8 x 2" Polyurethane Castor Wheels - Swivel And 4 With Brake (2024)

FAQs

What is the difference between a caster wheel and a castor wheel? ›

Castor is a British term for caster wheel, whereas caster is an American term for caster wheel. A caster or castor is a pivoting roller attached to the bottom of furniture or a portable machine for easy movement.

Polyurethane wheels are more durable and have a longer lifespan than rubber wheels. They also provide better shock absorption and are quieter, making them ideal for carpeted floors. Polyurethane wheels are also resistant to chemicals, oils, and grease, which can cause damage to rubber wheels.

Calculating Load Capacity. The first step in figuring out how much each caster must support is to divide the total load by the number of casters. For a 4-wheel material-handling cart that must support 1,000 lbs., for example, dividing 1,000 by 4 gives a minimum load capacity of 250 lbs. per caster.

Caster settings are not a primary, direct factor in tire wear. However, excessive positive caster in association with other alignment maladjustments can exacerbate a tire wear issue. For example, a tire wear pattern called feathering can result from a combination of too much caster with incorrect toe settings.

Typically, castors are favoured in dynamic environments where mobility and flexibility are key for the user to roll from one area to another without standing. In contrast, gliders, also known as bell glides, replace the wheels with stationary feet.

Potential Drawbacks of Polyurethane Caster Wheels

They possess lower heat resistance, making them susceptible to deformation or disintegration in extreme thermal environments. In high-speed operations, the rolling resistance of polyurethane wheels becomes higher and prompts decreased efficiency and increased wear.

Polyurethane wheels are a great product when riding due to its resilience to wear and tear. The chemical compounds produced by the additives make a product that will last forever.

Soft rubber and polyurethane are the wheel materials where flat spotting most often occurs. There is a chance that the flat spot can disappear as the wheel begins to roll and take its true form again back to its original state but this does not always happen.

That's why shopping carts, for example, have fixed casters in back and swivel casters in front. The fixed casters at the back act as a fulcrum, making it easier to turn corners and also to move the cart in a straight line. California Caster carries rigid and swivel casters for any application.

Do bigger casters roll better? ›

First, the larger the wheel, the easier it is to roll over rough or uneven surfaces. Second, bigger wheels can carry more weight without breaking or becoming damaged. Finally, larger caster wheels are less likely to get caught on small objects or debris, making them ideal for use in outdoor or industrial settings.

A Sloppy Swivel Section – If the swivel section is too loose, it can cause the caster to flutter uncontrollably. A loose swivel section, no matter the diameter of the raceway, will create resonance leading to flutter.

Determining the Load Capacity for Your Needs

For instance, if you want to move a 2000 lb load on a 100 lb cart with four casters, the calculation would be as follows: (2000 lbs + 100 lbs) * 1.33 / 4 casters = 699 lbs per caster.

In addition, you can perform a simple calculation using caster wheel weight capacity. First, calculate the total cargo weight. Then, divide this number by your proposed number of casters. If the final number is smaller than the load capacity of each caster, you are on the right track.

A castor wheel is a relatively small undriven wheel, meaning that it is free-rolling (as opposed to powered). They are designed to be attached to the bottom of a larger object, to enable easy movement across a floor or other hard surface. Castor wheels are often referred to simply by the standalone term 'castors'.

As the center hub of the wheel revolves around the center of the swivel section it is said to “cast” in that small circle. Thus, caster! This essential swiveling feature of casters makes it so much easier to move heavy loads and turn tight corners in a warehouse.
