Airtac HLH Side Rail Type Precision Slide Cylinder HLH20X40-S
The AirTAC Airtac HLH Side Rail Type Precision Slide Cylinder HLH20X40-S is a genuine HLH slide-table cylinder, 20 mm bore: a double-acting dual-rod air cylinder integrated with a miniature linear roller-ball guide so the table travels straight with high rigidity and low deflection. It delivers about 125.6 N of push at 0.5 MPa. A floating joint spares the rod from side torque; the magnet is fitted as standard.

About the Airtac HLH Side Rail Type Precision Slide Cylinder HLH20X40-S
A slide-table cylinder integrates an air cylinder with a linear guide so the moving table travels straight. The HLH20X40-S uses AirTAC's precision miniature linear roller-ball guide - the roller-ball integrated design delivers exceptional straightness and low deflection. The dual-rod construction doubles thrust for a given bore while the floating joint protects the rods from side torque. At bore 20 and 40 mm stroke, this model provides higher thrust for more demanding positioning tasks.
This is a genuine AirTAC part with a standard sintered NdFeB magnet for position sensing. Compatible sensor switches include CMSH, DMSH, and EMSH series, which mount in the body's dedicated slots. We confirm thrust, dimensions, and allowable load-moment from the published datasheet or on-page table on request.

Specifications follow the official AirTAC HL slide-table data. Max working pressure is 0.7 MPa. The table rides on an integrated linear guide — do not apply strong impact or large moment. Allowable load and moment are published as tables and curves, and overall dimensions vary per stroke — ask us and we confirm from the datasheet.
How to choose
Choose bore 20 when your application needs more push than smaller bores can deliver - a bigger bore means higher thrust without adding complexity. The HLH guide type suits applications where assembly precision and travel straightness are critical, and its three port groups and four-direction mounting offer flexible integration. Select a stroke within the bore's published table. Thread is PT (metric tapered). For load and moment sizing, we route you to the published Wmax and Emax tables and deflection curves.
Applications
Precision Assembly Stage
Mount small electronic components on the guided table for repeatable positioning during multi-step assembly with minimal deflection.
Pick-and-Place Traverse
Use the dual-rod slide as a horizontal pick-and-place axis to move parts between stations with consistent travel straightness.
Gripper Carrier
Carry a pneumatic gripper along the 40 mm stroke path, relying on the roller-ball guide for precise jaw alignment.
FAQ
Is the magnet optional on the HLH20X40-S?
No. The magnet is standard on every HLH slide-table model; the S in the code confirms it. You can use CMSH, DMSH, or EMSH sensor switches in the body's magnetic-switch slots.
What is the maximum working pressure for this bore?
Maximum working pressure is 0.7 MPa (100 psi). For bore 20, the operating range is 0.15-0.7 MPa (22-100 psi). Always meter out speed control to stay within 50-500 mm/s.
