When to use which system?
Lead screw drive
• High load capacity
• Ideal where precision and force transfer are important
• Well suited for vertical movements and heavy loads
• Ensures strong and accurate positioning
Toothed belt drive
• Ideal for high speeds and dynamic movements
• Offer high acceleration and repeatability
• Enables low-friction and quiet movement
Rack and pinion drive
• Offer a comination of high speed, precision and load capacity
• Particularly suitable for long distances and horizontal movements
• Allows smooth and strong movement along the axis
Linear axes with lead screw
The lead screw drive converts the rotary motion of a rotating lead screw into a linear movement. These systems facilitate linear adjustments through trapezoidal lead screws, available in various sizes, or high helix lead screws, which can be set in motion manually or electrically.
Max. travel speed up to 1.6m/min, depending on thread and load.
Stroke length freely selectable for any linear drive system. A plain-bearing-mounted lead screw has a maximum stroke of 1,500mm, a ball-bearing-mounted one 1,000mm.
Advantages
✓ Precise positioning
✓ High load capacity
✓ Compact design
✓ Low-friction movement

Different materials
Lead screw materials
For all drylin linear units, self-locking trapezoidal lead screws made of steel and stainless steel are used. Hard-coated aluminium and high helix lead screws made of stainless steel are also available upon request.
Shaft materials
From the standard range, shafts made of hard-anodised aluminium are most frequently used.
Bearing materials
All bearings are maintenance-free, with no need for external lubricants. The high-performance polymers are optionally available for applications with temperatures up to +180℃. FDA-compliant components are also available.
Linear axes with toothed belt
drylin linear axes with toothed belt drive are versatile for positioning and adjustment tasks. The drylin W profile guide serves as a lubrication-free linear guide, while a toothed belt acts as the drive. You can customize the stroke according to your needs. These axes are lightweight due to their polymer and aluminum construction, resulting in low inertia and high efficiency.
Whether you have limited installation space or require robust torque support, the linear units with toothed belt drive provide suitable solutions, both individually and in gantry designs. Additionally, all drylin toothed belt axes can be ordered with ready-to-connect configurations with drylin E stepper and DC motors.
Advantages
✓ Elastic force transmission
✓ Shock absorbing and quiet running
✓ Large shaft distances conceivable
✓ Lubrication-free
✓ Minimum maintenance

Linear axes with gear rack
Drylin cantilever axes are ideal for various positioning and adjustment tasks, offering high reliability and lightweight characteristics. They excel in applications involving vertical movements. When driven by a rack, they reduce the mass being moved. In terms of energy efficiency, power transmission to a rack is up to 30% more cost-effective than belt deflection. Additionally, these axes allow for the connection of grippers, part pickup, and movement.
Advantages
✓ High, constant stiffness of the axis regardless of the length of the stroke
✓ High precision
✓ High speeds possible
✓ Freely controllable installation position
✓ Long travels can be implemented
