Airtac HLS Precision Slide Cylinder HLS20X40S
The AirTAC Airtac HLS Precision Slide Cylinder HLS20X40S 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.

About the Airtac HLS Precision Slide Cylinder HLS20X40S
A double-acting dual-rod slide-table cylinder combines an air cylinder with an integrated cross-roller linear guide so the table moves in a straight line with high precision and rigidity. The HLS cross-roller guide provides the lowest deflection and highest load capacity of the AirTAC slide-table family. Dual rods double the thrust and a floating joint isolates the rod from side torque, protecting the guide bearings. At bore 20 and stroke 40 this basic-cushion unit suits longer mid-size guided travel where the standard bumper end-stop is sufficient.
This is a genuine AirTAC HLS part. A magnet is standard for position sensing with CMSH, DMSH or EMSH reed switches in the body slots. We confirm exact thrust, overall dimensions, allowable load and moment from the AirTAC datasheet or on-page specification 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 provides higher thrust than the smaller bores; selecting a larger bore increases push without adding guide length. The HLS cross-roller guide is the choice when rigidity and low deflection are key - HLQ gives anti-rust dust-proof ball bearings, HLH a miniature roller-ball guide with three port groups, and HLF a low-height body. Keep the 40 mm stroke within the bore 20 datasheet range. This model uses the basic bumper cushion; if you need end-of-stroke damping choose B for shock absorbers on both ends, BS for the extension side, BF for the retraction side, or A for adjustable rubber stoppers. Thread is PT; G or NPT are available on request. We verify allowable load and moment from the published Wmax and moment tables and deflection curves.
Applications
Pick-and-Place Stage
Drives a pick-and-place head over 40 mm of travel where cross-roller rigidity keeps the gripped part square during transfer.
Part Shuttle Slide
Shuttles small parts between loading and processing positions with straight guided motion and a repeatable bumper stop.
Tool Positioner
Positions a tool or fixture at a fixed extension point in a fixture build, the dual rod doubling thrust for firm clamping.
FAQ
Does this HLS20X40S include a magnet for position sensing?
Yes, the S in the code means a magnet is fitted as standard - it is not an option to decline. CMSH, DMSH and EMSH series reed switches mount in the magnetic-switch slots on the body for position detection.
What cushioning does the basic adjuster (blank) provide?
The blank adjuster code means the basic bumper cushion only - no shock absorber or rubber stopper. If end-of-stroke damping is needed, choose B for shock absorbers on both ends, BS for the extension side, BF for the retraction side, or A for adjustable rubber stoppers. Keep travel speed between 50 and 500 mm/s with meter-out control.
