Flanged Wheels for Controlled Workflow

The flanged caster wheel is perfect for any situation requiring the use of a track. The flange (whether dual or single) keeps the wheel from jumping off the track during use.

Flanged wheels set themselves apart from other wheels by having a lip around one or both outside edges of the wheel. Most people will be familiar with flanged wheels as those on trains or old mining carts, however they are popular for many industrial and factory setting applications.

The use of a track with a flanged wheel can provide several advantages over a standard wheel rolling on the floor. The floor itself will see less wheel wear, and the caster unit and wheel will have less chance to pick up debris on the floor. Flanged wheels also provide tracked workflow to maintain controlled mobility as well as providing the ability easily raise or lower the work.

Another distinct advantage is the ability of the flanged caster to bring the work overhead. A good example of this is on cranes and hoists that use flanged wheels to roll on an I-beam.

Service Caster Engineers Mining Wheels

Mining Wheel

Service Caster steps outside the box, and goes underground to produce a wheel for extreme conditions.

The mining industry was in need of a wheel to carry its 140,000 pound capacity mining tuggers. Tuggers are used to pull mining equipment into and out of mines. These slow moving vehicles, about one mile-per-hour, had to have a specially designed and built wheel to handle the workload and rough surface of the mine passages. The engineers at Service Caster put the catalog aside and got to work.

The result is a massive wheel weighing over 1,300 pounds. Standing 36 inches tall and with a width of 22 inches, these cast iron core, super extra heavy duty polyurethane wheels are made to withstand the rigors of the mining environment. The substantial width of each wheel offers more surface contact, in effect spreading the pounds per square inch over a larger area. The heavy duty polyurethane tread will allow the tuggers to roll over debris in a smoother fashion than a solid iron or steel would allow.

Caster and Wheel Bearings

A confusing term at times can be bearings in regards to their use in casters. Bearings are used in casters for both wheels and swivel heads, and here we will discuss both.

Wheel Bearings

Wheel bearings sit between the wheel and the axle, and provide a way for the wheel to easily spin on the axle. These bearings come in a number of different types, each with its own advantages.

Delrin bearings are inexpensive, and need no maintenance. They are a simple bushing made of Delrin, a plastic material. Delrin bearings work well in wet applications since they have no moving or metal parts that could corrode.

Roller bearings are best suited to low speed, manual operation with intermittent use. The roller bearing consists of a series of rollers arranged to sit on an axle and easily roll around it. Roller bearings can be solid or split caged. Split cage roller bearings do not handle side thrust as well as their solid counterpart, which is inserted into the wheel with a press. Roller bearings require regular maintenance.

Precision Bearings are a high quality ball bearing. These are excellent for applications that require high speed, quiet, and/or continuous operation. Precision bearings do not require regular maintenance to function properly. Semi-Precision bearings offer a less expensive, low speed and light duty option for those that still want quiet, maintenance free operation.

Tapered bearings are used on the heaviest duty casters. These bearings can handle high speeds and power driven application. Tapered bearings also handle side thrust well, and excel at continuous operation. They do require regular maintenance for good performance.

Swivel Head Bearings for Casters

Swivel Head bearings are typically ball bearings inside of a raceway. The swivel head assembly and its bearings allow for the wheel to easily turn and add steerability to applications. This raceway can be sealed or exposed. A sealed raceway protects the bearing assembly from dirt and other debris that is harmful to the bearing. The raceway can also be precision made and hardened to increase the longevity and performance of the swivel head.

Chair Casters for Carpet

We’ve already covered the types of casters to use for a hardwood floor, but not for another common floor medium: Carpeting. Carpet is very common, and casters can be used on anything from low ply to shag carpets, but the types of casters used will vary.

For a  low ply carpet, any hard wheeled caster will do the trick. Nylon, hard rubber, or other hard material will work well for the wheel. These materials will grip the carpet less than softer materials, making it easier to turn and roll. A rubbery material will grip the carpet, and feel like its sticking when they are moved.

For a shag or thick carpet, not only should a hard wheel material be used, but also the largest diameter caster wheel possible. Many times a large wheel is not desired, but the largest one possible should be used in this cast to prevent the caster from binding up in the carpet.

Many chair and furniture casters can meet these demands, so be sure to discuss your carpet type and options with a caster and wheel representative.
