What is a dual wheel caster?

Dual wheel casters have a higher weight capacity per caster, allowing for increased productivity, while enhancing stability. They also spread the load across the two wheels, reducing the load-per-square-inch and reducing pressure on the flooring or ground surface.

What is a fixed caster?

Fixed casters consist of a fixed, non-swivelling housing to which one or more wheels are mounted. They are generally mounted in combination with swivel casters to provide directional stability to machines and equipment. In special cases, only fixed casters are used.

How many types of caster wheels are there?

When considering maneuverability, there are two basic kinds of caster: rigid casters and swivel casters. A rigid caster, also known as a fixed caster, is only able to roll forward and backward. A swivel caster has a raceway that allows the wheel to turn.

What are twin wheels?

Twin wheel casters are typically made of nylon and thermoplastics and have two wheels that are riveted or friction-fitted to an axle on the outside of a central body. Twin wheels can be hooded or non-hooded in design; both still feature a central body that the wheels are assembled to.

What is the difference between a fixed and swivel castor?

Here’s what you need to know. Rigid Casters: One Direction Rigid or “fixed” casters allow you to move your materials or equipment back and forth in a straight line. They can’t turn corners, but they’re stronger than swivel casters and can support heavier loads.

Why are castor wheels called castor wheels?

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!

Why are casters offset?

When moving straight ahead, the offset ensures stable running characteristics. It also influences the load-bearing capacity of the castors and the amount of wear on the back bearing.

What do I need to know about my twin wheel caster?

The first thing you’ll want to write down is the type of mounting used by your twin wheel caster. See the below images to help you correctly identify and how to measure your twin wheel’s top plate or stem using your ruler.

What are the most durable caster wheels?

The most durable plastic wheel, the nylon wheels on these casters are impact and wear resistant. They work well on smooth surfaces. The wheels dissipate static to protect sensitive electronic equipment from electrostatic discharge. Also known as twin-wheel casters, these lightweight and economical casters are often used on furniture and displays.

How are casters measured?

Wheel Diameter is the measurement of the distance across the central-most point of the wheel. This is one of the most commonly used measurements for casters. Tread Width is the measurement of how wide the caster tread is. You can find this measurement looking at the rolling surface of the wheel. This is another commonly used caster measurement.
