Cross-brand reference
L10 series — torque-class equivalents
Competing actuators in the same nominal torque class are listed below for engineering comparison. These are potential equivalents, not drop-in replacements: each brand uses its own housing and mount dimensions, so compatibility must be verified against drawings and application requirements before ordering.
| Nominal torque (Nm) | Helac L10 size | HKS | Sungji (SJH) | Moveco |
|---|---|---|---|---|
| 339 | L10-3.0 | M-DA-H 60 | SRA-090 | — |
| 1,074 | L10-9.5 | M-DA-H 80 | SRA-140 | — |
| 1,695 | L10-15 | M-DA-H 90 | SRA-160 | — |
| 2,825 | L10-25 | M-DA-H 100 | — | — |
- Nominal torque figures are Helac published values at rated pressure. The numbers inside HKS, Sungji and Moveco model codes are each manufacturer’s own size or bore designation, not torque values.
