TYPICAL USE IN THE INDUSTRY OF THE DIFFERENT COMPOUND WHEELS IS AS FOLLOWS:

  • Nylon wheels: These are the cheapest, but some of the toughest wheels in the range and can take quite a pounding. Typical use would be in the food industry as it does gather the minimum amount of debris, and easy to hose down after a day’s work, without damaging the actual wheel. Nylon wheels is also popular for use in cold environments like walk in fridges and blow freezers as they can operate in temperatures up to 20 degrees Celsius below freezing. Suitable to use in wet conditions. Available in various sizes.

  • Nylon Polyurethane wheels: Similar to the nylon wheels, these are also preferred wheels for the foods industry and cold conditions like walk in fridges etc. Suitable to operate in wet conditions. Available in various sizes.
  • Rubber wheels: The most common and popular wheels, and is pretty much an all-rounder as explained above. Rubber wheels can be used in most environments and conditions except wet conditions, as the rubber absorbs the water and will thus shorten the lifetime of the wheel.
  • Cast iron polyurethane wheels: Cast iron center wheel with ball bearing with a polyurethane bonding. The polyurethane is chemically bonded to the cast iron center to insure robustness. These wheels are widely used in the engineering, manufacturing industries. Typical uses for moving heavy duty applications such as gantry’s, machine moving and various other heavy equipment. Available in various sizes.

  • The most important factor to take into account when choosing a castor is to determine the weight of the application or goods that needs to be moved.
  • It is important to work with a safety factor to spread the load evenly, for example if your application requires 4 castors, you would spread the total weight over the carrying capacity of 3 castors to allow for the safety factor. Example: if the total weight is 200kg, three of the castors need to be able to support the full weight of 200kg each carrying for example 70kg equalling 210kg. Surfaces vary and might not always be even, thus to prevent failure of wheels when pushing a trolley (or other application) with 4 castors over an uneven surface at some point one castor might be “airborn” for a brief moment and the other 3 castors now need to support all the weight.

  • When the weight has been determined also note there are different wheel diameter castors available each carrying different loads (for example: 32mm, 50mm, 75mm, 100mm up to 400mm) which could also be an important factor as certain applications and use could be height restricted. Also take into account the total height (top to bottom height) of the complete castor.
  • Choosing the type of wheel for your castor (ranging from nylon wheels, nylon wheels with polyurethane bonding, rubber wheels, cast iron wheels, cast iron wheels with polyurethane bonding) is also a very important factor. Rubber wheels are the most common wheels used in castor brackets as the rubber wheels we sell are non marking, absorbing some of the shock when moving goods over an uneven surface like paving, asphalt etc. and reducing noise and vibration when carting goods around. In the manufacturing industry some companies have expensive epoxy coated floors and it is important to use the correct wheel to prevent damage to the flooring.
