Ultra Series Roller Chain

Engineered for Maximum Fatigue Life and Load Endurance

Rexton® Ultra Series represents the pinnacle of our roller chain engineering. Designed for the most demanding industrial applications, it delivers unmatched fatigue resistance, shock absorption, and strength.

Every component is manufactured and assembled with precision, pushing the boundaries of performance while remaining within ANSI/BS standards.

Backed by decades of field-proven performance and rigorous laboratory testing, the Rexton® Ultra Series consistently surpasses competitors’ high-performance roller chains in durability and reliability.

Key Features

Maximized Plate Dimensions

Plate height and thickness are pushed to the upper limit of ANSI/BS standards – boosting strength without compromising compatibility.

Through Hardened Pins

Pins are fully hardened throughout, providing greater resistance to shock loads and boosting the chain’s ultimate tensile strength.

Quad-Rivet Pins

Enhances structural rigidity, reducing component movement and wear—resulting in extended service life and higher operational reliability.

Up to 30% Higher Load Capacity

On average, Ultra Series chains provide a 30% increase in maximum allowable load compared to our standard roller chains in the same size class.

Advanced Manufacturing

Precise Pitch Hole Production

Enhances surface finish and dimensional consistency of plates and components.

Ball Drifted Pin Holes

After heat treatment, pin holes are ball drifted to refine pitch accuracy and maintain consistent engagement with sprockets.

Strict Tolerances Across All Components

All parts are produced with high accuracy for improved chain stability, smoother operation, and extended life.

Important Note: Only press-fitted connecting links are to be used with the Ultra Series chains. This design choice is intentional to preserve fatigue strength. Do not enlarge holes on the connecting link plates under any circumstances.

Rexton® Ultra Series chains are also available in heavy-duty variants (H) with thicker plates, and straight sidebar design.
