Ball-screw variants provide higher transmission efficiency and selected configurations offer up to a 35% duty cycle, while Acme-screw variants provide robust self-locking performance across a wide load range.
| Code | Lead Screw | Duty Cycle | Max Dynamic Force | Self-Locking Force | Screw Pitch | Free-Load Speed | Full-Load Speed | Max Stroke at Full Capacity |
|---|---|---|---|---|---|---|---|---|
| A | Ball Screw | 20% | 17,000 N | 20,000 N | 5 mm | 6.5 mm/s | 5 mm/s | 600 mm* |
| B | Ball Screw | 35% | 13,500 N | 15,000 N | 5 mm | 9 mm/s | 6.5 mm/s | 1,000 mm |
| C | Ball Screw | 35% | 10,000 N | 12,000 N | 5 mm | 14 mm/s | 9 mm/s | 1,000 mm |
| D | Ball Screw | 35% | 7,500 N | 10,000 N | 10 mm | 18 mm/s | 13 mm/s | 1,000 mm |
| E | Ball Screw | 35% | 5,000 N | 8,000 N | 10 mm | 28 mm/s | 20 mm/s | 1,000 mm |
| F | Acme Screw | 20% | 12,000 N | 15,000 N | 4 mm | 7 mm/s | 5 mm/s | 1,000 mm |
| G | Acme Screw | 20% | 10,000 N | 12,000 N | 8 mm | 10 mm/s | 7 mm/s | 1,000 mm |
| H | Acme Screw | 20% | 7,500 N | 10,000 N | 8 mm | 14 mm/s | 8 mm/s | 1,000 mm |
| I | Acme Screw | 20% | 5,000 N | 8,000 N | 8 mm | 23 mm/s | 13 mm/s | 1,000 mm |
| J | Acme Screw | 20% | 3,500 N | 5,000 N | 12 mm | 35 mm/s | 23 mm/s | 1,000 mm |
Choosing the correct LINACT-35 configuration: Higher-force variants generally operate at lower speeds, while faster variants provide lower maximum force. Ball-screw configurations B to E offer a higher duty cycle of up to 35%, while Code A and the Acme-screw configurations operate at 20%.
The required actuator should therefore be selected according to the actual combination of load, speed, stroke, duty cycle and application requirements, rather than load capacity alone.
*Code A provides its full 17,000 N dynamic load capacity up to a 600 mm stroke. For strokes from 601 mm to 1,000 mm, the catalogue specifies a reduced maximum force of 14,500 N. Performance values are based on testing with a stable power supply at an ambient temperature of 20°C.
Fully Extended & Fully Retracted Lengths
The LINACT-35 Linear Actuator is built to specification, and its overall installation length depends on the selected stroke, performance code and mounting-end configuration. The dimensions below provide reference installation lengths based on the LINACT-35 CAD configurations shown.

A = Stroke Length | B = Fully Retracted Length | C = Fully Extended Length
The stroke length is the actuator travel. Fully retracted and fully extended lengths are measured centre-to-centre between the actuator mounting points.
Reference CAD Configurations:
50–600 mm stroke: F07 / R02 mounting with Ø30 mm rod
700–1000 mm stroke: F02 / R02 mounting with Ø35 mm rod
| Stroke Length | Fully Retracted Length* | Fully Extended Length* |
|---|---|---|
| 50 mm | 300 mm | 350 mm |
| 100 mm | 300 mm | 400 mm |
| 200 mm | 400 mm | 600 mm |
| 300 mm | 500 mm | 800 mm |
| 400 mm | 650 mm | 1050 mm |
| 500 mm | 750 mm | 1250 mm |
| 600 mm | 850 mm | 1450 mm |
| 700 mm | 1000 mm | 1700 mm |
| 800 mm | 1100 mm | 1900 mm |
| 900 mm | 1200 mm | 2100 mm |
| 1000 mm | 1300 mm | 2300 mm |
Alternative Configuration – Installation Length Adjustments:
The LINACT-35 is built to specification. Different performance codes and mounting ends may therefore require a longer installation length than the reference CAD configurations shown above.
- Performance Codes A and B: require an additional 30 mm installation allowance.
- Stroke 301–600 mm: requires an additional 50 mm compared with the basic stroke + 200 mm calculation.
- Stroke 601–1000 mm: requires an additional 100 mm.
- Front mounting ends F13 and F14: require an additional 40 mm.
- For F01–F12 configurations with strokes of 100 mm or less, the catalogue specifies a minimum installation length of 300 mm.
*The dimensions in the table correspond to the reference LINACT-35 CAD configurations shown above: F07/R02 with Ø30 mm rod for 50–600 mm strokes and F02/R02 with Ø35 mm rod for 700–1000 mm strokes. Final installation dimensions must be confirmed against the selected LINACT-35 configuration before manufacture or installation.

Typical Applications
The LINACT-35 Linear Actuator is suited to demanding applications requiring higher load capacity, robust construction and more advanced control or feedback options. Its configurable design makes it suitable for a wide range of industrial, agricultural, equipment and OEM applications, including:
- Industrial Machinery & Automation: Suitable for lifting, positioning, opening, closing and adjustment functions on production machinery, material-handling equipment and automated systems requiring higher force and reliable linear movement.
- Agricultural Machinery & Implements: The LINACT-35 can be used on heavy agricultural equipment for positioning, adjustment, lifting and opening mechanisms where higher loads or more demanding operating conditions are involved.
- Construction & Heavy Equipment: Suitable for engine hoods, access panels, service covers, lifting mechanisms and adjustment functions on construction, mining and earthmoving equipment.
- Lifting & Positioning Systems: The higher load capacity and wide range of control options make the LINACT-35 suitable for selected lifting and positioning systems where controlled electric movement is required.
- Patient Hoist & Assisted-Lifting Applications: The LINACT-35 has also been supplied for a patient-hoist application, demonstrating its versatility in specialised lifting systems. Suitability for any patient-handling or medical application must be evaluated against the specific load, safety, control and regulatory requirements of the complete system.
- Outdoor & Mobile Equipment: With IP66 protection, the LINACT-35 can be considered for machinery and equipment exposed to dust, moisture and demanding outdoor operating environments.
- Position-Controlled Systems: Feedback options including Hall Effect Sensor, analog signal and magnetic switches allow the LINACT-35 to be integrated into applications requiring position monitoring or controlled movement.
- Synchronized Multi-Actuator Systems: The LINACT-35 can be configured for synchronized control, making it suitable for selected applications requiring two or more actuators to operate together.
- Custom Machinery & OEM Applications: Because the LINACT-35 is built to specification, it is particularly well suited to OEM equipment and purpose-built machinery where the actuator needs to be matched to specific load, speed, stroke, mounting, feedback and control requirements.
Application selection is important: LINACT-35 configurations vary significantly in load, speed, duty cycle, mounting and control capability. Final actuator selection should therefore be based on the actual operating conditions and requirements of the complete application.
Mounting Brackets
Mounting Options
The LINACT-35 Linear Actuator offers a wide selection of front and rear mounting configurations, allowing the actuator to be matched to different machinery, equipment and installation requirements.
Available LINACT-35 front mounting options include F01 to F14, with a choice of through-hole, threaded and joint-bearing style connections. Rear mounting options include R01 to R07, providing additional flexibility when integrating the actuator into equipment or custom machinery.
Mounting-hole orientation can also be selected to suit the installation. Because the selected front and rear mounting ends can affect the actuator’s overall installation length, the final mounting configuration should be confirmed when specifying the LINACT-35.
