Frequently Asked Questions
Yes. The coordinated components insure optimum utilization of the BANJO and SAM units and permit a high degree of interchangeability for efficient logistics support.
- Individual, self-contained, side mounting precludes the necessity for a through the axle. This allows unlimited trailer design flexibility and fully cradles the pay-load. Ground clearance, regardless of sheel size, is at the discretion of the designer since the chassis can be raised or underslung.
- By simply varying the quantity or capacity of springs the same basic unit can handle a wide range of loads and EACH corner can be tailored for when an asymmetrically located center of gravity results in unequal loads on each wheel.
- Four standard bolts are all that is required to install the entire shock mount, wheel and brake assembly.
- With standard stub axles, wheel sizes can vary from a small 13 inch diameter to large over-the-road transport pneumatics.
- Brakes mounting flanges on both the BANJO and the SAM are compatible with AEROL parking brakes and AEROL hydraulic service brakes.
- There are no shock mount assemblies more compact than the AEROL units.
- The component parts of the AEROL SAM unit are completely inter- changeable between front and rear, left or right. Almost all of the component parts of the AEROL BANJO units are interchangeable one with another except for the back mounting plates between the non- steerable and steerable units.
- Years of testing, actual application and recordings by electronic accelerometers have proven many times over that the AEROL shock mounts can provide the best shock absorbing protection for your equipment.
The AEROL BANJO MOUNT for loads up to 1000 pounds per wheel, and the AEROL SAM SUSPENSION UNIT, for heavier loads up to 10,000 pounds per wheel. Both have gained wide acceptance in military and commercial applications.
These are the 8 most desirable feature in Running Gear:
- Adaptability to virtually all types of trailer configurations.
- A wide range of load capacities.
- Simplicity of installation and maintenance.
- A wide range of tire sizes.
- Parking and/or service brakes.
- Simplicity of design, using a minimum of component parts, with interchangeability to reduce spares requirements and thereby simplify logistic support.
- Effective shock absorption for the protection of equipment being handled.
After years of experience in the materials handling field, AEROL CO. approached the development of the RUNNING GEAR by first formulating a concept of the desirable features of RUNNING GEAR components for trailers and mobile ground equipment. Out of this in-depth study of the many facets of mobility for ground equipment, plus careful consideration of the military specifications, a list of the desirable features evolved.
As technology advances, AEROL, identifies with the transitional needs of the commercial and military industries. “Necessity has always been the Mother of invention” and AEROL’s policy has been to fill the need when it arises.
In layman’s language it is simply the mechanical apparatus used to “move” and “direct movement” of an otherwise immobile object safely and efficiently.
We assign each custom-designed caster a part number that begins with SP or SPD. This process identifies it as belonging to the customer who requested the design.
Why is this beneficial? A unique caster design is created for your company and no one else. This enables you to update or change your design at any time without changing the part number. You also have the option to view and approve a drawing before it goes to the manufacturing floor. If your need for a caster does not fit any of our standard casters, you’re not stuck! We can change things like overall height and width, mounting plate size, bolt pattern, swivel lead length, and more.
Take the weight of the load being carried and add the weight of the cart together. Take that total and divide it by three, which will give you the minimum rated load capacity each caster should have. This is also applicable for carts where a four-caster configuration is desired. (Division by three instead of four is due to the fact that three points make a plane, as well as that uneven floor surfaces frequently require three casters to carry the entire load.)
Caster Concepts has built a reputation for solving problems in the material handling industry. We are experts in application engineering and have over 150 years of cumulative experience devising solutions to customer challenges. In fact, a great deal of our business is the design and construction of custom and special casters.
Flutter or shimmy is a result of only three casters carrying the load. This is common and can be eliminated by extending the swivel offset, or lead, of the caster. The lead is the measurement from the centerline of the load raceway to the centerline of the axle.
Rough floors are compensated for in two ways. First, larger wheels will more easily travel over rough floors or outdoor surfaces. Second, resilient tire material such as polyurethane or mold-on rubber will flex, absorb shock and regain its normal shape.
Maximum towing speed is determined by the type of load being carried and the gross weight of the load. The potential problem with excessive towing speed is that heat may build up in the tire of the caster wheel, a condition that may cause premature tire failure. In most cases, we suggest a 10% reduction in capacity for every mile per hour over 3 mph.

Swivel lead is the distance from the vertical centerline of the swivel section to the vertical centerline of the wheel.
Swivel radius is the radius of the space measured from the vertical centerline of the swivel section that is required to allow a caster to swivel 360 degrees.
Our catalog load ratings take into account manual operation, speeds under 2.5mph, intermittent use, and temperatures under 110 degrees Fahrenheit. Where increased speed, power towing or frequent usage apply in your situation, please consult us for guidance on the proper caster selection.
Tapered bearings are used in applications where high loads are present and towing is the method of movement. Frequently towed trailers and carts are subjected to side thrust forces when the trailer is towed around a corner. The tapered bearing is used to compensate for the thrust load forces being exerted through the wheel. Tapered bearings are often referred to as “high-speed bearings” for this reason.
