Heavy Duty Short Pitch Roller Chains
|
25SH – 200SH · 5.09 kN – 506.1 kN
ANSI Compatible
SH Series roller chains deliver 25–35% higher ultimate tensile strength over standard ANSI roller chains by using through-hardened pins — hardened to the core, not just the surface. The result is a chain that handles peak shock loads and high cyclic tension without changing your sprocket, housing, or centre distance: SH chain dimensions are fully interchangeable with ANSI heavy series.

Chain Component Engineering
Connecting Link & Offset Link Options
For even pitch-count шынжырлар. Spring-clip or cotter-pin retention. One included per 10 ft box as standard. Allows field installation without press tools.
Use only when an odd pitch count cannot be avoided. Reduces tensile capacity at that joint — avoid wherever possible by specifying an even number of pitches.
Combines an inner link and offset link — stronger than the one-pitch variant. Preferred solution when an odd pitch count is unavoidable and joint strength must be preserved.
