Double-strand roller chains for higher load capacity or compact drive envelopes, available in common ANSI pitch families and attachment-ready configurations.
Standard family / configuration checkDuplex chain selection must preserve pitch, roller geometry and transverse spacing so it engages the mating sprocket correctly. For replacement orders, provide the exact ANSI size or a dimensional sample; for new designs, share torque, speed, center distance and service factor.
| Parameter | Value / option | Evidence / selection note |
|---|---|---|
| Common pitch families | 35-2 to 240-2 class | Confirm project scope |
| Strands | 2 | Duplex |
| Plate / pin execution | Standard or heavy-series options | By duty |
| Lubrication | Factory-applied / application-specific | By environment |
| Sprocket | Matching duplex sprocket required | Confirm tooth count and bore |
| Special attachments | Available by drawing | Attachment load requires review |
Do not select a gripper or attachment chain from tensile strength alone. Fit depends on sprocket engagement, pitch, width, attachment location, product contact geometry, conveyor path, lubrication and environmental conditions. For replacement work, a dimensioned sample or drawing is preferred.
Pair the gripper or conveyor chain with the correct base chain, attachments and sprocket where the application requires it.
