Catena di trasmissione a rulli per impieghi gravosi

ANSI H-Series (Standard Heavy-Duty)

The ANSI H-series designates heavy-duty chains by an “H” suffix — 40H, 60H, 80H, etc. They share the same pitch and sprocket tooth profile as standard-series chains but carry thicker side plates throughout. The 80H-1, for example, achieves 56.7 kN ultimate tensile strength versus 35.8 kN for a standard 80 chain. All conform to ANSI/ASME B29.1 and can run on the same sprocket as standard chains of the same pitch, provided tooth clearance is confirmed.

Offset Chain

Heavy-duty offset catena a rulli uses an offset link adding half a pitch to the assembly, enabling odd link counts without a special connecting link. Ideal for confined centre-distance drives where sprockets sit close together. Built from medium-carbon steel — cold-pressed, bent after annealing, and impact-extruded at the pin hole for a smooth inner bore surface that resists metal fatigue. Widely used in mining, grain processing, and steel-mill applications.

Leaf Chain (BL Series)

BL-series leaf chains conform to ASME B29.8 and are engineered for moderate-to-heavy lifting — forklift masts, counterweight drives, and hoist systems. They carry no rollers; load transfers entirely through interlaced link plates and pins in combined tension and shear. The result is a very high tensile-strength-to-width ratio far exceeding a conventional roller chain of equivalent pitch, in a compact, low-profile assembly.

Catena silenziosa

Silent chains use multiple toothed link plates in closely spaced parallel rows that engage sprocket teeth with a smooth meshing action, eliminating the roller-contact impact that generates noise in conventional chains. Operating noise and vibration are dramatically reduced, while power density per unit of chain width exceeds that of roller chains. The flat back can be guided against a rail, making silent chains suitable for high-speed cam drives, timing drives, and noise-critical installations.
