Airtac HLSL Precision Slide Table Cylinder HLSL20X125SAF
The AirTAC Airtac HLSL Precision Slide Table Cylinder HLSL20X125SAF 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 HLSL20X125SAF
The HLSL20X125SAF is a symmetrical cross-roller slide table cylinder fitted with a shock absorber on the retraction side, taming deceleration as the table returns over its 125 mm stroke. The 20 mm bore works through dual rods, so the table carries twice the thrust of a single-rod cylinder of equal bore, while the integrated cross-roller guide delivers the straight, rigid, low-deflection travel this sub-family is known for. The floating joint keeps side torque off the rods entirely.
This is a genuine AirTAC part with the magnet fitted as standard; magnetic-switch slots on the body take CMSH, DMSH and EMSH switches. Exact thrust, overall dimensions and allowable load and moment values for this model come from the datasheet and the on-page specification table - ask us and we will confirm them for your application.

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
Within the HLSL line, bore 20 delivers more push than the 6 to 16 mm bores, so it is the usual pick when a transfer or light-press stroke needs extra force; the on-page table carries the verified thrust figure. Stay with the cross-roller HLSL for top precision and rigidity, or step to HLQL for anti-rust ball-bearing running, HLH for the miniature roller-ball envelope, and HLF where body height must be minimal.
Here AF means a retraction-side shock absorber on the 125 mm stroke; for stoppers on both ends choose SA, for shock absorbers both ends choose SB, and BS/BF cover the extension side or retraction side in that style. The air port is 1/8" PT, with G and NPT threads available. Allowable load and moment are published as tables and curves, so send us your load case and we will check the fit.
Applications
Vertical lift-and-lower station
The retraction-side shock absorber cushions the table as it returns, making the slide suitable for a small vertical lift where the down-stroke carries a light part.
Conveyor part push-off
Use the dual-rod thrust of the 20 mm bore to push parts off a conveyor lane, with the cross-roller guide keeping the push face square to the product flow.
Indexed fixture traverse
The precise straight travel of the cross-roller guide indexes a small fixture between positions, while the shock absorber quiets the return end of the 125 mm stroke.
FAQ
Which end of the stroke does the shock absorber sit on in HLSL20X125SAF?
The F in AF marks the retraction side: a shock absorber is fitted where the table returns to the retracted position, while the extension end retains the standard bumper. If your load arrives hard at the extended end instead, choose the AS variant, or SB for shock absorbers at both ends. This adjuster coding exists only in the HLS/HLQ families - HLH and HLF models carry no adjuster code.
Can I run HLSL20X125SAF at 1.0 MPa for extra thrust?
No. The maximum working pressure is 0.7 MPa (100 psi); 1.2 MPa is the proof pressure the cylinder survives, not an operating level. For the 20 mm bore the operating range is 0.15-0.7 MPa (22-100 psi), on air filtered to 40 um at 50-500 mm/s within -20 to 70 C. If you need more force, step up within the bore table or ask us to verify the allowable load and moment from the published datasheet for your mounting.
