Pneumatic wheels are replacement wheels that are extremely suitable for uneven such as Agricultural, Institutional; Industrial floors that usually demand rough and tough usage. Some of their features include the shock absorbing characteristics, their quiet operation, and ease of rolling that make them ideal for rough surface. Pneumatic Wheels are suitable for manual operation for both indoor and outdoor environments.
It is important to consider various factors while trying to identify proper castors and Pneumatic wheel because at the end each application is unique in its usage, function and output. IT is advised that a buyer should consider buying the castor or Pneumatic wheel that is suits their needs and application.
Criteria to consider before Selecting Castors and Pneumatic wheels include load weight, floor conditions, unusual conditions, temperature, swivel radius, Rollability and technical assistance.
The more heavy load is, larger the wheel diameter required for the castor and the Pneumatic wheel. The load weight also influences the rollability. It is advised that for loads over 250 pounds bearings be incorporated. When the momentary load imposed upon a castor or wheel when the load is dropped on equipment, strike obstruction or vibrates it should be able to absorb the shock and impact.
Castors and the Pneumatic wheels you opt for must be large enough to suit your peculiar floor conditions. It should be able to deal with cracks in the floor, moldings, or any other unforeseen obstacles.
The larger the wheel, the easier it is to roll. Make a note that a hard, narrow crowned tread rolls more easily than a flat soft tread on a smooth floor, but the wheel may be hard on the floor. Soft treads protect floors and pass over floor obstructions more easily. Make sure you use the largest wheel diameter for best results. Likewise, the larger the swivel radius, the easier the castor will rotate.
Before buying Castors and Pneumatic wheels you should identify your needs and then look for the particular features to suit your requirements. If need be you should seek technical assistance. This will help you getting the right castors and wheels.

Castors come in many shapes and sizes. Choosing the right wheels for you depends on what type of things you will be transporting and on what type of terrain. It is important to take these things into account because choosing the wrong type of wheels may either destroy your flooring, or excessively rough terrain may destroy your wheels. The following outline of the basic parts of industrial castors may help you to better choose the right wheels for you.
Mountings for castors
The top parts of the wheels are called the mountings. These are the top plates which are used to fasten your wheels to your platform. These top plates come in two forms ? 4 bolt holes or a single bolt hole. Top plates with four bolt holes are the most common as they spread the weight more evenly over the swivel head. Single bolt hole mountings are usually used for lighter loads. They are usually used over four bold hole mountings if the casters are to be fastened to a threaded tube.
Wheels
The most important thing to keep in mind when using pneumatic wheels is that they are specially designed for manual propulsion of up to 4mph. If you will be using your wheels for towing, this may damage your wheels or greatly reduce their lifespan. Wheels are categorized into two classes ? hard tread and soft tread.
Hard tread wheels move more smoothly than soft tread wheels due to their minimal tractive resistance. However, when used indoors they can be noisy and wear out flooring much faster than soft treads. Hard tread wheels come in four types ?
* Cast iron & steel ? good shock resistance and long lifetime
* Nylon ? high load capacity, light, clean, and minimal floor damage
* Polypropylene ? good load capacity, but not as damage resistant as nylon
* Phenolic ? abrasion and fracture resistant but liable to wear and chipping
Soft tread wheels are resilient, and less noisy and liable to damage your flooring than hard tread wheels, but they have a much higher tractive resistance.
* Solid rubber ? basic model, good temperature resistance
* Elastic rubber ? high load capacity and wear resistance
* Polyurethane ? high load capacity with abrasion, tear and chemical resistance
* Pneumatic ? good shock absorption, works well on rough, uneven surface
* High temperature ? rubber tires suitable for use in high temperatures
Bearings
There are several types of bearings used for industrial castors, and which ones you use will depend on the application, working environment, and loading levels.
* Plain bearings ? usually used with light load, intermittent applications, but vulnerable to axle wear and squeaking in wet or dusty conditions
* Roller bearings ? robust and ideal for regular use with light to medium loads
* Ball journal ? precision construction bearings for moderate to high radial forces
* Taper roller bearings ? used with larger dimension wheels for heavy loads
* Sintered bronze ? used for high temperature applications to minimise friction
* Teflon sleeve ? used to reduce friction and generally utilized for lighter loads than sintered bronze
Using this information to choose the best combination of mountings, wheels, and bearings will significantly increase your productivity and increase the lifespan of your casters. Taking the time to choose the best components will also reduce your costs in the long run.
