Browse CasterHQ's full selection of 12" x 6" casters and wheels. Every caster in this collection features a 12-inch wheel diameter and 6-inch tread width — use the filters on the left to narrow by wheel material, mounting type, rig type, load capacity, and more. All products are backed by CasterHQ's ISO 9001:2015-certified quality standards and ship from our U.S. warehouse.
Selecting the right 12" x 6" caster starts with four key factors: load capacity (total weight ÷ number of casters × safety factor), floor type (hard floors favor polyurethane or nylon; rough surfaces favor rubber or pneumatic), environment (wet, high-heat, chemical-exposure, or cleanroom conditions dictate material choice), and mounting style (top plate, threaded stem, grip ring stem, or bolt hole). Larger wheels like this 12-inch diameter roll more easily over obstacles, floor cracks, and expansion joints — ideal for warehouse and industrial environments.
12" x 6" casters are widely used in extra-heavy industrial platforms, steel mill equipment, aerospace tooling, shipyard carts, and mining equipment. Whether you need swivel casters for maximum maneuverability, rigid casters for straight-line tracking, or braking casters for positional locking, CasterHQ has the right configuration for your application.
This collection includes 12" x 6" wheels in forged steel, ductile iron, polyurethane-on-iron, phenolic, and MC nylon. Not sure which material is right? Use the filters to compare options or contact our team at 1-800-544-8978 for expert recommendations.
CasterHQ is a direct-to-consumer industrial caster supplier with over 10,000 SKUs in stock. We offer free shipping on qualifying orders, same-day dispatch on most items, and a knowledgeable support team that can help you spec the right caster for any application. Every product meets or exceeds industry standards for load rating, bearing quality, and rig construction.
12" x 6" casters are commonly used in extra-heavy industrial platforms, steel mill equipment, aerospace tooling, shipyard carts, and mining equipment. The 12-inch diameter rolls smoothly over floor joints and debris, while the 6-inch tread width spreads load to protect floors.
We stock 12" x 6" wheels in forged steel, ductile iron, polyurethane-on-iron, phenolic, and MC nylon. Each material targets specific conditions — polyurethane for quiet floor-protecting rolls, rubber for shock absorption, phenolic for heat resistance, and steel or iron for maximum capacity.
Most setups combine two swivel casters (for steering) with two rigid casters (for tracking). Use four swivels for omnidirectional movement. Add brakes wherever positional locking is needed.
Capacity depends on wheel material, bearings, and rig — not just size. Use: (Total Load ÷ Casters) × Safety Factor (1.5–2.0). Filter by load capacity in the sidebar to find the right match.
