Technical basics Linear Axis Product features SNR Linear Axis are compact components which contain a combination of guiding and driving elements. The modular design and the ability to combine Linear Axis within a product line and various product lines allow the user to design a simple, time-saving and economical solution for linear movements. The use of high quality components guarantees a high quality and reliability of Linear Axis. The figures 1.1 to 1.4 show the basic structure of all SNR Linear Axis and their main components: Figure 1.1 — Structure Toothed belt axis Figure 1.2 —...

The slider unit is a complex assembly group which is usually made of an aluminum profile or consists of aluminum components. The carriages or track rollers are mounted to the slider unit. The slider unit also connects the drive elements with the guiding elements of a Linear Axis. At the top side of the slider unit are threaded holes (Figure 1.7) or profile grooves (Figure 1.8) to secure the customer’s extensions. Figure 1.7 — Slider unit with threaded holes Figure 1.8 — Slider unit with profile grooves Depending on the series, various sealing elements (Figures 1.9 and 1.10) and the...

Driving systems Depending on the series, SNR Linear Axis, can be be produced with toothed belt drive, screw drive, rack and pinion drive or linear motor drive. Toothed belt drive Linear Axis with toothed belt drive are suitable for fast handling and positioning applications. All axis are equipped with AT or STD toothed belt. These are extruded polyurethane belts with integrated steel cords. The AT toothed belts are carried out in the zero-gap shape. The use of black toothed belts prevents discoloration of the toothed belts under UV - radiation. These toothed belts are also characterized by...

Screw drive Linear Axis with screw drive can be equipped with ball screws (Figure 1.17) and with trapezoidal screws. Screw drives are especially suitable for high requirements for positioning accuracy and repeatability in combination with high rigidity of the driving element. The drive adaption can be done directly by coupling and coupling cone or with a deflection belt drive. Figure 1.17 — Linear Axis with screw drive In order to achieve a high velocity even at longer lengths, it is possible to equip the Linear Axis of the AXC and AXDL series with one or more sets of screw drive support...
