Airtac HLSL Precision Slide Table Cylinder HLSL20X40SA
The AirTAC Airtac HLSL Precision Slide Table Cylinder HLSL20X40SA 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. This is the symmetrical version. A floating joint spares the rod from side torque; the magnet is fitted as standard.

About the Airtac HLSL Precision Slide Table Cylinder HLSL20X40SA
The HLSL20X40SA is the symmetrical cross-roller slide table cylinder of the AirTAC HL series with a 20 mm bore and 40 mm stroke. A double-acting, dual-rod cylinder is integrated with a rigid cross-roller linear guide, giving the table straight, low-deflection travel and higher thrust than the smaller bores of the family; the dual rods double the output and the built-in floating joint keeps side load torque away from the rods. The A suffix adds adjustable rubber stoppers at both ends so the stroke ends can be fine-tuned and softly cushioned.
This is a genuine AirTAC part with the position-detecting magnet fitted as standard; the body carries magnetic-switch slots for CMSH, DMSH and EMSH sensor switches. Thrust, dimensions and the allowable load and moment data for this exact model are published in the on-page datasheet table, and we will confirm any figure from the datasheet 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 is the step up in the HLSL series when the 6 to 16 mm bores do not push hard enough; the exact thrust at working pressure is in the spec table, not to be hand-estimated. Within the HL range, choose HLSL for maximum guidance rigidity and precision from the cross-roller guide, HLQL when an anti-rust, dust-proof ball-bearing guide is preferred, HLF when installation height is tight, and HLH for ultra-fine straightness on miniature bores. The 40 mm stroke is a listed value in the 20 mm bore stroke table.
The A in this code means adjustable rubber stoppers on both ends - a middle option between the basic bumper version (HLSL20X40S) and the shock-absorber versions (B, AS/BS/AF/BF), useful when you want to trim the effective end position and soften light impacts. Ports are 1/8" and the blank thread code is PT, with G and NPT available. Route your load, moment and kinetic-energy sizing through the published tables and curves - we are happy to verify the numbers with you.
Applications
Assembly stage press-fit
Positions and cushions a light press or insertion step; the rubber stoppers give a tunable, soft stop so delicate parts are not slammed at the stroke end.
Vision-inspection slide
Moves a camera or sensor into a fixed inspection pose over 40 mm; the cross-roller guide keeps the table straight so the field of view does not shift sideways.
Fixture clamping traverse
Extends a locating or clamping fixture into place on a machining fixture; adjustable stoppers let the operator dial in the exact seated position on both ends.
FAQ
How does the A-version differ from the basic HLSL20X40S, and when should I pick it?
The basic HLSL20X40S ends its stroke on rubber bumpers only, while the A in HLSL20X40SA adds adjustable rubber stoppers at both ends, letting you fine-tune the end-of-stroke position and soften light impacts without full shock absorbers. Choose the A version for light-to-moderate cycles where the stop point must be trimmed; for heavier impact energy step up to the B (both ends) or BS/BF (one side) shock-absorber versions, which are offered on this 20 mm bore.
What is the maximum working pressure, and how fast can the table move?
For this 20 mm bore the operating range is 0.15 to 0.7 MPa (22-100 psi); the maximum working pressure is 0.7 MPa regardless of bore, with 1.2 MPa as proof pressure. Use clean air filtered to 40 um and keep speed within 50 to 500 mm/s, normally set with meter-out flow control. Allowable load and moment values must be taken from the published datasheet tables and deflection curves - send us your application and we will confirm them.
