How To Select A Caster

WHAT A CASTER DOES

Darcor casters are engineered for superior performance and mobility. Our stringent standards ensure strength, reliability, and extended life.

HOW TO SELECT THE PERFECT CASTER AND WHEEL

Darcor offers a large selection and for good reason. Choosing the correct caster for the job and the specific work environment dramatically increases the life and performance of the caster and enhances its ergonomic benefits.

First things first:
LOAD CAPACITY

This is the most important criterion for caster choice. In general, each caster should have the capacity to support one-third of the total load weight. That is because overloading, uneven floors and/or uneven load distribution may place a heavier burden on one or more casters.

To determine the required caster load capacity, add the weight of the load and the weight of the cart, then divide by three.

MAXIMUM MOBILITY

The larger the wheel size (and swivel radius), the greater the mobility. The type of bearing selected will also further improve mobility and reduce rolling resistance.

Darcor's Neoprene, Super Roll Neoprene, Solid Elastomer, and Polyurethane offer maximum mobility in any application they are required for.

Your choice should be determined by conditions in the work environment.

TREAD MATERIALS AND CASTER TYPES

Floor Conditions - Check for rough or uneven surfaces - joints, grates, potholes - and for oil, grease or chemicals, and note any carpeted areas.

Darcor Neoprene (D & SR) wheels are recommended for all types of floor conditions up to a load capacity of 600 lb. per caster. For moderate to heavy loads, Solid Elastomer (SE) wheels are an excellent choice. For the heaviest loads, choose Polyurethane or Steel wheels.

Environment Conditions - Check for dust, humidity and temperature extremes. Are the floors littered with debris or metal scraps?

Darcor Cartwashable™ Casters are ideal in areas with sprays or wash-down requirements. The sealed swivels and rust-inhibiting finish add extra life. Sealed swivels are also a good idea where there is grinding action, lint or dust. They are also quiet - a consideration in hospitals.

APPLICATION CONSIDERATIONS

Check the speed of your operation. Are you using towline vehicles or Automatic Guided Vehicles (AGVs)? Most casters are rated for "walking speed." Higher speed applications decrease their load capacity and can increase heat buildup.

Darcor Solid Elastomer (SE) wheels are the "high-speed" choice. In continuous use, they do not build up heat, are easy to maneuver with less effort and, because of their exceptionally low rolling resistance, actually extend the "in-use" time for battery-powered vehicles.
