6 inch heavy duty PU swivel caster.
The steering end of the warehouse standard: a 150 x 50 mm polyurethane-on-cast-iron wheel on a swivel fork specified for loaded carts, platform trucks and roll cages.
Six inches is the size warehouse equipment converged on because the physics works: the wheel climbs joints and dock plates at a shallow angle, keeps rolling resistance low under load, and still leaves the equipment stable. This swivel model pairs with the 6 inch rigid for the classic platform-truck layout, or runs as an all-swivel set on roll cages that must spin in lifts and aisles.
The swivel raceway is the component that decides this model's service life. The quotation states the raceway construction and whether it is hardened, because a soft raceway under a 150 mm wheel's leverage brinells quickly — and the first symptom, a caster that will not trail straight, is usually blamed on the operator.

What the sample verifies
Before bulk production, the production sample of this model is checked against the locked specification: wheel diameter and — critically — wheel width measured, tread hardness verified, bearing type confirmed, fork and plate thickness measured, and load performance tested per the stated convention (EN 12532 / ANSI ICWM). The approved sample becomes the reference for the shipment, and the order carries batch traceability back to it.

About this model
Which tariff heading does this size fall under?
At 150 mm diameter and 50 mm width it sits outside the 8302.20 definition and classifies under 8716.90.30 — see the tariff guide.
All-swivel or two-and-two for roll cages?
Roll cages that must rotate in lifts usually run all-swivel; platform trucks that travel distance run two-and-two. State the equipment in the RFQ and the quotation will follow the layout.
Can it match our existing plate pattern?
Send the pattern dimensions and the quotation locks to them, subject to sample confirmation.
Need this caster under your own brand?
Private label, custom packaging and carton marks are available across the range — mention it in the RFQ and the quotation will include the branding steps.
