6 Inch Heavy Duty Rigid Caster – Aluminum Core PU Wheel with Galvanized Steel Plate, 600kg Load Capacity
Need a heavy duty fixed caster that goes exactly where you point it? This 6-inch rigid industrial caster features a polyurethane tread on an aluminum core, a non-swivel rigid bracket for straight-line stability, and a galvanized steel mounting plate rated for 600 kg per caster. The most cost-effective choice for towing, conveyor lines, and high-load applications.
Straight. Strong. No Drift.
Our 6-inch Heavy Duty Rigid Caster is built for one job—moving heavy loads in a straight line, reliably and without deviation. Unlike swivel casters, the fixed rigid bracket eliminates sideways drift, making it the preferred choice for towed carts, conveyor feeds, and assembly-line dollies where directional control matters.
The polyurethane (PU) tread is bonded to a precision aluminum core, delivering a quiet, non-marking ride on epoxy, concrete, and tile floors. The 5 mm thick galvanized steel bracket and top plate provide exceptional rigidity under dynamic loads, preventing flex even at maximum capacity.
Rigid casters are typically paired with two swivel casters on a four-wheel cart—giving you straight-line tracking from the rigid wheels and maneuverability from the swivels. As a factory-direct caster manufacturer, we deliver consistent quality at competitive pricing.

Pro Tip: Most 4-wheel industrial carts use 2 Rigid + 2 Swivel casters—the rigid pair provides directional stability while the swivel pair handles steering. This combination is the industry standard for platform trucks and assembly-line dollies.
High-temperature environments above ~80 °C (176 °F) – choose phenolic or steel wheels
Outdoor rough terrain / gravel / grass – pneumatic tires are more suitable
Prolonged direct sunlight / UV exposure unless UV-stabilized PU is specified
Slippery or icy floors – soft rubber provides better traction
Speeds exceeding 4–6 km/h – industrial casters are designed for controlled manual or slow-towed movement
Tight turning radius applications – rigid casters cannot turn; use swivel instead
Q: Can I use only rigid casters on my cart?
A: Technically yes, but the cart won't turn. For steerable carts, pair 2 rigid + 2 swivel casters (rigid at the rear, swivels at the front).
Q: Is the rigid bracket stronger than a swivel bracket?
A: Yes. The fixed design eliminates moving parts and rotational stress, making it inherently stronger and more durable under heavy loads.
Q: What is the bolt pattern? Will it fit standard mounting plates?
A: Top plate is 138 × 110 mm with bolt hole spacing of 105 × 80 mm and 13 mm diameter holes—compatible with most standard industrial mounting plates.
Q: Can I get this in swivel or brake versions?
A: Absolutely. We supply Swivel Rigid / Fixed nd Brake configurations. Contact us for volume pricing.
Q: What is the minimum order quantity (MOQ)?
A: Standard MOQ applies. Contact us for exact numbers based on your region and configuration mix.
