Aluminum heavy-duty casters that fully support the Aerospace ground support industry.

When it comes to harsh environments, heavy weights, and unforgiving timetables, it’s tough to find more extreme conditions than the ground support equipment associated with airport and aircraft manufacturing facilities face daily.  And not just any caster wheel will do for many of their applications.

Aerol was the first to manufacture a permanent molded all-aluminum caster and wheel. This aluminum construction and sealed bearings offer a maintenance-free, heavy-duty caster. That fills a critical need for casters that can take all the abuse that’s dished out and roll with it.

Caster wheels that are lightweight in every area but performance.

Aerol is directly responsible for the evolution of ground service equipment, designing everything from simple caster-mounted dollies to elaborate running gear systems. Our aluminum casters include the yoke, swivel section, and wheel core.  The all-aluminum construction also means that the overall weight of the caster is reduced to about 1/3. The importance of equivalent steel and iron core wheels. But this reduced weight doesn’t mean reduced performance: you’re still assured of the same strength and capacity that you would find in a typical steel caster.

The universal acceptance of Aerol wheels and casters for high-performance environments supports the choice of aluminum as the base material in producing premium components. Having a caster wheel built entirely out of aluminum offers several benefits, including:

  • Corrosion resistance. Aluminum casters are ideal for outdoor use in wet and humid environments. Also, carts and equipment utilized in the aerospace industry face many conditions.
  • Stands up to water and many chemicals. Besides being highly resistant, aluminum is also designed to function flawlessly in various conditions and is non-sparking and non-magnetic. However, aluminum is strong and durable like other metals and an excellent thermal and electrical conductor.

Keeping aircraft, aviation, and aerospace on the move.

Aerol has earned an excellent reputation as a leader in providing superior casters used in Aviation Ground Support running gear and Aircraft Maintenance equipment. The military, major airlines, aircraft manufacturers, and ground support service providers choose us for casters that deliver trouble-free service.

Each wheel is on its separate axle with separate legs: it’s like having two separate casters on one top plate. This is highly beneficial because it helps to keep both wheels on the ground to help keep the cart or dolly level, even when the ground isn’t level or an obstruction is encountered. It also helps avoid excessive stress on just one caster wheel, reducing the risk of failure and potential injuries.

Running Gear Applications

For commercial running gear applications, Aerol offers three “thru-axle” running gear designed to handle most situations. These designs are:

Light Duty — 4,000 lbs. per axle
Medium Duty — 8,000 lbs. per axle
Heavy Duty — 12,000 lbs. per axle.


In addition to Commercial Running Gear, Aerol manufactures an extensive line of mobile equipment components and assemblies that meet the requirements of Military Specifications. These include the Banjo Mount, where the wheels and spring suspension are mounted on the side of the carriage with rotary movement, and the SAM Suspension Unit, which also mounts on the side of the carriage and features linear motion.
