Rubber Caster Hub

What are rubber casters? Rubber casters are industrial wheels with rubber treads bonded to iron, steel, or aluminum cores, mounted in swivel or rigid forks. They provide excellent shock absorption, floor protection, and quiet operation on rough surfaces including concrete, asphalt, and outdoor terrain. Rubber casters are ideal for environments where noise reduction and vibration dampening matter most.

What mount types are available for rubber casters at CasterHQ? ›

CasterHQ offers rubber casters in four mount types: top plate (bolt-on), threaded stem (screw-in), grip ring stem (push-in), and expanding adapter (friction-fit for hollow tube legs). Top plate casters are available in multiple plate sizes ranging from the light-duty 2-3/8 x 3-5/8 inch stainless plate to the heavy-duty 4-1/2 x 6-1/4 inch industrial plate. Stem casters are ideal for furniture, racks, and equipment with existing sockets.

What is the difference between TPR, mold-on rubber, and hard rubber caster wheels? ›

Thermoplastic rubber (TPR) uses a gray rubber tread on a polypropylene core — lightweight, non-marking, and quiet on hard floors. Best for light to medium duty up to about 350 lb. Mold-on rubber uses a thicker black rubber tread permanently bonded to a cast iron core — handles heavier loads up to 600+ lb and absorbs more vibration. Hard rubber is a solid black rubber with no soft tread — highest load capacity in the rubber family but less shock absorption. Choose TPR for floor protection, mold-on for heavy industrial use, and hard rubber for maximum durability.

Which rubber casters are non-marking and floor-safe? ›

Gray TPR (thermoplastic rubber) casters are the most floor-friendly option — specifically designed to be non-marking on tile, hardwood, polished concrete, and epoxy. Stainless steel TPR casters are also non-marking and add corrosion resistance. Standard black mold-on rubber and hard rubber wheels may leave marks on lighter floors. If floor protection is a priority, choose gray TPR wheels.

What plate size do I need for my rubber casters? ›

Plate size depends on your equipment's bolt pattern. Common sizes: 2-3/8 x 3-5/8 inch (light-duty stainless, food service), 3-1/8 x 4-1/8 inch (standard light-duty institutional), 4 x 4-1/2 inch (medium-duty industrial, most common), and 4-1/2 x 6-1/4 inch (heavy-duty industrial). Measure the bolt hole spacing on your existing caster or equipment mounting plate to determine the correct size.

Does CasterHQ offer stainless steel rubber casters? ›

Yes. CasterHQ carries stainless steel rubber casters in two series: light-duty stainless with 2-3/8 x 3-5/8 plate (available with TPR or hard rubber wheels) and the Durastar S34 medium-heavy duty stainless series (available with TPR, rubber on glass-filled nylon, or Duratek rubber wheels). Stainless casters are built for food processing, pharmaceutical, washdown, and marine environments where corrosion resistance is critical.

Can I buy rubber caster wheels without the caster fork? ›

Yes. CasterHQ sells rubber replacement wheels separately in all constructions. Visit the Rubber Wheels section on this page to browse wheels without caster forks. Replacement wheels are available in multiple diameters and bore types for rebuilding existing casters or custom equipment builds.

From Our Engineers: Rubber Caster Selection Tips

Rubber is our most-recommended wheel material for noise-sensitive and rough-surface environments. Here’s what we tell customers:

Rubber tops out around 1,200 lbs per caster — If you need more capacity, switch to polyurethane casters which handle the same floor protection at 3–5× the load.
Rubber on iron core > solid rubber — The iron core adds rigidity and load capacity. Solid rubber wheels compress under heavy loads and develop flat spots over time.
Use rubber for outdoor and uneven surfaces — Rubber absorbs vibration from cracks, expansion joints, and debris far better than hard wheels like phenolic or nylon.
Temperature range matters — Standard rubber works from −40°F to 200°F. For cold storage applications, rubber outperforms polyurethane which can stiffen below 0°F.
