NTN-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 gures 1.1 to 1.4 show the basic structure of all NTN-SNR - Linear Axis and their main components:
Figure 1.1 ___ Structure Toothed belt axis
Figure 1.3 ___ Structure Rack-and-Pinion axis
Figure 1.2 ___ Structure Screw drive axis
Figure 1.4 ___ Structure Linear motor axis
1.1 Product features
Figure 1.5 ___ Prole with guiding rails Figure 1.6 ___ Prole with steel shafts
The base prole holds the guiding rails in case of Linear Guides or steel shafts in case of Track Roller Guides. The guiding rails are
screwed to the prole (Figure 1.5), the steel shafts are pressed into in the prole (Figure 1.6). The base prole is, with few exceptions,
an anodized aluminum prole. The Linear Axis of the AXBG series and special designs of AXS and AXLT series are based on steel
proles. The base prole largely determines the stiffness of a Linear Axis.

The slider unit is a complex assembly group which is usually made of an aluminum prole 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 prole grooves (Figure 1.8) to secure the customer’s
extensions.
The slider unit also contains the easily accessible service points for the lubrication of the guiding system and the drive elements
(Figures 1.12 und 1.13).
Depending on the series, various sealing elements (Figures 1.9 and 1.10) and the deection system for cover strips can be integrated
into the slider unit (Figure 1.11).
The product range of NTN-SNR - Linear Axis provides a variety of benets:
•Versatile applications by a complete product range from miniature
to heavy load axis in almost all industrial sectors
•Different driving and guiding systems combinable
•High load capacity
•High velocity
•Optimized aluminum proles in popular dimensions
• Standard grooves for sliding blocks
•Exclusive use of high quality components
•Flexible combination of Linear Axis including all connecting
elements
•Wide range of accessories for the drive assembly
• Delivery of pre-finished units and complete assembled
multi-axis-systems
•In addition, the compact design and the clear forms fulll the
technical criteria as well as providing high reliability
•Wide range of connecting elements and accessories
