Furniture Caster Types
Plate Type Furniture Wheels
have a round mounting plate with 3 screw holes. Outside diameter of mounting plate should not be larger than furniture leg diameter. This is a strong mounting wheel with center stem and screws holding caster in place. To replace this type of furniture wheel measure the diameter of the furniture leg that the round mounting plate will support and the center hole in the furniture leg. This center hole can be enlarged or plugged and re-drilled if necessary.
Stem Wheels with Grip Neck Sleeve
use a steel sleeve to hold them in place. A 3/8" x 1-9/16" hole is drilled in furniture leg. Sleeve is tapped in place, caster then snaps into sleeve. This style of caster became popular with the industrial revolution around the mid 1800's. If the sleeve is still in the furniture leg it is best to replace it with the new sleeve. If there is no hole, drill hole to accommodate sleeve and caster stem.
Threaded Stem Furniture Wheels
, with brass or porcelain wheels , have a round stem with coarse threads. Stem must fit snugly in leg for a proper fit. If stem is loose in furniture leg, caster can move so that it is not sitting properly, which puts undo stress on the caster. To replace know the diameter and height of the center hole. If hole in leg is to large plug with wood glue and dowel then re-drill hole. Height of center hole must be tall enough to accommodate threaded stem.
Cup Casters and Ferrules
with round or square cups, were made with and without wheels to finish chair and table legs. This very attractive style requires a tapered furniture leg. A snug fit is desired for stability - ferrule is attached to furniture with a wood screw. They were popular during the late Federal, Empire and Victorian eras.
