Industrial caster wheels, organised the way buyers specify them.

Buyers arrive at industrial caster wheels from four different directions. Distributors arrive by product line, building a range their customers recognise. Equipment OEMs arrive by specification, matching a wheel to a machine they build. Importers arrive by application — the cart, rack or line the caster must serve. And replacement buyers arrive by measurement, matching what is already bolted to their equipment. This page is the map for all four routes.

Enter by material

• Polyurethane caster wheels — the indoor workhorse: load, floor protection, quiet.
• Rubber caster wheels — shock absorption, rough floors, institutional quiet.
• Stainless steel casters — washdown, food and corrosive environments.
• High temperature casters — phenolic wheels for heat processes, rated by bake test.

Enter by duty and function

• Heavy duty caster wheels — 4–8 in PU on cast iron, the core line.
• Leveling casters — mobility plus a levelling foot in one unit.
• Shock absorbing casters — spring isolation for fragile loads.
• Furniture casters — 75 mm light duty for furniture and fixtures.
• Pneumatic caster wheels — air-filled for rough ground (secondary line).

Enter by mounting or size

• Plate casters — four-bolt top plate, the heavy duty standard.
• Stem casters — threaded, grip ring and bolt-hole interfaces.
• 6 inch caster wheels — the warehouse workhorse size.

Enter by application

Workbenches and tool storage, shopping and logistics carts, gates and scaffold equipment each stress casters differently. The application pages — workbench casters, tool box casters, shopping cart casters, gate caster wheels — start from the equipment and work backwards to the specification. OEMs building something new start at custom caster wheels.

One discipline across the range

Whichever door you enter by, the process is the same: the specification is locked in writing (diameter, width, hardness, bearing, fork thickness, test method), a sample is verified against it, and bulk production follows the sample with batch traceability. That discipline — not any single product — is what CASTOVELLA sells, and it is why the range can span a 75 mm furniture wheel and an 8 inch extra heavy duty caster without the quality story changing.

The specification we lock before quoting

A quotation is only comparable when the specification underneath it is fixed. For this line — as for every CASTOVELLA line — the written quotation locks these six variables, and the production sample is checked against them before bulk production is approved:

• Wheel diameter and width — width is both a performance variable and the US tariff classification variable; it is measured on the sample, not copied from a catalogue.
• Tread material and hardness — stated as a Shore hardness range, so the bulk shipment can be checked against the approved sample.
• Bearing type — plain, roller or precision ball bearing, named on the quotation; bearing swaps are the most common silent downgrade in this industry.
• Fork and top plate thickness — measured in millimetres and stated, because fork flex is where cheap heavy duty casters fail first.
• Load capacity and test method — capacity per caster with the test convention named (EN 12532 / ANSI ICWM), never a bare number.
• Finish and hardware — zinc plating, stainless grade or coating stated per component, not per marketing photo.
