The AirTAC Airtac HLS Dual-Axis Precision Sliding Cylinder HLS20X40ST is a genuine HLS slide-table cylinder, 20 mm bore: a double-acting dual-rod air cylinder integrated with a cross-roller 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.
The HLS20X40ST is an AirTAC HLS series slide-table cylinder: a double-acting, dual-rod pneumatic cylinder with an integrated cross-roller guide. With its 20 mm bore and 40 mm stroke, the table moves in a straight, low-deflection line, giving you higher thrust than smaller bores in the series while the dual-rod layout doubles the output force. The built-in floating joint means the rod takes no side torque from the workpiece, so precise guided travel is preserved even in assemblies that are not perfectly aligned. This is a genuine AirTAC part and the magnet is standard on every HLS cylinder, so position sensing is simply a matter of adding CMSH, DMSH or EMSH switches into the magnetic-switch slots on the body. Exact thrust, dimensions and allowable load/moment figures for the HLS20X40ST are shown in the on-page specification table and the datasheet - we are happy to confirm any of them 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.
A 20 mm bore sits in the upper range of the HLS series and delivers moderate-to-higher thrust than the 6-16 mm bores, making it a good pick when light-duty slides no longer push hard enough. If you need maximum precision and rigidity, the HLS cross-roller guide is the right sub-family; choose HLQ for an anti-rust, dust-proof ball-bearing alternative, HLH for a miniature precision guide, or HLF when reduced body height matters. The 40 mm stroke sits within the bore-20 HLS stroke table, and the T at the end of the code specifies NPT ports; a blank adjuster letter means the basic version with standard bumpers, while A/B-type adjustable rubber stoppers or shock absorbers are available as separate codes. For allowable load, moment and table deflection sizing, use the published tables and curves - or ask us to size it with you.
The cross-roller guide keeps the HLS20X40ST table straight and rigid under a 40 mm travel, so small assembly stations can press, insert or register parts with repeatable low-deflection positioning.
With dual-rod thrust, a floating joint and slots for CMSH/DMSH/EMSH switches, the table carries small parts between stations over the 40 mm stroke without side torque reaching the rod.
Mounted in any of three body orientations with two workpiece mounting options, the 20 mm HLS table traverses a gripper into and out of a fixture on a precise guided line.
HLS is the cross-roller slide-table series, 20 is the bore in mm, 40 is the stroke in mm, S confirms the magnet is fitted (it is standard on the whole HLS line, not an option), and T specifies NPT threads. Because there is no A/B adjuster letter, this is the basic version with bumper cushions; adjustable rubber-stopper and shock-absorber versions are available as separate codes.
The bore-20 HLS operates on air filtered to 40 um at 0.15-0.7 MPa (22-100 psi), with a maximum working pressure of 0.7 MPa and proof pressure of 1.2 MPa (175 psi). Recommended speed is 50-500 mm/s with meter-out control, and the allowable load and moment for your application should be confirmed from the published datasheet table and deflection curves before sizing.
