A linear axis is an automation component that moves a payload along a controlled straight path. Linear axes can use technologies such as toothed belts, spindles, rack-and-pinion systems or direct linear motors to create motion.
SCHUNK offers electrically driven linear axes using belt, spindle, rack-and-pinion and linear direct-drive technologies. The portfolio includes individual axes as well as components that can be combined into multi-axis automation systems.
A belt-driven axis can be a good fit when long travel and dynamic motion are priorities. A spindle-driven axis is often better suited to applications where controlled positioning and precision are more important. Final selection should also account for payload, forces, moments, cycle time and mounting orientation.
A direct-drive linear axis uses a linear motor to generate motion without a conventional belt or spindle transmission. SCHUNK offers several direct-drive families, including SLD, ELB, ELP, LDK, LDN and LDL.
A hydraulic pump moves fluid through the system. A hydraulic power unit is a more complete assembly that typically includes the pump, motor, reservoir, filtration, valves, and other components needed to generate and control hydraulic power.
Yes. SCHUNK describes its linear axes as modular systems that can be combined into complete solutions, ranging from individual components and pick-and-place units to pre-assembled multi-axis systems.
From a single linear motion axis to a complete multi-axis handling system, SCHUNK linear axes give machine builders and manufacturers a flexible platform for creating fast, precise and repeatable automated motion.
With belt-driven, spindle-driven, rack-and-pinion and linear direct-drive technologies available, SCHUNK provides solutions for applications ranging from high-speed assembly and pick-and-place to long-travel material handling and precision positioning.
Need help selecting a linear axis? PennAir can help evaluate your stroke, payload, speed, precision and application requirements to identify the right SCHUNK solution.
Choosing a linear axis is about more than stroke length. Payload, cycle time, acceleration, repeatability, mounting orientation, available space and the forces acting on the axis all affect the final design.
SCHUNK’s linear-motion portfolio includes several drive technologies, allowing the motion system to be matched to the actual needs of the machine.
Best suited for fast motion and longer travel distances.
Belt-driven axes are a strong choice when an application prioritizes high-speed positioning, dynamic movement and longer strokes.
Common applications include:
SCHUNK’s Beta series, for example, is available with a toothed-belt drive or spindle drive, allowing designers to select the motion technology that best fits the application.
Best suited for precise positioning and controlled linear movement.
Spindle-drive systems are often selected when positioning accuracy, rigidity or controlled movement takes priority over maximum travel speed.
They can be well suited for:
SCHUNK offers multiple spindle-driven product families, including Beta, Delta and Alpha configurations.
Best suited for highly dynamic, precise automation.
Linear direct drives eliminate traditional mechanical transmission components between the motor and load. SCHUNK offers several linear direct-drive families for applications requiring dynamic motion and precise positioning.
Options within the portfolio include:
SLD
A dynamic linear-axis platform designed to be configured around the application.
SLD Mini and SLD Midi
Compact linear direct axes designed for assembly and high-performance automation.
ELB
A short-stroke linear direct-drive axis with cross-roller guidance.
ELP
An electric linear axis with integrated controller and preloaded roller guidance.
LDK, LDN and LDL
Linear motor platforms available in compact, universal and flat configurations.
These options make it possible to select the physical profile and performance characteristics around the machine instead of forcing the machine design around a single actuator.
A strong option for long travel and demanding automation systems.
For applications requiring extended travel, SCHUNK also offers rack-and-pinion drive configurations within its linear-axis portfolio. The Gamma series can be configured with either a toothed belt or rack-and-pinion drive.
Potential applications include:
Linear motion rarely operates alone.
SCHUNK’s modular approach allows individual axes to be combined into larger automation systems, including pick-and-place units and pre-assembled multi-axis systems. SCHUNK also provides dedicated configurators for individual linear axes and complete axis systems.
That can make the platform a strong fit for:
X-Y Systems
Two coordinated axes for positioning across a working area.
X-Y-Z Systems
Three-axis motion for picking, placing, loading, dispensing or assembly.
Gantry Systems
Long-travel automation for transferring components between machines or processes.
Pick-and-Place Systems
Fast, repeatable movement between defined production positions.
Cuidado de máquinas
Automated loading and unloading designed to increase machine utilization and reduce repetitive manual handling.
There isn’t one “best” linear axis. The right solution depends on what the axis needs to do.
Start with these application requirements:
SCHUNK’s current linear-axis portfolio includes options with repeat accuracy ratings as tight as 0.01 mm, H1 grease versions and configurations for ISO 14644-1 cleanroom classes, depending on the selected series and configuration.
SCHUNK’s portfolio includes linear-motion solutions across a range of machine designs and automation requirements. Current product families include:
Not sure which family belongs on your machine? That’s where PennAir can help.
The linear axis is only one part of the motion system.
PennAir helps combine SCHUNK linear motion with other automation components to create a more complete solution, including:
PennAir is a SCHUNK distributor with experience supporting SCHUNK gripping and automation technologies.
Instead of selecting an axis based on one specification, our team can look at how the motion fits into the entire application.
