Products: Screw supports


NIASA SH Series screw supports are a simple and economical solution for mounting a screw on a support and fastening it to any part of a machine. The turn of the screw moves its corresponding nut and with this the desired part of the machine moves (carriages, tables, etc.).

The screw supports are motorized in a very simple way, by motors or motoreducers in different configurations and with different speeds. The power transmission from the motor may be direct or by means of different gear solutions and toothed belts. Against other systems with pneumatic or hydraulic drives, their main advantages are: Greater movement and positioning precision.

Superior energy efficiency, as their parts offer high/very high performance, especially with the ball screws, low transmission ratios and high speeds.

Easier and faster assembly, since hydraulic or pneumatic groups are not required, just an electric motor mounted on the unit itself.

Greater reliability and duration, and less maintenance, due to the mechanical robustness and construction simplicity.

Lower size for the same load capacity.

They are also also characterized for offering an extensive range of:

Axial load capacities, from 2.5 kN up to 45 kN.

Nut advance speeds depend on the screw pitch and the transmission used. Trapezoidal and ball screws, depending on the performance required, precision of the desired movement and positioning, etc.

Fastening accessories and elements, for optimal adaptation to the most varied systems that may be designed.

Drives, with different reduction ratios and positions, which enables the best solution to be offered for any speed and configuration problem. Among these are the following as standard:

· Motors / In line motoreducers.

· Motors / Motoreduc. in parallel with the toothed belt.

· Motors / Motoreducers at 90o.


Materials and surface coverings, depending on the environmental conditions in which the unit will be installed.

Please do not hesitate to contact NIASA if you require screw supports (and their drive mechanisms) with specifications other than those covered in this chapter. The NIASA technical department will specifically develop the special units that best meet your requirements.
