Airtac HLQ Dual-Axis Precision Slide Table Cylinder HLQ20X40SAS
The AirTAC Airtac HLQ Dual-Axis Precision Slide Table Cylinder HLQ20X40SAS is a genuine HLQ slide-table cylinder, 20 mm bore: a double-acting dual-rod air cylinder integrated with a ball-bearing guide so the table travels straight with high rigidity and low deflection. It delivers about 236 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 HLQ Dual-Axis Precision Slide Table Cylinder HLQ20X40SAS
The HLQ20X40SAS is a double-acting dual-rod slide-table cylinder that combines an air cylinder with a ball-bearing linear guide for straight, low-deflection table travel. The 20mm bore and 40mm stroke yield moderate thrust across a compact range; the dual rod doubles the force and a floating joint prevents side torque from reaching the rods. The HLQ ball-bearing guide resists rust and blocks dust, making it suitable for environments where a cross-roller guide would be unnecessarily heavy.
This is a genuine AirTAC part with a standard sintered NdFeB magnet for position detection; compatible sensor switches are CMSH, DMSH, and EMSH, fitted into the magnetic-switch slots on the cylinder body. We confirm thrust, dimensions, and load-moment ratings from the AirTAC datasheet or 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
Bore 20 is a mid-size option in the HLQ family; larger bores add push for heavier workpieces, smaller bores save air when less force is needed. Select HLQ ball-bearing for anti-rust, dust-proof guidance; choose HLS cross-roller for maximum rigidity, HLH for multi-port precision assembly, or HLF for a lower body profile. The AS adjuster places an adjustable rubber stopper on the extension side only, useful when the retract position is set by a fixed fixture or bumper. Thread is PT (tapered). We route allowable load and moment sizing to the published tables and deflection curves and confirm the exact numbers before you order.
Applications
Extend-Positioned Probe
Drives a test probe onto a contact pad with the extension-side rubber stopper setting the exact touch-down position for repeatable measurement.
Part Pusher to Fixture
Pushes a small component into a clamping fixture; the extension-side stopper controls the push distance precisely while retraction runs to the standard bumper.
Dispensing Head Traverse
Moves a dispensing valve between two fill stations with guided straight travel; the extension stopper sets the dispense-end position for each shot.
FAQ
What does AS mean in HLQ20X40SAS?
AS means the adjustable rubber stopper is on the extension side only. The retraction end uses the standard bumper. This suits applications where the extend stroke needs precise end-position control and the retract position is governed by a fixture or fixed stop.
What air preparation does this cylinder require?
Use filtered compressed air at 40 um filtration. Operating pressure for bore 20 is 0.15-0.7 MPa (22-100 psi), and maximum working pressure must never exceed 0.7 MPa. Keep speed at or below 500 mm/s with meter-out flow control.
