Stem Model G15 have the highest capacity ratings of all our model stem casters. Most of the time G15 stems are bought with a threaded stem. Caster City offers ¾” and 1” diameter threaded stems. The weight on a stem caster with thread is presumed to be supported on the top of the turn bearing, not on top of it on the thread stem. This means this stem caster was not built to be used as a leveling device. It is recommended you fully thread this caster to your application. Plain round stems are the other type of stem available with G15 Stems. Plain round stems are held inside tubing by drilling a hole through the tubing and the stem, followed by installing a bolt through the cross hole. They include: : ¾”, ⅞”, 1”, and 1-⅜”. G15 should be used only in hand powered applications. They are ONLY crafted in a swivel caster design. There is no lock or rigid option. All the same, a wheel brake can be provided but keep in mind that these casters are not built to hold weight on an slope.

Soft gray rubber wheels like the “RF” caster wheel are non-marking rubber tires that are injection molded to an industrial plastic center. This caster wheel is 1-¼” wide and is designed to use a ⅜” axle.This caster wheel has a durometer of 90-95 A which assists in vibration and noise dampening. This gray soft rubber caster wheel is assembled with a sealed precision ball bearing that is further guarded by two plastic spanner bushings which also act as thread guards, rotating against the axle and further protecting the bearing from direct water or chemical exposure. These caster wheels should not be left standing under load for extended periods as the tires may take a permanent “set” or develop flat spots.
