Are all caster wheels the same size?

Whilst they are typically 2-2.5 inches in size as standard, it is the style of the castor stem (the part which attaches the wheel to the chair leg) which determines whether the wheels will fit in other office chairs. That said, most office chair castors will use a grip ring style stem.

Are casters standard sizes?

Moving on to the Light Duty/Institutional casters, things become much simpler from here. The most common top plate size is 2-3/8″ x 3-5/8″ with a bolt hole pattern of 1-3/4″ x 2-7/8″ slotted to 3″. Although there really is no “standard” in the industry, this would be what I consider typical size in this series.

Are rubber or polyurethane casters better?

This extra-hard polyurethane is ideal for heavy loads, with non-marking and wear-resistant properties. Corrosion Resistance – Finally, urethane wheels are far superior to rubber casters because they won’t corrode or break down as readily when exposed to heat, water, or even certain chemicals over time.

How much weight can caster wheels take?

Casters come in three weight ranges. Light duty casters are for loads of up to 500 lbs. Medium duty casters are for weights of between 501 and 2,000 lbs. And heavy duty casters are for weights of more than 2,000 lbs.

How much weight can 4 wheels hold?

We recommend adding a 33% addition to the total weight of the load for safety. So, for a 4-wheeled cart that weights 3,000 lbs., the safety factor would equal 3,990 lbs. Dividing this weight by 4 gives a caster with a rating of 1,000 lbs per caster, which is recommended.

Are rubber wheels better than plastic wheels?

Plastic blow molded wheels are hollow and can fill with water in some conditions. If that water freezes, it can affect the ability to roll the cart or worse, crack the wheel itself. Rubber wheels are solid throughout and withstand extreme weather and freeze/thaw cycles.

Are bigger casters easier to move?

In general, wheels with greater diameter and width have lower starting resistance and rolling resistance—it’s easier to get them moving and keep them moving.
