Airtac HLH Side Rail Type Precision Slide Cylinder HLH20X5-S
The AirTAC Airtac HLH Side Rail Type Precision Slide Cylinder HLH20X5-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 HLH20X5-S
The HLH20X5S is a double-acting dual-rod slide-table cylinder with a precision miniature linear roller-ball integrated guide. The 20 mm bore pairs with a short 5 mm stroke to deliver moderate thrust over a compact travel range, while the dual-rod design doubles the output force and the floating joint spares the rods from side torque. The roller-ball guide provides exceptional straightness and rigidity for a bore-20 body, and the unit mounts in four directions with three available port groups for flexible plumbing.
This is a genuine AirTAC part with a standard magnet fitted. Magnetic-switch slots on the body accept CMSH, DMSH, or EMSH sensor switches. We confirm the exact thrust, dimensions, allowable load, and moment values from the datasheet or the on-page spec 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
The 20 mm bore provides higher thrust than the smaller HLH bores (6 and 10) while keeping the footprint compact. Choose HLH when your application demands the best straightness and precision-assembly quality that the miniature roller-ball guide offers, versus the cross-roller HLS or ball-bearing HLQ alternatives. The 5 mm stroke suits very short indexing or clamping moves; longer strokes up to the bore-20 maximum are listed in the datasheet table. Thread is PT (BSPT); G and NPT variants are available under their own codes. Routing and load-moment sizing should be confirmed from the published tables and deflection curves on request.
Applications
Precision Assembly Stage
Indexes a small workpiece 5 mm into a precision press or measurement head where the roller-ball guide keeps deflection negligible under lateral load.
Short-Stroke Transfer
Shifts a part between two closely spaced nests in a pick-and-place cell, the dual rod ensuring stable travel without rod side-load torque.
Gripper Traverse Stop
Acts as a short, rigid stop for a gripper mounting plate that needs repeatable 5 mm positioning with four-direction mounting flexibility.
FAQ
What guide type does the HLH20X5S use, and how does it differ from HLS or HLQ?
HLH uses a precision miniature linear roller-ball integrated guide engineered for the best straightness and precision-assembly quality. HLS uses a cross-roller guide for maximum rigidity and load capacity, while HLQ uses a ball-bearing guide with anti-rust and dust-proof characteristics. HLH also mounts in four directions and offers three port groups.
What is the maximum operating pressure for the HLH20X5S?
Maximum working pressure is 0.7 MPa (100 psi). Operating pressure for the 20 mm bore is 0.15-0.7 MPa (22-100 psi). Proof pressure is 1.2 MPa (175 psi). Never exceed 0.7 MPa in service. Meter-out speed control should keep travel between 50 and 500 mm/s.
