Pneumatic wheels are designed to mimic car tires. Essentially, they are rubber wheels fitted around a metal hub. Many are filled with air, and some may also be filled with soft foam. They come in a variety of different sizes and styles, and they are available for anything from light-duty to heavy-duty applications.
Many industries utilize pneumatic caster wheels to move fragile loads – meaning those that may become damaged with minimal jarring or bumping – over any kind of surface, including grassy areas, pavement, and concrete floors in industrial facilities. These wheels are known for their quiet operation and ability to improve working conditions in loud environments.
The complete line of single or dual-wheel pneumatic casters offers load carrying capacities from 320 pounds to 7,260 pounds. The swivel sections are constructed of C-1045 hot forged steel with double row ball bearing swivels for long service life. The 80 Series and larger casters have tapered thrust bearings in the swivel. The legs are continuously welded both inside and outside for added strength. Standard: Wheels 16” and larger are supplied with high-speed tapered bearings standard.
These casters offer the greatest possible protection to both loads and floors. The pneumatic tires cushion the load and roll over obstructions with ease. These casters provide longer wheel life, less maintenance and high shock absorbency. The long swivel offset aids in swiveling and tracking in towing applications. When the caster is subjected to towing, tapered bearings are recommended.
Excellent shock absorbing benefits make these casters ideal for uneven floors and indoor and outdoor rough terrain. They are ideal on aircraft ground support equipment, helicopter dollies, roof maintenance equipment, mobile construction shelters, and other equipment carrying electronics or other highly sensitive materials.
Caster Concepts has a wide variety of caster options. Many of these not only improve function – but also provide safety and add longevity to the product. When considering safety options, the most common consideration would be caster locks, caster brakes, toe guards, and reinforced legs. Options that extend the life of a caster are primarily options that seal the bearing of the caster to prevent contamination of the precision parts.
Other options include threaded zerks for when an application is difficult and high level of maintenance is required and rack brush wipers that keep debris from stopping movement or damaging a wheel. These options can be added at the time of manufacturing or after the caster is fully assembled.
