LLZ belt linear drives

Roller linear guide with toothed belt drive for the carriage. Four profile size groups: 40, 60, 80, and 100. Max. feed force: 4.0 kN. Max. carriage load: 210 kg. Max. linear speed: 10 m/s. Positioning precision: 0.1 mm. Ideal for long strokes > 6,000 mm (max. 24 meters). Optional corrosion-resistant and low-noise LLN version.
LLZ belt linear drives
The guide body consists of a square aluminum profile with an integrated roller guide for the carriage. The carriage moves along it using an internal circulating toothed belt. At one end, there is a belt deflection system with an integrated coupling claw on both sides. On the opposite end, there is a plate with a belt tensioning device. This series allows for the creation of multi-section units with a length of over 24,000 mm.
Features of LLZ belt linear drives:
- Aluminum linear system with an internal roller guide for the carriage and a toothed belt drive.
- HDT toothed belt with steel reinforcement, guided inside the aluminum profile.
- The carriage is mounted on five rollers as standard, which can be adjusted and serviced in any position.
- The positioning system can be lubricated via two grease nipples on the slider.
- Low installation height, a major advantage of this linear drive.
- No backlash during direction changes.
- Suitable for fast positioning tasks.
- Ideal for both light and heavy loads.
- High repeatability with short cycle times.
- Linear axes can be easily combined into multi-axis systems using standard accessories.
- High linear speeds and accelerations.
- Long service life.
- Long stroke lengths up to 24,000 mm.
- Low maintenance costs.
- Quiet operation – low noise level.
- Temperature range: -25°C to +75°C.
- Available in food-grade versions.

Optional Versions of LLZ Belt Linear Drives:
- Corrosion-resistant version
- Low-noise and low-vibration version – LLN series
Low-noise and low-vibration linear drive versions: LLN60 / LLN80
- The belt is guided within the profile, making the system independent of the mounting position.
- The corrugated belt is self-running and features very low noise levels during operation due to a 45° tooth offset.
- Virtually vibration-free in transition sections.
