolt holes that are spaced 92mm x 92mm, each with a 9mm hole diameterThis castor frame has two wheels with a Polyurethane tyre (Shore A 95) on an Aluminium centre each containing ball bearings, Having a twin wheel castor is great for reducing the effort required to swivel the castor and most efficient by reducing the amount of room the castor needs to turn the AGV Cart.The polyurethane wheel has excellent elasticity the minimises slipping that can happen when an AGV starts or stops. In addition, the elasticity also absorbs small shocks arising from small imperfections in the floor. The wheel itself is non marking and will not damage the floor. - In Stock

The Fixed Bracket has a 4 hole top plate with 80x60mm bolt hole spacing. The load capacity of this castor is 150kg using manual propulsion at 4km/h (walking speed)
The Polyurethane tyre offers a low tractive resistance making it easier to get moving compared with softer rubber tread wheels. It is also a bit softer than hard tread wheels making the castor smoother and quieter running. The polyurethane tyre is also non-marking and gentle on floors while the ball bearing lowers the rolling resistance to reduce the effort required to move the castors. Put this wheel into a strong bracket and you have a castor that is a great choice for the wide range of industrial and domestic applications.</p>
