Also known as: Nylon Roller, Nylon Wheel Castor, PVC Castors, Polymer Wheel, Cooler Wheel, Trolley Castor Wheel, PU Castor, Furniture Wheel
A Wheel Castor is an undriven, single, double, or compound wheel that is designed to be attached to the bottom of a larger object to enable that object to be moved. They are available in various sizes, and are commonly made of rubber, plastic, nylon, aluminum, or stainless steel.
HOW TO CHOOSE THE PROPER CASTOR FOR YOUR NEEDS
AN UNLIMITED COMBINATION OF VARIABLES DETERMINE THE COMBINATION OF COMPONENTS THAT A CASTER NEEDS FOR A GIVEN TASK. THE FOLLOWING DESCRIBE VARIABLES TO CONSIDER WHEN CHOOSING THE CASTER THAT IS RIGHT FOR YOUR USE.
- Load Weight: The higher the the load weight, the larger and more dense the wheel required. Gross weight of a truck/dolly should be divided by the number of casters/wheels on which the weight is distributed.
- Floor Conditions: Floor conditions affect caster and wheel performance. To view which wheels perform best on which flooring type, explore our wheel type page.
- Unusual Conditions: Each wheel has its strengths and weaknesses in unusual conditions. To view which wheels perform best in which condition, explore our wheel type page.
- Extreme Climates: Extreme heat or cold is a problem for most casters and wheels. To view a recommended operating temperature range for various caster wheels, explore our wheel type page.
- Rolling Ease: The larger the wheel diameter, and the harder the wheel material, the easier the wheel will roll. Roller bearings carry heavier loads. Ball bearings roll easier but carry lesser loads. Rolling ease is also affected by environmental and application conditions.

Prepare the Surface and Structure – It is important that the structure in which the Castors are to be mounted are sufficiently rigid to support the load. For example, if you are mounting the Castors to a previously non-mobile item (for example a table) it should be considered that the Castors will concentrate the load over the surface area of the Top Plates, as opposed to the full surface area of the structure (i.e. wooden base). It may therefore be necessary to “build-up” the corners with extra wood, to increase the strength.
For Large Equipment, or relatively week wood, castors in the center or outside edges should be considered to provide additional support to stop the wooden structure from flexing.
Marking Out – Place the Top Plate onto the wooden board, and position into the desired place (making sure not to position to close to the edge of the wood). Now, using a Pencil, mark each of the 4 hole positions onto the wood.
Repeat above step for each Castor Wheel Position
IMPORTANT: The alignment of the Castors is extremely important. Castors should generally be positioned symmetrically +/-1mm, unless other positioning has been designed, however alignment is extremely important to ensure stress is not applied to the Castor Fork, which during a “turn” could cause the Castor Fork to buckle.
Pilot Holes – Once the “Bolt Holes” have been market out and the alignment and positioning has been checked, the next stage is the drill pilot holes. Using a drill piece which is approx.. 50% the diameter of the bolt, a pilot hole should be drilled for each bolt hole position.
Install the Castors – The Castors can now be placed into position and screwed into the equipment. The strength of the screw/bolt is important, and we advise using grade 8.8 for optimum performance.
Check the Maneuverability – Now that the Castors have been installed, you should test the equipment to ensure that the wheels all function as required. Particular attention should be paid to any wheel that is not making full contact with the flooring surface, in which case packing shims should be used to correct the height.
