A caster or castors or casters wheel is a wheel-like device attached on the bottom of an object to enable it to move. They are often used to transfer large objects, such as heavy pieces of equipment or industrial tools.

Caster types

There are two basic caster types: rigid and swivel. Rigid casters are typically more robust and durable, and they tend to restrict movement in a single direction. They are generally preferred in environments with heavier loads that need to move in a straight line.

Swivel casters, on the other hand, are affixed so that they can change direction, in a 360 degree fashion. They are less robust than rigid casters, but they can still carry heavier loads.

Casters or Castors: Understanding the Differences and Choosing the Right Option for Your Business

The wheels on casters made for moving heavy items are typically made from cast iron, ductile steel, or phenolic. The materials of these wheels vary, depending on the environment in which they are used and the type of floor or surface on which they roll.

Inspect the treads and construction of a caster’s wheel on a regular basis to detect damage that could lead to premature failure. If you discover flaws, replace them before they become a larger problem.

Make sure to check the hardware fittings that hold the caster wheel in place on a regular basis. These include nuts, bolts and screws that prevent the caster wheel from moving or falling off completely.

A caster is a critical piece of equipment in many businesses, and it’s important to keep it in good condition so that you can use it for years to come. The best way to ensure a caster’s long-term integrity is to inspect it on a monthly basis and apply lubrication as needed.
