Over the years, we’ve had a few people contact us in regards to our stainless steel casters. “Hey!” They say, “You’ve sent me the wrong casters. These are supposed to be stainless steel, but they’re magnetic.” We understand the concern, but have no fear… magnetism and stainless steel are not mutually exclusive. For example, stainless steel kitchen knives are often magnetic.

There are various types of stainless steel with a range of magnetic properties based on the atomic structure of the steel. Without getting too complicated, chromium content is what gives the steel its stainless properties. Sometimes, other materials are added to give specific attributes to the steel such as malleability or hardness. One such added material is nickel, which when combined with the steel creates the non-magnetism.

Our most commonly sold stainless steel casters are made with ferritic stainless steel, and they are magnetic. Some applications, such as MRI machines or special lab equipment, must have non-magnetic steel. If this is the case for your application, please give us a call at 1-800-215-8220 to discuss more options.

One question we get a lot here at SCC is, “Why choose a twin wheel caster instead of a single wheel caster?”

A twin wheel caster offers several distinct advantages over its single wheeled counterpart. Perhaps the most obvious advantage is weight handling capacity. If we take two casters with the same wheel diameter and material, but one is twin wheeled, it will handle more weight. Another way to look at this advantage is that we can use a smaller twin wheel caster to reach the same weight bearing capacity as a larger single wheel. This can be important if you need to maintain a lower load height within a specific weight capacity range.

Another great feature of twin wheel casters is their ability to turn easily. Where a single wheel caster must pivot on itself, a twin wheel caster’s wheels can rotate independently of each other, making turning or reversing direction much easier.

For more information on using twin wheel casters, give our customer service team a call at 800-215-8220 and we’ll be happy to help you out.

Most casters and wheels for industry and commercial applications contain some ability for exposure to temperatures above the norm. Typically, temperatures to 180 degrees Fahrenheit are possible. For those environments where higher temperatures are expected, such as a bakery oven or autoclave, caster wheel composition must be considered.

Recommended exposures to high temperature and length of operation vary. Also, consideration to the type of heat is necessary. These factors, along with floor surface, determine the possible lifetime of the caster wheel.

For locations with a dry heat, high temperature Phenolic wheels perform optimally. A safe range for estimating usage would be temperatures up to 475° F for 30 minutes of continuous operation.

When moist heat is expected, a glass-filled nylon wheel for high temperatures is the favored option. Conservatively, 475° F for 30 minutes continuous use provides the best scenario for a prolonged wheel lifetime. It should be noted that glass-filled nylon wheels are not for use in dry heat.

For issues of high heat, high temperature Phenolic and glass-filled nylon wheels are a solution for most environs. As noted, usage is permitted beyond the given parameters, but life expectancy of the caster wheels might be greatly reduced.

It might seem to be a simple task, choosing the appropriate wheel for a caster to be used in an industrial setting. In reality, though, the choice has many factors that should be considered for a lasting positive experience. Environment, workload, and capacity are just a few of the many considerations involved.

Industrial caster wheels need to be fitted not only to the device, but to the surroundings. Will the caster be exposed to weather, or extreme temperatures, such as an oven? Are there chemicals, oils, or other liquids that could be potentially harmful to certain wheel substances?  Is the surface with which the wheel will be in contact with smooth, rough, cracked, or have debris?

Of course, a caster wheel that can handle expected workloads and handling is a necessity. Is there chance of rough handling, or stress in a manner other than straight rolling? Perhaps the wheels are going to be static for long periods of time and only receive occasional use.  Not to be ignored is the power behind the wheeled device. Is that power to be supplied manually or by powered equipment?

Many times, the choice for wheels is made by weight capacity alone. However, consideration must be given to ergonomics. Will the wheel  begin to roll easily when engaged by a worker? Is the caster wheel going to give the least resistance when turning?

When choosing a caster wheel for industry, gather as many details as possible.  This data will be of great assistance when ordering casters. Service Caster sales reps are knowledgeable in all facets of wheel behavior, and will recommend the proper wheel for industrial usage.  Ready to order? Call us at 800-215-8220.

Pneumatic wheels have two major benefits over many other caster wheels. In addition, they come in a variety of sizes, styles, and tread patterns. Read on to find out if a pneumatic wheeled caster would be useful for your application!

The first major benefit of pneumatic caster wheels is that they offer a very cushioned ride. This is useful for applications that need protection from excess vibration, or travel over rough surfaces such as rocks, concrete, dirt, or grass.

The second major benefit is that pneumatic wheeled casters provide an extremely quiet ride even on uneven and rough surfaces.  This is helpful in any environment where noise is an issue.

A variety of options are available for pneumatic wheels. Choose selections for tube and tubeless depending on application. Multiple bearing types as well as bearing sizes allow for pneumatic wheels to be used on many caster frames. Tread styles also vary greatly, and include smooth, ribbed, diamond, sawtooth, and knobby tread patterns.
