Neff Press electric rail guided models deliver 1–30 tons of servo-driven force with a rail-guided ram that stays accurate under off-center loads. Get repeatable force and position control without hydraulics for close-tolerance dies, progressive dies, assembly, and other demanding production work.
These specifications describe our standard ESRG-Series rail guided models. Custom forces, stroke lengths, speeds, and frame sizes are available to suit your tooling, process, and production requirements. Standard models share a 10 in. adjustable stroke, 18 in. of daylight, a roller screw actuator, and 230V or 460V power. Rated force, ram speed, and bed area scale with the model.
| Model | Rated Force (tons) | Ram Speed (IPM) | Stroke | Daylight | Bed / Bolster Area (W × D) | Specification Sheet |

| ESRG-1 | 1 | 400 | 10 (adjustable) | 18 | 18 × 18 | |
| ESRG-2 | 2 | 400 | 10 (adjustable) | 18 | 18 × 18 | |
| ESRG-3 | 3 | 400 | 10 (adjustable) | 18 | 18 × 18 | |
| ESRG-4 | 4 | 400 | 10 (adjustable) | 18 | 18 × 18 | |
| ESRG-7 | 7 | 400 | 10 (adjustable) | 18 | 18 × 18 | |
| ESRG-10 | 10 | 400 | 10 (adjustable) | 18 | 24 × 24 | |
| ESRG-15 | 15 | 400 | 10 (adjustable) | 18 | 24 × 24 | |
| ESRG-20 | 20 | 240 | 10 (adjustable) | 18 | 24 × 24 | |
| ESRG-30 | 30 | 240 | 10 (adjustable) | 18 | 24 × 24 |
Daylight is the open height between the ram face and the bolster when the ram is fully retracted. It limits the combined height of your tooling and part.
Stroke is how far the ram travels, which sets how much of that opening the ram can work through.
Standard model forces, ram speeds, stroke, daylight, bed areas, standard features, and available custom options. PDF.
Precise servo motion with straightforward operator control.
Track every cycle and capture the data behind each part.
Designed and built in house for long service life.
Match the control package to how the press runs in your cell.
Shorten changeovers and move parts through the press consistently.
Adapt the press to your facility and operating conditions.
Interference fits, staking, crimping, inserting, and coining. The guided ram stays aligned under load, and force and position monitoring confirms every connection.
An index unit moves parts through repeatable steps such as small bending, keyway broaching, punching, and shearing, with the press cycle tied into the indexer through open architecture controls.
All-electric operation removes hydraulic fluid from the process, with repeatable force, cleaner operation, and process consistency for controlled environments.
Close-tolerance and progressive dies, hot stamping, and feed integration. The rail-guided ram holds alignment under off-center loads for repeatable forming.
Yes. Electric servo presses can hold peak force during a dwell phase for a set period. Because the motor uses electrical current to maintain that force, the press must be properly sized for the load and dwell time. Neff Press matches the motor, actuator, and gearing to the application so the press holds force safely without overheating.
Daylight is the open height between the ram face and the bed with the ram fully retracted. It limits the combined height of tooling and part. Stroke is how far the ram travels. Standard ESRG-Series rail guided models have 18 in. of daylight and a 10 in. adjustable stroke.
A rail guided press is a strong fit when your tooling puts off-center loads on the ram, or when you run close-tolerance or progressive dies that need the ram to stay aligned through the stroke. Share your application and our team can help you compare rail guided, column, and C-frame options.
Yes. Index units, shuttle systems, and feed integration packages are available, and open architecture controls with Ethernet and USB data packages let the press work with other equipment in the cell.
