NFTDJ Telescopic Servo Electric Cylinder
A multi-stage electric cylinder for machines that need extended travel within a compact retracted envelope. Compare the catalog drive configurations and define stage synchronization before selecting the assembly.
- Stage arrangements — The manual illustrates three-section/two-extension and four-section/three-extension layouts.
- Drive combinations — Catalog examples use a 10 mm lead, 200-750 W motors and 5:1, 7:1 or 10:1 reduction.
Configuration options
The manual illustrates three-section/two-extension and four-section/three-extension layouts.
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.
Stage arrangements
The manual illustrates three-section/two-extension and four-section/three-extension layouts.
Drive combinations
Catalog examples use a 10 mm lead, 200-750 W motors and 5:1, 7:1 or 10:1 reduction.
Load path
No radial load is permitted on the telescopic rod assembly.
Choose the stage motion
Synchronized lifting stages keep a consistent relative position but require the complete guided structure and travel envelope to be reviewed. Sequential extension has simpler construction but the individual stage position and timing differ.
- Catalog examples use a 10 mm lead, 200-750 W motors and 5:1, 7:1 or 10:1 reduction.
- No radial load is permitted on the telescopic rod assembly.

Catalog references apply to the stated configuration. Confirm tooling, sustained duty and calibrated measurement conditions.
Check the drawing for this product configuration
Confirm the mounting, tool interface and full movement envelope for the selected process configuration.
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.
Telescopic lifting: guide the platform independently
Nested actuator stages extend beneath a guided platform. The platform guides resist lateral forces; the telescopic assembly provides axial motion within a reviewed retracted and extended envelope.
- Confirm total travel and each stage stroke
- Select synchronized or sequential stage movement
- Review slenderness and vertical load restraint
Provide the inputs that define your configuration
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
- Total stroke, retracted length and individual stage travel
- Synchronized or sequential stage behavior
- Maximum-extension axial load and external guides
- Mounting, orientation and reviewed load restraint
The quotation confirms the mechanical, electrical, feedback and integration scope.
Product selection questions
Catalog references apply to the stated configuration. Confirm tooling, sustained duty and calibrated measurement conditions.
Support the workpiece and guide the tool independently. Review axial alignment, frame stiffness and transverse-load isolation.
Agree calibrated sensor ranges, loaded measurement conditions and trials with the actual parts. Catalog accuracy figures are configuration references.
Confirm the actuator, motor/drive, drawing, feedback, controller and tooling responsibilities for the supplied scope.
