CASTER TERMINOLOGY
LOAD (OVERALL) HEIGHT
The vertical distance between the floor and mounting point of the
equipment.
OFFSET or LEAD
The horizontal distance between vertical center lines thru the king
pin and wheel center.
SWIVEL RADIUS
The horizontal distance from the vertical center line of the king pin
to the outside edge of the wheel tread. This dimension specifies
the minimum distance required for the caster to swivel 360
degrees when mounted.
STEM CASTER versus PLATE CASTER
Stem casters are either threaded for mounting to a tapped mount-
ing plate or designed with a rubber expanding applicator for
mounting the caster to tubing. The construction of the applicator
is designed to provide maximum compression against the inside
of the tubing thus assuring a securely assembled caster.
Plate casters are provided with a plate pre-drilled with four bolt holes.
RIGID CASTERS
Plate models available from stock. Other styles available on
application.
BRAKE and NON-BRAKE CASTERS
Wheel brakes are available where required.
WHEEL BEARINGS
Wheel bearings may be either Sintered or Ball Bearing types.
SINTERED
A powdered metal, oil impregnated straight bearing that is self
lubricating, long lasting and impervious to heat and cold.
BALL BEARING
A flanged, permanently lubricated bearing, pressed in on each
side of the wheel hub.

CASTER SELECTION
LOAD WEIGHT
The heavier the load, the larger the wheel required for the caster. The weight of the load also influences the mobility of the wheel.
Weight requirements per caster may be specified as:
Light Duty.....0-80 Lbs. (0-35Kg.) Standard Duty.....0-200 Lbs. (0-90Kg.)
Medium Duty.....200-300 Lbs. (90-135Kg.) Heavy Duty.....300-500 Lbs. (135-225Kg.)
FLOOR CONDITIONS
The correct diameter of caster wheel is one that is large enough to pass over floor cracks and other similar obstacles. In choosing
the correct caster, consideration must be given to the type of floor such as ceramic, tile, vinyl, brick or cement. Surface conditions
are affected by grease, detergent, and heat. Autoclave requirements also bear on the choice of caster.
