Stoltz Industries Non-Marking/Polyurethane Rollers

Stoltz Industries Non-Marking Polyurethane Rollers: Purpose-Built for Boat Trailers

When it comes to protecting your boat during transport, loading, and launching, few components matter more than the rollers on your trailer. Stoltz Industries has built a well-earned reputation as the go-to source for non-marking polyurethane rollers, offering a product line that marine enthusiasts and trailer manufacturers trust to safeguard hulls and simplify every trip to the water.

Why Polyurethane — and Why Stoltz?

Stoltz Super Rollers are made of polyurethane, specifically designed to replace rubber and PVC rollers that need frequent replacement. Rollers made of PVC and rubber are sometimes marketed as having qualities similar to polyurethane, but the material differences are far greater — although Stoltz Super Rollers may represent a larger initial investment, their superior durability makes them the more economical choice over the lifetime of a trailer.

Unlike traditional rubber rollers that can crack, mark, or wear down over time, Stoltz rollers are non-marking, UV-resistant, and designed to withstand harsh marine conditions. The chemical resilience is equally impressive: the roller material is unaffected by grease, oil, gasoline, exhaust fumes, salt, and similar substances. Just as importantly, Stoltz rollers will not “flat spot” even after months of storage — a common failure point with rubber alternatives.

A Comprehensive Lineup for Every Hull Type

Stoltz Industries offers one of the most complete selections of polyurethane boat trailer rollers available. Keel rollers are available in sizes ranging from 4" to 18" , ensuring compatibility across everything from small fishing boats to larger recreational vessels. The lineup also includes bow stop assemblies, V-rollers, semi-V rollers, slotted-channel rollers, skid pads, and end caps. Specific product series include the RP-4, RP-444, RP-8, RP-12, and the ULT series of bow stop assemblies — each engineered for a specific trailer bracket geometry and shaft size.

Stoltz Super Rollers reduce the effort needed for boat launching and retrieval by spinning freely and decreasing drag, eliminate the need to submerge the trailer to float off the boat, and serve as a buffer between the boat and trailer by shifting weight to the shock-absorbent rollers, thereby reducing damaging friction.

A key structural advantage over competing products is the one-piece polyurethane construction: Stoltz rollers have no bushings to pop out , while also being shock-absorbing and extremely cut-resistant. This integrity is critical in demanding salt-water environments where hardware failures can sideline a trailer prematurely.

American-Made Quality

All Stoltz products are designed and manufactured in Marshfield, Wisconsin, U.S.A. That domestic production translates directly into consistent material quality and reliable dimensions — important when fitting rollers to specific bracket widths and shaft diameters. Many boat manufacturers recommend better protecting one’s investment with trailer improvements, and Stoltz Super Rollers deliver long-lasting performance for the lifetime of a trailer.

Whether you’re upgrading a factory bunk trailer, replacing worn rollers on a roller trailer, or outfitting a custom build, Stoltz Industries’ non-marking polyurethane rollers offer a proven, hull-safe solution that holds up season after season.
