How to select the Proper Caster & Wheel
There is no simple formula or rule that can be followed in selecting the proper casters. Many individual factors must be
balanced to make the selection. The following are several of the more important considerations.

Caster Combinations for Mobile Equipment
In building, repairing, and refurbishing mobile equipment, various effective caster combinations may be used.
Several types of mountings are illustrated below.
Several types of mountings are illustrated below.
Three Swivel. For barrel dollies and small portable machines. Affords excellent maneuverability. Be sure to select casters designed to take the weight load on three casters rather than the usual four.
|
Tilt Mounting. A tilt mounting is the most economical, but should be limited to lighter loads. The tilt is best when the load wheels are 1/8" taller than the balance wheels. Not recommended for use on ramps.

||
Four Swivel. Where a side motion is frequently needed, the four swivel arrangement is excellent. If the casters are equipped with swivel locks, this mounting is also practical for long straight travel as well as use on ramps. A most versatile arrangement.
|
Two Rigid, Two Swivel. Most practical and inexpensive arrangement for straight and/or long distances. Can be used for heavy or medium loads, depending upon the weight capacity of the casters selected.

Diamond Mounting. Two rigid and two swivel casters, but the diamond shaped mounting greatly increases maneuverability. This mounting is not recommended for ramps.
|
Four Swivel, Two Rigid. This is a level mounting design for heavy loads and long trucks. The two rigid casters help to distribute and reduce the load on the swivel units and thereby maintain good maneuverability and easy steering.
