Easily View & Download Hamilton's 2D & 3D CAD Models...

Hamilton Caster provides CAD Models of all its standard casters and wheels free of charge. The library is maintained in-house by Hamilton's engineering department. The adjacent video shows how to access the files. There are (3) ways.

1) Use the Finders by hovering over Casters or Wheels and select your desired attributes. Then click on the desired caster or wheel that best meets your selection criteria. You will then be given the option to view or download the CAD model. 

2) Browse our caster index or wheel index. and drill down through the product selections until you land on a specific product series. Then scroll down to the selection table and click on the specific caster or wheel part number. You will then be given the option to view or download the CAD model. 

3) Email your request to cad@hamiltoncaster.com  and we normally can provide a same-day response with the model. If emailing after 4:30pm eastern, the models will be sent the following business day before 10am.

Can't find the model you were looking for? Send an e-mail to cad@hamiltoncaster.com and we will do our best to reply back with the particular model you require.

Caster Size

Caster Size:

A loose term for classifying casters, based on the nominal diameter of the wheel. For example, a "6 inch caster" is any caster having a 6 inch diameter wheel. Measuring the wheel diameter includes tread (if applicable) from top to bottom.

Caster Size

Face (Tread Width):

Is the width of the wheel tread cross-section, measured at the base of the tread rather than at the point of floor contact.

Caster Size

Hub Length:

Is the measurement through the middle of the wheel (or hub) measuring from end point to end point (or bearing to bearing). You will want to make sure to measure through the center of the wheel and not just the outside because there will be space unaccounted for.

Caster Size

Bore Size:

The bore is the size of the hole in the center of the wheel where all the hardware fits into.

Product Configurator

Use our "Configurator Search Results" to narrow your search.

The two sample caster numbers below illustrate Hamilton’s significant, easy-to understand numbering system. The numbering system for wheels alone, ordered separately, is even simpler.

For example, a W-620-DB-1/2 defines a wheel only, size 6" diameter x 2" face, Duralast® type, with a 1/2" Precision Ball Bearing. Similarly, if you see W-1235-R-11/4-BS, you will soon know from sight that it specifies a wheel only, size 12" x 3-1/2" moldon rubber type, with a 1-1/4" roller bearing and bearing seals.

Most Hamilton Wheels are made available with a choice of bearing sizes or types to provide broad interchangeability and to meet the wide variety of needs in the marketplace. Hence it is usually necessary when ordering wheels separately from casters to suffix the desired bearing size. But you will rarely need to measure the bearing size of a wheel used in a Hamilton caster, because the complete replacement wheel number is given to you in most of the caster charts in this catalog.

What is our PRONTO® Quick Ship System?

Same-Day Shipping. Get Up and Running Faster.

Time is money, right? That's why we ship more than half of our standard casters and wheels the day you order them at no extra charge (for orders placed by noon EST). Your assembly line, warehouse or heavy-duty application depends on it.

Will my order ship in 24-48 hours?

It's easy. All casters and wheels marked with a red star (or black on our product selection tables) ship in 24-48 hours. All we ask is you order before noon EST, or we'll ship it the next day. All for no extra charge.

= Same Day Shipping

What about mixed, XL or custom orders?

We pioneered the industry's first quick-ship program in 1967 with one goal in mind: get it to you FAST. As such, we can only guarantee the service on items marked PRONTO. But we'll move heaven and earth to deliver extra-large volume, or mixed PRONTO/non-PRONTO orders as fast as possible.

Custom orders typically ship in 2-4 weeks, but can vary depending on the scope of work. Learn more about Hamilton's custom solutions

Polyurethane wheel hardness can be measured on two "Shores"; Shore A and Shore D. Shore A scale is generally used for the softer material while Shore D is used for harder ones.

Hamilton Caster primarily uses 3 main polyurethane hardnesses; 82-85A, 90-95A, and the extra hard 70D.

Wheel hardness

The harder the wheel material, generally the more capacity the wheel will have. Harder wheel materials traditionally are easier to roll. While softer wheel materials will handle floor debris better.

Durability, Rollability, Floor Protection, etc... Can be found on the part detail for each wheel under "Wheel Characteristics" as shown below.
