Standard single-strand roller-chain sizes for transmission and conveyor base-chain selection, with core dimensional and strength data from the connected internal catalogue.
Catalog-backed dimensionsThese sizes are useful both as power-transmission chains and as base chains for engineered attachments. Exact application rating still depends on speed, sprocket size, lubrication, duty cycle, shock and environment; ultimate-strength figures are not allowable working loads.
| ANSI | Pitch | Inside width | Roller Ø | Avg. ultimate strength | Avg. weight |
|---|---|---|---|---|---|
| 40 | 12.7 mm / 0.500 in | 7.92 mm / 0.312 in | 7.92 mm / 0.312 in | 17.66 kN / 3,970 lb | 0.42 lb/ft |

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.
Market-reference profileA 3/4 in pitch gripper-chain platform for incline, decline and side-grip conveying layouts. Final insert geometry, material and sprocket interface are confirmed against your conveyor drawing or sample.
