Each caster and wheel carries a maximum recommended load
capacity. These load ratings are based on manual operation with
intermittent service not exceeding two miles per hour. Uneven
load distribution or careless in-service loading of the castered
unit may necessitate decreasing these ratings slightly even
though a safety factor is included. Most load ratings are in
accordance with Caster & Floor Truck Manufacturer's
Generally, larger diameter wheels roll easier and absorb
shock and abuse to a larger degree than do smaller diameter
wheels. Wider treads operate with less resistance on soft
surfaces and spreads the load for better floor protection.
Soft tread wheels will protect floors and offer the most
quiet operation. All-hard wheels have longer life in industrial
locations where metal scraps, steel grating, broken cement and
similar conditions may be found.
Casters are available in four basic swivel type construction:
Top-bearing; Uni-level; Duo-level; and Double Ball Race. Each is
designed for maximum efficiency and economy in specific
A wide variety of plate and post mountings are available to
meet specific installation requirements. Post sockets are also
available for installation to the castered unit.
Soft tread and all-hard rubber wheels are the most economical
for normal applications. Other compounds are also available for
specific applications such as conductive rubber, neoprene and a
variety of mold-on wheels.
Side brakes, contact brakes, floor locks, thread guards,
grease fittings on raceways, and shimmy dampeners are offered on
some models. Roller bearings and grease axles are also available.
Hard thread wheels have considerably greater load rating than
comparable soft tread wheels primarily because they do not tend
to flatten as easily. As a result, hard tread wheels roll easier,
swivel with less drag under heavy loads and take less compression
* Heavy loads
* Seldom moved jobs, either light or heavy
* For use on carpeting
* Outdoors or where grease and oil may be a problem
* When noise is not a significant factor
Soft tread wheels generally have lighter load ratings than
hard tread wheels. They produce quieter operation of the castered
unit by absorbing the floor surface imperfections which are
normally transmitted through the unit. Soft treads also provide
better swiveling action under light loads.
*Hard, uneven operating surfaces
*Frequent movement of light loads
The most common and inexpensive type of bearing is the
"plain" bearing. A plain bearing may be sintered metal
that is impregnated with oil for lifetime lubrication. Plain
bearings are the most popular for light load applications,
Ball bearing wheels provide the greatest rolling ease but
generally have the shortest life span. Because of their low
friction and the ease with which they roll, ball bearings perform
best under light - medium load applications.
Roller bearing wheels are best suited to heavy load
applications. They provide optimum rolling ease and the longest
life span at both high and low speeds
