Airtac HLS Precision Slide Cylinder HLS20X125SB
The AirTAC Airtac HLS Precision Slide Cylinder HLS20X125SB 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 HLS20X125SB
The AirTAC HLS20X125SB is a double-acting dual-rod slide-table cylinder with an integrated cross-roller linear guide. The cross-roller guide offers the highest precision and rigidity in the HLS family, and the dual rod doubles thrust while a floating joint isolates the rod from side torque. Bore 20 with a 125 mm stroke provides higher thrust and a long guided travel range.
As a genuine AirTAC part, a standard magnet is fitted for position sensing, compatible with CMSH, DMSH, and EMSH sensor switches. We verify thrust, dimensions, and load-moment data 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 delivers higher thrust than smaller HLS bores and pairs well with the 125 mm stroke for applications needing both force and extended travel. The cross-roller guide is selected for maximum rigidity and low deflection. Confirm 125 mm against the bore-20 stroke table.
The B adjuster code specifies shock absorbers on both ends, enabling smoother deceleration at higher speeds than rubber stoppers. Thread is PT. Load, moment, and kinetic-energy limits are confirmed from the published AirTAC tables and Emax values.
Applications
High-Speed Pick-and-Place
Uses the dual shock absorbers to decelerate the cross-roller table smoothly at both ends of the 125 mm stroke, supporting faster cycle rates without bounce.
Adjustable End Positioning
Provides tuned stopping force on extension and retraction for precise component placement where consistent deceleration protects delicate parts.
Test Fixture Slide
Moves a sensor or probe head across a test zone with high repeatability, absorbing end-of-stroke energy through shock absorbers for stable measurement.
FAQ
What does the B adjuster code mean and is it available on all bores?
B means shock absorbers are fitted on both ends for smoother, higher-speed stopping. B-type adjusters are not available on bore 6; they are offered on bore 8 and larger in the HLS range.
What speed range should I expect and how do I control it?
Recommended speed is 50-500 mm/s, controlled with meter-out flow controls. The shock absorbers help manage end-of-stroke energy, but operating pressure must not exceed 0.7 MPa for this bore 20 model.
