Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
Typical applications
What a linear stage is
A linear stage is a precision positioning axis in which a carriage or table moves along precision guides, driven by a ball screw, lead screw, belt or linear motor. Compared with a general rodless actuator, a stage emphasises straightness, flatness, accuracy and repeatability, with careful control of pitch, yaw and roll. Stages commonly integrate limit sensors, home sensors and linear or rotary encoders, and they can be stacked into XY, XYZ or gantry systems.
When engineers choose a linear stage
Choose a linear stage when the application depends on positioning accuracy and smooth guided motion, such as inspection, metrology, laser processing, semiconductor and laboratory automation. The trade-offs are cost and payload: precision guides and feedback add cost, and stage precision depends on mounting surface flatness. For general automation where a tenth of a millimetre is enough, a standard rodless actuator is usually more economical.
How to specify the PI (Physik Instrumente) L-417 high-load linear stage
Send these with your enquiry and an engineer can confirm the right L-417 high-load linear stage variant or an equivalent:
- Travel (mm)
- Accuracy, repeatability and resolution (µm)
- Straightness and flatness of travel (µm)
- Payload and moment loads (kg, Nm)
- Speed and settling time (mm/s, ms)
- Drive type: screw, belt or linear motor
- Encoder type, mounting surface and environment (cleanroom, vacuum)
Common mistakes to avoid
- Mounting a precision stage on a surface that is less flat than the stage
- Confusing repeatability with accuracy
- Ignoring thermal effects from the motor in precision work
- Stacking axes without considering the combined error
PI (Physik Instrumente) L-417 high-load linear stage: frequently asked questions
Can you help replace PI (Physik Instrumente) L-417 high-load linear stage or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including supply-network options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the PI (Physik Instrumente) L-417 high-load linear stage?
Motor-driven high-load stage with travel to 813 mm, 45 kg load capacity, up to 300 mm/s and repeatability to 1 µm. Published series figures include stroke 813 mm, linear speed 300 mm/s, repeatability 0.001 mm, payload 45 kg. It is made by HOERBIGER Holding (Positioning Division); Specify Motion can help source it or propose an equivalent.
Who makes the PI (Physik Instrumente) L-417 high-load linear stage?
The PI (Physik Instrumente) L-417 high-load linear stage is made by PI (Physik Instrumente) (HOERBIGER Holding (Positioning Division)) and is listed here for engineers comparing options. Specify Motion is not affiliated with HOERBIGER Holding (Positioning Division); brand names are used only to identify the product.
What is the stroke of the PI (Physik Instrumente) L-417 high-load linear stage?
The published series maximum stroke is 813 mm. Individual models and sizes in the L-417 high-load linear stage range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the PI (Physik Instrumente) L-417 high-load linear stage?
We can assess suitable replacement options. On published figures, Tolomatic TKS Dual Profile Rail Bearing and Tolomatic TRS Twin Profile Rail Stage are options to assess from our supply network. An engineer confirms the fit against your application before recommending anything.
What is the difference between accuracy and repeatability on a linear stage?
Repeatability is how closely the stage returns to the same position, while accuracy is how close it moves to the commanded position. A stage can be very repeatable but not accurate if the screw has lead error. Accuracy can be improved with linear encoders or error mapping.
When should a linear stage use a linear motor instead of a screw?
Linear motors suit high speed, high acceleration and smooth motion with no backlash or wear, especially on long strokes. Screw-driven stages suit higher static force, vertical axes and lower cost. Linear motor stages need a linear encoder and careful thermal design, so they are typically more expensive.
