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.
Keystone Castors & Wheels stock one of the largest ranges in the UK. We have provided quality service to industrial and residential customers since 1923. Whether you need a budget castor for light duty or DIY projects or a premium quality castor for critical applications, Keystone will have the product to suit your needs.

Swivel Castor, 75mm, 140kg Capacity, Nylon Wheel, Plain Bore (MSE075NY)
£6.9675mm Medium Duty Top Plate Swivel Castor. Nylon Wh... Read Moreeel and Plain Bore. Load Capacity = 140kgThis castor has a 105x80mm Top Plate with 80mm x 60mm Bolt Hole Centres. The overall height is 95mm.The Nylon castor wheel is a hard tread made from quality nylon. It will not damage or mark concrete floors and is not susceptible to picking up floor debris and swarf. Nylon is a popular wheel choice because it is light weight and has a high load capacity relative to other wheel materials of the same size. It is not affected by water and is insensitive to many chemicals apart from acids. - In Stock
100mm Shock Absorbing Swivel & Wheel Brake Castor With Brake, 100kg Capacity | Polyurethane Tyre Wheel (GDSB100BSFLUD75)
£98.14... Read More-variant-east-asian: normal; font-size: 14px;">100mm Shock Absorbing Swivel Castor with a swivel and wheel brake (also known as a total stop brake). This bracket houses a Polyurethane tyre wheel with an Aluminium Centre and precision ball bearings, The polyurethane tyre has a shore hardness of A90 and the Load Capacity of the castor is 100kg.
The Overall height without a load is 171mm and this reduces incrementally by up to 20mm as load increases (see image 2 - GDS100 Curve). It is fully compressed with a load of 75kg.
This is the only shock absorbing castor available with a total stop brake. The patented braking system over comes the issue of locking a swivel head that can move up and down providing customers with a castor that when braked, will stop any movement in the swivel head.

125mm AGV Swivel Castor, Twin Wheel, 440kg Capacity | Polyurethane Wheel, Ball bearing (GASD125ASFHUD)
£598.16This Twin wheel ... Read MoreAutomated Guided Vehicle (AGV) Castor with 125m diameter wheels has a shock absorbing function and a bracket made from strong Forged steel that is zinc plated. 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 145mm x 145mm and has 4 bolt holes that are spaced 120mm x 120mm, each with a 11mm 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

This ensures that this castor's wheels keep contact with the floor allowing smooth AGV movement and protection of the loaded cargo when changing directions (See illustration below)The wheels are more widely separated from each other than most Twin Wheel Castors. When changing direction, the two wheels spin in opposite directions to each other which reduces the castor offset.

The cast iron wheel centre is tyred in Flexello Superthane Red Polyurethane and fitted with a Roller Bearing. Load Capacity = 725kg.Jacking Castors help with the movement and quick and accurate vertical adjustments of working platforms, machines and other heavy duty applications. This enables users to raise and lower equipment for its safe movement.It is important to note that the minimum Jacking Castor load capacity is obtained by calculating the total weight to be carried (unladen unit weight + maximum load) and dividing that by 2. This is because the operation of Jacking Castors means that each castor can be subjected to half the total weight.Most applications require 4 Jacking Castors and in this situation, the recommended total maximum load that can be carried by 4 Jacking Castors is 1,450kg. - In Stock
