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 rodless belt actuator is
A rodless belt actuator moves a carriage along an aluminium profile using a toothed belt driven by a pulley at one end. The load mounts on the carriage, which runs on internal bearings or profile rails, so the unit carries and guides the load. Because the belt does not whip like a long screw, stroke can be long, typically several metres, and speeds are high. Belt drives are less stiff than screws, so they suit fast transfer more than high-force pushing.
When engineers choose a rodless belt actuator
Choose a belt actuator for long strokes, high speed and lighter thrust loads, such as transfer axes, gantries and pick-and-place over distance. The trade-offs are stiffness, thrust and accuracy: belt stretch reduces stiffness and repeatability compared with screw drives, and vertical axes need a brake and careful sizing. For high thrust or tight positioning at short stroke, a screw rodless actuator is usually a better fit.
How to specify the Parker Hannifin HLR
Send these with your enquiry and an engineer can confirm the right HLR variant or an equivalent:
- Payload mass and moment loads (kg, Nm)
- Stroke (mm or m)
- Speed and acceleration (m/s, m/s²)
- Positioning repeatability (mm)
- Thrust force needed (N)
- Orientation and any vertical axis requirements
- Motor mounting, gearbox and environment
Common mistakes to avoid
- Forgetting belt tension and stretch when tight repeatability is needed
- Using a belt actuator for pressing or high thrust tasks
- Ignoring reflected inertia and gearbox ratio on high-acceleration axes
- Mounting the profile unsupported over long spans
Parker Hannifin HLR: frequently asked questions
Can you help replace Parker Hannifin HLR 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 Parker Hannifin HLR?
High-load belt-driven rodless actuator in sizes 070 and 080; series maximum 3,847 N load, 900 N thrust, 5 m/s and 3,500 mm stroke, IP40. Published series figures include force 900 N, stroke 3,500 mm, linear speed 5,000 mm/s, linear speed 5 m/s. It is made by Parker-Hannifin Corporation; Specify Motion can help source it or propose an equivalent.
Who makes the Parker Hannifin HLR?
The Parker Hannifin HLR is made by Parker Hannifin (Parker-Hannifin Corporation) and is listed here for engineers comparing options. Specify Motion is not affiliated with Parker-Hannifin Corporation; brand names are used only to identify the product.
What is the force of the Parker Hannifin HLR?
The published series maximum force is 900 N. Individual models and sizes in the HLR 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 Parker Hannifin HLR?
We can assess suitable replacement options. On published figures, Tolomatic B3W Belt-Drive Rodless and Tolomatic MXB Belt-Drive Rodless (MXB-U / MXB-S / MXB-P) are options to assess from our supply network. An engineer confirms the fit against your application before recommending anything.
How long can a belt-driven linear actuator be?
Belt actuators commonly reach several metres of stroke from one profile, and longer strokes are possible with joined profiles. The limits are profile stiffness, belt stretch, support spacing and the moment loads on the carriage. Long axes need regular supports along their length to avoid sag.
How accurate is a belt-driven actuator?
Repeatability on belt actuators is typically in the region of a tenth of a millimetre, depending on belt type, tension and load, which is coarser than screw drives. Accuracy is affected by belt stretch and pulley tolerances. For better accuracy, add linear encoder feedback or choose a screw drive.
