Telescopic Screw Drive S-TEG

Product catalog summary

Overview: The NEFF Telescopic Screw Drive S-TEG is an advanced drive unit designed for continuous torque and minimal clearance throughout its stroke. It is available in two versions: glide screw and ball screw, each with specific features and benefits.

Specifications:

Drive Versions: Glide screw version features Teflon-coated aluminum for reduced friction, while the ball screw version uses standard nuts for easy replacement.
Design Variants: Available as 'N' design (lifting screw) or 'VK' design (non-rotating), with optional safety nuts and integrated limit switches.
Connection Options: Standardized options for gear, toothed belt, or direct motor connection via adapter flange or coupling.

Technical Specifications:

Max Stroke Power: 16400 N for ball drive, 10500 N for glide screw drive.
Stroke Length: Up to 2400mm, extendable on request.
Stroke per Revolution: 10mm, extendable to 100mm on request.
Axial Clearance: 0.1mm for ball screw, max 0.4mm for glide screw.
Accuracy Classes: T7 (52μm/300mm), T9 (130μm/300mm), T10 (210μm/300mm).
Efficiency: 0.76 for ball screw, 0.21 to 0.68 for glide screw depending on stroke per revolution.
Idling Torque: 0.054 Nm for ball screw, 0.133 Nm for glide screw.
Max Drive Torque: 30Nm.

Product Variants:

S-TEG-N-VK: Available with adapter flange AF, High Speed Screw Jack G1, or Screw Jack M3, with optional translation ratios.

Ordering Code: The product code includes design, screw design, screw size, accuracy class, safety nut, stroke length, attached parts, limit switches, and special requirements.

NEFF Telescopic Screw Drive S-TEG 2-stage synchronously extending telescopic screw drive as glide screw drive version or as ball screw drive version. As proven “N” design version – “Lifting screw” - or as non-rotating variant of the “VK” design, optionally with safety nut and integrated limit switches. Standardised connecting options on request for gear, toothed belt or for the direct connection of a drive motor by means of a motor adapter flange or coupling. The different variants can be selected on the basis of the product code. General technical data: - The intelligent drive unit ensures continuous torque and clearance throughout the entire stroke. Reduced friction values due to Teflon-coated aluminium materials (glide screw version) The safety nuts for the glide screw version may optionally be set for fracture or wear. For the ball screw version, nuts from the standard product range are used, thus ensuring availability of stock goods and quick r
