Modular Kitchen Caster Model 3 Features:

Modular Kitchen Caster capable of using all fastening options seen on this page! Stem and Plate!

Swivel Construction – Stamped steel. Swivel has double ball bearing with hardened raceways. Metal cover shields swivel bearings from dirt and dust.

Our kitchen catalog includes kitchen equipment, shelving, and table casters built to endure exposure to water, soap, and various chemicals. Here’s a snapshot of some of our most sought-after casters for restaurant and kitchen use.

But that’s not all. We have an extensive inventory catering to kitchens and restaurants, with more options not yet listed online. If you can’t find what you’re looking for or have any questions, please don’t hesitate to get in touch. We’re here to assist you.

Threaded Stem Casters should NOT be used as a “Leveling Device”! The weight is supposed to sit at the bottom of the stem on the swivel bearing. A properly installed threaded stem is fully supported the length of the stem.

When you put your mouse over the words in the wheel description column you see a picture of the wheel. Click on the part number in the Swivel and Rigid columns to see the complete caster.

We do NOT include mounting Hardware.

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.
