NFT50 Folded-Back Servo Electric Cylinder
The NFT50 folded-back electric cylinder uses a ball-screw drive with the servo motor parallel to the cylinder. To select a configuration, match the motor, screw lead and mounting to your load, stroke and working cycle.
- Motor arrangement — Motor beside the cylinder; reserve lateral motor and service clearance.
- Stroke reference — 10–400 mm; final selection includes screw stability and mounting.
Configuration options
Motor beside the cylinder; reserve lateral motor and service clearance.
Working cycle
Approach, working movement, dwell and return reviewed together.
Mechanical integration
Mounting, load path and independent guidance defined for your machine.
Engineering support
Drive and feedback selection with NEFEIT.
Motor beside the cylinder. Axial drive at the rod.
A synchronous-belt transmission connects the parallel motor to the ball-screw drive. Check motor width, connectors and belt-service access.
- 10–400 mm; final selection includes screw stability and mounting.
- Choose 4 or 5 mm lead for greater thrust per motor torque; 10 mm lead for faster travel.
Images show the product layout and installation concept. However, the approved configuration drawing defines the assembly supplied.

| Motor power | 100 / 200 / 400 W |
| Performance | Reference |
|---|---|
| Base-body capability limit | 1.2 kN |
| Continuous thrust | Use the paired motor/lead rows |
| Mounting interfaces | Drawing-defined |
| Supply scope | Configured quotation |
| Lead (mm) | Motor (W) | Thrust (kN) | Speed (mm/s) | Motor (rpm) |
|---|---|---|---|---|
| 4 | 100 | 0.4 | 200 | 3000 |
| 4 | 200 | 0.8 | 200 | 3000 |
| 4 | 400 | 1.2 | 200 | 3000 |
| 5 | 100 | 0.3 | 250 | 3000 |
| 5 | 200 | 0.65 | 250 | 3000 |

| 10 | 100 | 0.15 | 500 | 3000 |
| 10 | 200 | 0.3 | 500 | 3000 |
| 10 | 400 | 0.65 | 500 | 3000 |
The body limit is a catalog boundary, not a continuous motor rating. Therefore, use thrust and speed from the same configuration row. Also check the transmission ratio and thermal duty.
Check the drawing for this product configuration
Choose the motor arrangement and mounting separately. For example, FA means front flange, FB means rear flange and LB means side flange. FC identifies a custom interface defined by the drawing.
FA — Front flange
FB — Rear flange
LB — Side flange
FC — Drawing-defined joint
Dimensions are in millimetres. Before machining mating parts, confirm the stroke, motor envelope and rod interface. The English drawing retains the source geometry and dimensions.
Compact positioning with external guidance
The cylinder rod moves a horizontal tooling carriage along its travel axis. Independent guide bearings support the carriage and resist transverse loads, keeping the rod aligned with the motion.
- Cylinder supplies axial carriage movement
- External guides support tooling weight and moments
- Size the drive for approach, dwell and return

Technical interfaces
Before you design mating parts, review the product drawing and available space with NEFEIT. The approved drawing defines the supplied configuration and mechanical interfaces.
Selection checklist
- Working and peak load, orientation and load direction
- Required stroke and approach, working and return speeds
- Cycles per minute, dwell and operating hours
- Mounting envelope, motor/drive and feedback requirements

Product selection questions
The body limit describes a catalog capability boundary. Continuous thrust depends on the paired motor, lead, transmission and operating duty.
Folded-back describes motor placement. Flange or custom mounting is selected independently against the configuration drawing.
The manual associates ±0.01 mm with additional linear feedback. Confirm loaded positioning, repeatability and measurement conditions for the selected system.
The manual describes a non-self-locking ball-screw drive. Review vertical holding, braking and mechanical restraint as part of the complete machine.
