Aerol Casters are made of high-quality materials designed for a variety of applications. While durability and dependability are built in every caster we manufacture, let’s discuss what goes into building an Aerol caster.
The adaptability of aluminum to permanent mold casting provides the ultimate in modern material handling. While we do offer a variety of steel casters, the majority of Aerol casters are constructed of 356T6 aluminum alloy that is heat treated to improve strength. Aluminum provides high corrosion resistance, high tensile strength, and uniform sectional properties. The added T6 treatment provides excellent hardness.
These casters are designed to perform in challenging environments, like the many different situations encountered by the military. In fact, Aerol brings an esteemed reputation dating back 76 years as a contractor for the defense and aviation industries during WWII.
Designed for heavier demands, Aerol also features shock-absorbing casters for maximum shock absorption under all conditions — even when the truck or dolly is empty or nearly empty.
Our aluminum corrosion-resistant casters are lightweight but not light on strength. These casters can handle a max load of 10,000lbs per caster and withstand the elements. This makes them a perfect choice for Navy and Coast Guard applications where corrosion is a problem for steel and iron. Another advantage of aluminum casters is that their weight can be half that of iron or steel.
Another question we get asked often is “How often do you have to lubricate your bearings? The answer? Never. That’s because our casters are maintenance free.
High-performance lubricants are used in our maintenance-free casters, providing a high melting point and a low cold test. The upper and lower seals on Aerol bearings feature a neoprene “O” ring. Aerol casters also feature a positive pressure seal designed to withstand constant exposure to a wide variety of temperatures, water, steam, pressure, vacuum, detergents, abrasives, and many other conditions.
The bearings in our maintenance-free casters permit both radial and thrust loads capable of providing maximum performance and reliability. They are pumped with grease and sealed on each side of the ball raceway. This seal keeps the grease locked in and keeps dirt or liquid out for a durable and long-laster caster in the toughest environments.
Aerol casters are also spark proof. The lack of ferrous metals in the aluminum caster means it won’t cause sparks that could ignite under the right conditions. This is extremely important for applications that require explosion-proof equipment used in hazardous conditions.
