Wheels for the StemCaster Model 3

Stem Caster Model 3 Features

img Modular Stem Caster capable of using all fastening options seen on this page!
img Swivel Construction – Stamped steel. Swivel has double ball bearing with hardened raceways. Metal cover shields swivel bearings from dirt and dust.
img Axle – 3/8″ diameter bolt with lock nut.
img Center Pin 1/2″ diameter steel rivet
img Finish – external metal parts are Zinc plated.
img 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.
img Wheel Bearing – PS= Precision Sealed Ball Bearings, B= Ball Bearings, D= Delrin Bearings, P= Plain Bore, RB= Roller Bearing

Use the Polyolefin ( Industrial Plastic ) wheel for “Standing Loads”. Polyolefin wheels eliminate the possiblilty of a flat spot developing on the surfiace of polyurethane and rubber tires when the weight exceeds 2/3 of the rated capacity when the object is left parked most of the time.

Threaded Stem Casters should NOT be used as a “Leveling Device”! Capacity ratings are based on the weight being directly on the top of the swivel bearing, not somewhere above it on the threaded stem.

Metric Stem Option Now Available

TB – Top Lock Brake

PTB – Plastic Pedal Top Lock Brake

  • Swivel Radius for 3 inch PTB brake = 4-3/8″ ± 1/8″
  • Swivel Radius for 4 inch PTB brake = 4-1/8 ± 1/8″
  • Swivel Radius for 5 inch PTB brake = 4-1/2″ ± 1/8″

T-Nuts for Threaded Stems:

T-Nuts can be used to secure our threaded stem casters to wooden items. Here we show the typical use of the T-Nut for both a Horizontal and a Vertical Application.

In the Horizontal Application, you would drill a hole equal to the diameter of the barrel of the T-Nut and completely thru your wood. Hammer the T-Nut into the hole and thread your caster in from the bottom. This is the strongest mounting.

The Vertical Application is for attaching casters to the bottom of legs and into the end grain of the wood. This is not an exceptionally strong way to mount! Drill your hole equal to the diameter of the barrel of the T-Nut and to the depth of the length of the stem of the caster plus about 1/4″. Apply 2 part epoxy to the T-Nut for additional strength. Hammer the T-Nut into the hole and thread your caster in from the bottom. You must use epoxy as we have had problems with some woods where the nuts ( and the casters ) fall off.

Typical Applications:

img Material Handling
img Stocking Carts
img Food Service Carts
img Mobile Workstations
img Office Equipment
img Laboratory Equipment
img Bakery Equipment
img Moving Dollies
img Computer Equipment Stands
img Electronic & Diagnostic Equipment and Carts
img Computer Room Equipment
img Institutional Equipment

You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.
