There are several different types of caster wheels on the market. The most common is a swivel caster like some 5 inch caster wheels, which has a rotating assembly that allows the wheel to pivot in any direction. This makes swivel casters ideal for moving objects from one location to another. They can also be ordered with a locking device for added safety. However, swivel casters are not the best option for every application. For example, a rigid caster may be your better option if you need your caster to roll in one direction only.
Ductile Iron
Cast-iron wheels are stronger than their semi-steel cousins. These wheels are also able to withstand high temperatures and sharp impacts. In addition, they come with lubrication fittings in the hub. They are also suitable for applications where water is present. However, they aren’t a good choice for applications that require frequent cleaning.
Cast-iron wheels are available in a variety of sizes and materials. These wheels are a good choice for rough surfaces and can easily handle scrap metal and glass particles. The 1-1/2″ and two-inch wheels come with 3/4″ roller bearings and are standard with a 1/2″ spanner. Because they are so durable, these wheels are ideal for heavy-duty applications.
Gray Iron
Gray iron caster wheels are constructed with premium Class 30 gray iron that provides maximum impact strength and load capacity. They feature heavy cross-section castings that resist abrasion. These wheels are also corrosion-resistant and can withstand extreme temperatures. In addition, these wheels feature precision tapered bearings that add to their durability.
Gray iron caster wheels are more affordable than forged steel caster wheels but are just as durable. These wheels can be used on concrete or wood blocks but are inadvisable on untreated floors because they tend to cause rapid deterioration. Their smooth treads are also not recommended for floor protection.
Gray iron caster wheels are a good choice for the frequent transportation of goods. They are suitable for 280-420 kg of weight. The 90-degree grooves in these wheels direct the load and ensure proper weight distribution per wheel. They are available in different designs and can be purchased online. These wheels are also available in several sizes, which makes it easy to choose the one that is right for your application.
Caster wheels need to be durable. You should choose a wheel that can withstand extreme temperatures and the type of floor. These wheels should be resistant to chemicals, oily floors, and grease. They should also be durable enough to resist shocks.
Forged Steel
Caster wheels are a great choice for heavy-duty applications. These wheels are designed to handle the heaviest loads without losing their balance. Often, heavy-duty casters are designed with heavy-duty forged steel construction. Casters can be light, medium, or heavy-duty, depending on their weight and environment.
Forged steel caster wheels are durable and can withstand various applications. They feature high-heat resistance, a nearly unbreakable construction, and the ability to absorb shock impacts during power-drawn service. However, forged steel wheels are not recommended for use on light loads. Temperature ranges of forged steel wheels can be as low as -45oF to +180oF, with optional metal washers extending the temperature range to 500oF. Forged steel wheels are finished with a green alkyd enamel finish to ensure durability. In addition, a zerk fitting in the hub is standard.
A forged steel wheel is made from high-carbon steel billets. They are then repeatedly hit by high-tonnage forging hammers to create a flat, precision-machined wheel. The result is a wheel with the highest load capacity of any caster in its class. As a result, they are ideal for heavy-duty industrial applications and can support up to 30% more weight than gray iron casters.
Inspecting caster wheels is a crucial step in keeping them in good condition. It is vital to inspect for deterioration every month. You can replace damaged caster wheels before they become a larger problem. If you maintain your casters properly, you will get a long life out of them and prevent the need for expensive replacements.
