Compact (toothed belt)-AXC

Principle
The AXC-Z modules from NTN-SNR are compact belt modules with integrated guidance and drive. These modules are multifunctionally applicable, from a single axis to a complete XYZ system.

Profile
The AXC program consists of 5 profile sizes. The profiles are designed in such a way that very high rigidity is achieved in combination with a compact build.
The available options are: 40×40, 60×60, 80×80, 100×100, and 120×120.

Drive
AT and STD belts, reinforced with steel cords, are used for drive. These belts are known for their high power transmission capacity. By pre-tensioning the belts on the module, high accuracy is achieved without the risk of belt skipping. The belts have a parabolic tooth profile, which helps reduce noise.

Guidance
For each AXC module, you can choose between using guide rollers or rail guidance with ball chains. Guide rollers are mainly used for high speeds and light loads or in heavily contaminated environments, while rail guides are designed for heavy loads and moments. Standard AXC modules are equipped with carriage systems using ball chain technology. This makes them maintenance-friendly and quiet, enabling high speeds and accelerations. The 45-degree ball arrangement allows the modules to be evenly loaded in all directions. The re-lubrication interval for ball chain guidance is between 1000 – 5000 km, depending on environmental conditions.

For AXC modules, you can choose between guide rollers or rail guidance with ball chains. Guide rollers are typically used in high-speed, low-load applications or in heavily contaminated environments, while rail guides are specifically designed for high loads and moments. By using only rail guidance with ball chains, a maintenance-friendly and low-noise movement is achieved. The re-lubrication interval for ball chain guidance is approximately 5000 km (depending on environmental conditions).

Options
In addition to the standard modules, a wide range of extra options is available. We offer a broad selection of mounting options, reducers, as well as coupling shafts and sensors. Depending on the environment, the modules can be equipped with various options, such as cover bands, side seals, coated guides, and stainless steel external bolts.
