One of the most important things to consider when selecting caster wheels is the weight of the load. The heavier the load, the larger the wheel. For loads over 400 pounds, ball bearings are recommended. Some casters feature polyurethane wheels to protect flooring. Likewise, extreme temperatures can affect the performance of casters. This is why most industrial casters feature special lubrication to protect them from extreme conditions.
Another benefit of caster wheels is their durability. They do not require treads or air to move, which makes them highly durable. You can move them over obstacles and across hard surfaces with little or no effort. In addition to improving the overall speed and efficiency of moving objects, these wheels also make moving heavy objects a lot easier. They are also easier to maintain and clean, reducing the risk of accidents. This makes them an excellent choice for a wide variety of applications, including industrial machines and carts.
One thing to keep in mind when purchasing caster wheels is the weight. A heavier load will put more strain on casters and make them difficult to maneuver. Also, caster wheels with large diameters will be able to roll over rough surfaces without any difficulty. To prevent damage to the floor, choose wheels with polyurethane or soft rubber. These materials provide flex and absorption, making them more durable.
Size is another important consideration when choosing casters. In a nutshell, the size of a caster depends on several factors. For example, if the caster wheel is meant to move expensive items, it should be small so that you have full control of the cargo. On the other hand, large casters are used in the aerospace industry, as they are designed to handle heavier loads. Larger wheels are easier to roll and protect floors.
Another factor to consider is the type of flooring the cart will be used on. Smooth floors like wood require protection from wear and tear, so softer casters should be used. In contrast, carpet requires special considerations for ease of rolling and durability. Thick carpet requires larger caster wheels to avoid snagging the flooring. Finally, the weight of the cart also should be taken into consideration when purchasing casters.
Besides weight, caster wheels should be lubricated and feature fastenings for mounting. Casters should have a tread, which is a rubber fitting that prevents dirt and other debris from entering. The tread should be free from damage or flaws, as it can lead to unnecessary wear and tear on the casters. A damaged tread can also damage the hardware and lubricant.
Swivel radius: This factor determines how much space is needed for the wheel to swivel 360 degrees. To measure the swivel radius, measure the horizontal distance between the center of the kingpin and the floor. Usually, caster wheels have a radius of about four to six inches, but you can make a more accurate measurement with a ruler. This measurement will ensure the casters last for years, reducing maintenance costs.
Pneumatic and flat-free casters have different characteristics and benefits. Pneumatic caster wheels require more initial push force, have a larger footprint, and are subject to punctures. Forged wheels are better than solid wheels, but need to have more cushioning. In addition, they tend to last longer and can withstand high temperatures. However, both types are prone to punctures. If you’re going to use them regularly, make sure to read the manufacturer’s documentation to be sure you have all the information you need.
Weight capacity and wheel size are also important factors. Casters-wheels should be able to handle the weight of the load you intend to move. The weight capacity of a caster wheel is determined by its diameter, width, and material. You’ll need more weight capacity than its calculated capacity in order to prevent damage. For example, you can choose four 250-pound wheels if you’re planning to transport 1,000 pounds of equipment. For loads above 400 pounds, ball bearings are recommended.
