Airtac HLQ Dual-Axis Precision Slide Table Cylinder HLQ20X40SA
The AirTAC Airtac HLQ Dual-Axis Precision Slide Table Cylinder HLQ20X40SA is a genuine HLQ slide-table cylinder, 20 mm bore: a double-acting dual-rod air cylinder integrated with a ball-bearing 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 HLQ Dual-Axis Precision Slide Table Cylinder HLQ20X40SA
The HLQ20X40SA is a double-acting dual-rod slide-table cylinder that integrates an air cylinder with a ball-bearing linear guide, so the moving table travels straight with minimal deflection. The 20mm bore and 40mm stroke deliver moderate thrust over a compact travel range, while the dual rod doubles the output force and a floating joint protects the rods from side torque. The HLQ ball-bearing guide is anti-rust and dust-proof, well suited to clean or mildly corrosive environments where cross-roller rigs would be overkill.
This is a genuine AirTAC part with a standard sintered NdFeB magnet for position sensing; compatible sensor switches are the CMSH, DMSH, and EMSH series, which seat in the magnetic-switch slots on the body. We confirm exact thrust, overall dimensions, and load-moment ratings from the AirTAC datasheet or the 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 sits in the mid-range of the HLQ family; a larger bore gives more push for heavier workpieces but consumes more air, so pick the smallest bore that meets your thrust need. Choose HLQ ball-bearing when anti-rust and dust-proof operation matter; choose HLS cross-roller for maximum rigidity, HLH for multi-port precision assembly, or HLF for reduced height. This model carries the A adjuster (adjustable rubber stopper at both ends) for controlled end-of-stroke positioning; shock-absorber (B) options exist on other variants but are not on bore 6. Thread is PT (tapered). We route allowable load and moment sizing to the published tables and deflection curves, confirming values from the datasheet before you order.
Applications
Pick-and-Place Head
Mounts a small vacuum gripper on the table for precise pick-and-place of electronic components on a PCB assembly line.
Parts Transfer Stopper
Extends across a conveyor lane to stop small parts at a defined position for inspection or downstream handling.
Gripper Traverse Stage
Shuttles a parallel gripper between two fixture stations on a light-assembly machine with low-deflection guided travel.
FAQ
What does the A in HLQ20X40SA indicate?
A means the cylinder has an adjustable rubber stopper at both ends, giving fine control over end-of-stroke positioning without adding a separate shock absorber. If you need shock absorption instead, look for B-type variants.
What is the maximum operating pressure for this bore?
Maximum working pressure is 0.7 MPa (100 psi). For bore 20 the operating range is 0.15-0.7 MPa (22-100 psi). Use meter-out speed control to keep travel at or below 500 mm/s.
