Important NoticeSelecting the correct caster for your application is very important. If you do not select the correct caster, you or the users of your equipment could be injured. If you are not absolutely certain which caster is the correct one for your use, contact a safety or engineering consultant who knows your equipment and its intended use to assist you
IntroductionCasters and wheels are offered in a wide variety of sizes and types. Although there is no simple formula to follow in choosing the proper caster or wheel, the information shown below is intended as a guide to assist you in specifying, operating and maintaining casters for safety and maximum life. Please read this information carefully.
Load Weight & Wheel Size
The first consideration for caster selection is to determine the combined weight of the equipment and maximum load on this equipment. Generally, the greater the weight, the larger the wheel required for the caster. Larger wheels distribute weight and roll more easily over floor obstructions
As a general rule, hard tread wheels perform better on soft or smooth floors and soft tread wheels roll better on hard or rough floors including outdoor surfaces.
When choosing a wheel type, take into consideration all special floor conditions – tracks, gutters, grates, sills, elevator thresholds, seams and dock plates. The larger and softer the wheel, the greater the ability to roll over rails and similar obstacles.To protect floors from damage, choose softer cushion tread wheels. Solid Cushion Rubber, Advantage ™ TPR (thermoplastic rubber), High Modulus Rubber and-
Pneumatic Rubber wheels will provide quiet operation and maximum floor protection. Steel and Cast Iron wheels are not recommended for floor protection, but they are well suited for industrial applications.
Polyurethane wheels like PolyLoc™, Welded Disc Polyurethane and Moldon Polyurethane wheels are frequently an effective compromise giving moderate floor protection with greater load capacity
Wheel BearingsMonroe wheels are available with various types of bearings each best suited for various applications and uses. Below is basic information about each of these wheel bearings.
Sintered Iron BearingAn economical, oil-impregnated bearing suited for light loads or heavier loads that are stationary most of the time
Plain BearingWheel bearing bore riding directly on the spanner bushing and/or axle.
Ball BearingRecommended for loads where maximum rolling ease is required. They require less effort to start rolling and keep rolling than other bearing types
This bearing carries greater loads than same size ball bearing. Well suited for heavier, industrial uses
An economical bearing well suited to conditions of frequent exposure to water,steam cleaning, salts, brine and corrosive conditions
Unusual/Special Operating conditionsOften unusual operating conditions require selection of casters and wheels with special features. Listed below are several guidelines for selecting casters for special conditions
