DIY Custom Casters
We’ve seen it countless times: An application that requires a unique threaded stem caster. Some of the most common examples of unique stems are metric threaded stems (which are very limited here), or special threaded stem lengths that are not standard items. In many of these cases, we are able to use a hollow kingpin caster (one with no stem or plate, but just a hole in the raceway) with whatever size or spec stem is needed in the form of a bolt from any hardware or fastener store.
As an example, the pictures below illustrate how we equipped a standard chrome-plated hollow kingpin caster with an extra long threaded stem for a special installation. It really is as simple as picking your own stem from the range of sizes available at any hardware store, and installing it through the hollow kingpin.
First, remove the wheel from the hollow kingpin yoke so that it does not interfere with the installation of the stem/bolt. The caster and axle setup will determine the tools you will need. Here is a hollow kingpin yoke with a total lock brake with the wheel removed:
Next, insert the custom stem you chose from underneath the swivel raceway as shown below.
Now, with the stem pushed all the way through the hollow kingpin, you can reinstall your wheel:
With your wheel reinstalled, all that’s left is to attach your caster to your application. If you used a hex-head bolt like we did in this example, you can use an open ended box wrench to tighten the stem while installing by holding the hex head located underneath the swivel raceway.
And just like that, you have created a custom caster for your application. If you would like to learn more about hollow kingpin casters, and other custom caster solutions, give us a call at 1-800-325-2753.
