Neff Press hydraulic bench models deliver 1–50 tons of force with three-sided tooling access from an open C-frame. Configure the press around your assembly, forming, or other compact production requirements.
These specifications describe our standard bench models. Custom dimensions and configurations are available to suit your tooling, process, and production requirements.
Standard D-Series bench models share an 18 in. daylight opening, a 7 in. throat, an adjustable 0.5–7 in. stroke, 150–3,000 psi operating pressure, and a 5 HP motor. Rated force and bolster size scale with the model.
| Model | Rated Force (tons) | Stroke | Daylight | Throat | Bed / Bolster (W × D × T) | Specification Sheet |

| D2-5M | 0.5–2.7 | 0.5–7 (adjustable) | 18 | 7 | 14.5 × 11 × 1.5 | |
| D4-5M | 1–4.7 | 0.5–7 (adjustable) | 18 | 7 | 14.5 × 11 × 1.5 | |
| D7-5M | 1–7.4 | 0.5–7 (adjustable) | 18 | 7 | 14.5 × 11 × 1.5 | |
| D12-5M | 2–12.4 | 0.5–7 (adjustable) | 18 | 7 | 14.5 × 11 × 1.5 | |
| D15-5M | 3–18.8 | 0.5–7 (adjustable) | 18 | 7 | 15 × 12.25 × 1.5 | |
| D15-5HS | 3–18.8 | 0.5–7 (adjustable) | 18 | 7 | 15 × 12.25 × 1.5 | |
| D25-5HS | 5–29.5 | 0.5–7 (adjustable) | 18 | 7 | 23.5 × 17 × 2 | |
| D40-5HS | 7–42.4 | 0.5–7 (adjustable) | 18 | 7 | 23.5 × 17 × 2 |
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 dimensions, ram speeds, pump flow, bolster layouts, and available custom options. PDF, 2 pages.
Repeatable cycles and straightforward operator control.
Built for the plant floor and simple installation.
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.

Press fits, staking, crimping, inserting, and coining. The open frame keeps the part and fixture easy to reach at the station.
An index unit moves parts through repeatable steps such as small bending, keyway broaching, punching, and shearing, with three sides of the bed free for the indexer.
Blanking, piercing, and forming small parts where the required force and die size fit a bench frame.
It depends on the operation (a press fit, staking, forming, or punching), the material, and the part geometry. Engineers usually start from a calculated or measured force and add margin. Send your part drawing, material, and operation, and our team can help confirm the tonnage and model.
Daylight is the open height between the ram face and the bolster with the ram fully retracted. It limits the combined height of tooling and part. Stroke is how far the ram travels. Standard D-Series bench models have 18 in. of daylight and a stroke adjustable from 0.5 to 7 in.
Yes. The C-frame leaves three sides of the bolster open for indexers, slides, and feed integration packages, and the press can be configured with automatic cycles and custom PLC controls to work with other equipment in the cell.
The main factors are the force you need, the daylight and bolster size your tooling requires, the size and weight of your parts, and how the press fits into your cell. If your requirements outgrow a bench frame, a hydraulic floor model provides a larger working envelope.
