A Comprehensive Review Of Stem Casters

Before purchasing a replacement stem caster, it is essential to know the correct measurements. You can measure your stem’s diameter and base to determine the size of the grip ring. If you don’t know the exact measurements, you can estimate with a ruler.

Polymer stem casters

If you are looking for a polymer caster, you’ve come to the right place. These versatile units are compatible with steel and polymer stem caster posts and offer corrosion resistance, durability, and performance. These units are designed for medium-duty mobile applications and have various features, including bumpers and polyurethane flat wheel treads.

When buying a polymer stem caster, it’s essential to consider the mounting surface you will need it for. There are threaded stem casters and cylindrical ones. Thread pitch is the number of threads per inch, which can be difficult to gauge when ordering in metrics. In addition, the length of the stem does not include the overall height of the caster. Lastly, round stem casters are designed to accommodate scaffolding. They feature a hole in the stem secured with a cotter pin. These tend to be heavier duty than other types of stem casters.

Hollow kingpin casters

Hollow kingpin casters are versatile wheels for moving a wide variety of low-weight materials. They are commonly used on business machines, furniture, medical equipment, and electronics. The casters have a half-inch hole in the main swivel section and have a non-marking polyurethane tread. This type of caster is mounted using an m12 thread and nut.

Hollow kingpin casters feature a swivel-ball bearing to provide smooth swiveling and rolling. They are easily mounted with a 1/2″ diameter bolt and nut. A 1/2″-20 x 1-1/4″ long grade eight steel bolt and thin Nyloc nut are included with each caster. They have a high load capacity of up to 325 pounds each. If you’re looking for casters with a wide range of applications, consider the 3S Series.

Expanding adapter casters

Expanding adapter stem casters are designed to mount onto various tube fixtures. The rubber adapter expands when tightened with a hex nut, fitting snugly inside the tubing. Ideal for work tables, racks, and similar furniture, expanding adapter stem casters move items quickly. They are made of non-marking polyurethane and can be installed into either round or square tubing.

These casters are designed to be corrosion-resistant, and feature double ball hardened raceways. These casters are designed to withstand daily use while still providing superior maneuverability. You can easily select an expandable expanding adapter based on the inner diameter of the tube to be pushed into. They are typically slightly smaller than the listed size. For example, a standard one-inch adapter expands to 1.29″ when expanded.

Grip ring casters

Grip ring stem casters are very popular for industrial and institutional use. They feature a hood that acts as a fender and hides dirt and grime but does not add to the caster’s functionality. A threaded stem is a good option for industrial casters because it provides more secure mounting than other types of stem mount. In addition, while grip ring stems lose their grip over time, threaded stems always remain in place.

Grip ring stem casters are available in various sizes and weight capacities. The ring on the stem compresses when pressed into the mounting hole or socket. The ring then expands against the tubing walls, keeping it firmly in place. Grip ring stem casters have a range of weight capacities, from eighty pounds to one hundred and fifty pounds.
