Heavy Roller Chain

Product catalog summary

Overview: The document provides technical specifications for various types of heavy-duty roller chains, specifically the 'H' type, which are designed for increased capacity and reduced fatigue failure. These chains are compatible with standard sprockets, except for multiple strand chains.

Specifications: The document lists detailed dimensions and mechanical properties for different chain models, including pitch, roller diameter, pin diameter, plate thickness, tensile strength, maximum allowable load, and average chain weight. Each chain type is identified by a specific code (e.g., SY 50-1 H, SY 60-2 H).

Key Parameters: - Pitch (P): Varies from 15.875 mm to 76.20 mm. - Average Tensile Strength: Ranges from 36.30 KN to 2,178.00 KN. - Maximum Allowable Load: Ranges from 7.22 KN to 255.00 KN. - Average Chain Weight: Ranges from 1.20 kg/m to 91.82 kg/m.

Design Considerations: - 'H' type chains have thicker link plates for enhanced capacity. - Single strand 'H' type chains are compatible with standard sprockets. - A 35% reduction in fatigue strength is noted when a single pitch offset link is used.

Connecting Links: - 'Clip' style for sizes 50 H, 60 H, 80-1 H, 80-2 H. - 'Through S pin' style for sizes above 200 H.

Usage Recommendations: The document emphasizes the importance of using the correct sprocket type and highlights the increased link plate thickness for improved durability.

Heavy Roller Chain ANSI | Single Pitch | Heavy Duty | H “H” type roller chains have increased link plate thickness to provide greater capacity without fatigue failure. The link plate thickness is that of the next larger size chain. Single strand roller chains of “H” type run on standard roller chain sprockets. Average Maximum Average Tensile Allowable Chain Strength Load Weight Connecting links are “clip” style for sizes 50 H, 60 H, 80-1 H, 80-2 H. Connecting links are “through S pin” style for all sizes above 200 H. H type chains are designed to be used with standard sprockets. H type multiple strand chains are not designed to be used standard sprockets. Takes account of a 35% reduction of fatigue strength when a single pitch offset link is used.
