Caster wheels are used for moving materials, equipment, and furnishings. They help to move items easily, reduce friction, and increase efficiency. There are many different types of casters and applications.
What is the difference between a wheel and a caster?
When selecting a small caster wheels, consider the type of surface on which it will be operated. This is important because some wheels are suited for certain surfaces. Also, the wheel material can influence its performance and durability.
Caster wheels can be made of aluminum, steel, or polyurethane. Polyurethane is a solid material that is strong and very durable. It is also very easy to roll.
Forged steel wheels can be equipped with Teflon, roller, or plain bearings. These are ideal for use on concrete, oily, and mildly corrosive environments.
Glass filled nylon caster wheels are able to operate in oily, hot, and greasy environments. They are resistant to abrasion and are tough and non-marking. The wheel can operate in temperatures as low as 45deg F.
Aerospace caster wheels are typically pneumatic. However, they can also be made of solid rubber.
The wheel material also affects the noise level. Most chemicals and oils are not able to damage hard rubber wheels. Hard rubber wheels are generally made of one piece, making it simple to start and operate.
Hard rubber casters are available in soft and hard varieties. Soft rubber has a lower load capacity than hard rubber. However, they offer good rolling ability and are less likely to flatten while under load.
