drylin® R linear bearings are based on highly wear-resistant polymers developed especially for linear technology. The dimensions are compatible with standard ball bearings.
The special shape of the shaft guides and shaft bearings guarantee toughness and precision – even under extreme environmental conditions.

• Allows smooth and strong movement along the axis
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.
✓ Precise positioning
✓ High load capacity
✓ Compact design
✓ Low-friction movement
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.
From the standard range, shafts made of hard-anodised aluminium are most frequently used.
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.
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.
✓ Elastic force transmission
✓ Shock absorbing and quiet running
✓ Large shaft distances conceivable
✓ Lubrication-free
✓ Minimum maintenance
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.
✓ 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
XY-tables for horizontal movement of automated machines such as assembly robots in production plants, milling tables or drilling tables. Robotic arms and other automated machines have limited range of motion while their bases remain fixed; XY-tables allow these bases to move horizontally in the X and Y directions.
✓ High precision, extreme stiffness and accurate alignment due to the single-piece carriage
✓ 100% lubrication-free and completely corrosion-free
✓ Accessories available (hand wheel, position indicator, etc.)
✓ Complete stainless steel solution available
Different outer diameters and handles available
For setting and direct reading of the carriage position
For attaching to the position indicator and subsequent clamping of the lead screw
For rotary transmissions of 90°
