Typical Applications

Workbenches - Shop Equipment - Kitchen Islands - Movie & Soundstage Equipment - Hospital / Medical Equipment

Any Application requiring the item to be held firmly in place.

Capacity up to 300 pounds per caster.
These institutional casters are ideal for any light duty application where the caster must be totally immobile when the caster brake is applied. Caster Model K3A has a unique brake which locks both the wheel and the swivel bearing at the same time. This "Total-Lock" brake insures that the swivel caster will not turn when the wheel is locked. This combination wheel brake and swivel lock is essential for safety in some applications - such as on worktables, tablesaws, and medical equipment. The Total-Lock brake is desireable whenever a brake is needed because it makes a swivel caster totally immobile. The wheels featured with Caster Model K3A are non-marking, and all except Polyolefin can be used on hardwood floors. Polyolefin wheels are best at reducing the risk of a flat spot occuring when loads are left standing for prolong periods. Gray Soft Rubber and Polyurethane wheels have a sealed precision ball bearing. They provide floor and cargo protection, quiet operation, and are very easy rolling. Try a set of 4 casters. You will be amazed at their performance!

Features:

Swivel Construction - Stamped steel. Swivel has double ball bearing.
Gray Non-marking Soft Rubber, Gray Polyurethane, Black/Gray , Blue/Gray and Red/Gray Polyurethane all have a precision sealed ball bearing ( PS ) shielded by full thread guards. Polyurethane on Aluminun Wheels have Ball Bearings ( B ) without thread guards. Polyolefin wheels have a plain bore ( no bearing ) ( P ).

Total-Lock Brake:

Combination Wheel Brake and Swivel Lock - This brake simultaneously locks the wheel and the swivel. One step on the activating pedal instantly locks the entire caster holding the equipment firmly in place. One step on the release pedal frees the swivel and wheel.

Use the Polyolefin ( Industrial Plastic ) wheel for "Standing Loads". Polyolefin wheels eliminate the possiblilty of a flat spot developing if the castered equipment is left parked for a prolong period.

You should never select on the basis of load capacity alone. Capacity ratings do not take into account the effort required to manually move a load. Capacity ratings are based on manual operation under ideal conditions. If these casters are going to be moved by mechanically powered equipment, consult us for a reduced capacity rating based on your application.
