Airtac TN Double Axis Double Rod Cylinder TN20X70SH
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN20X70SH is a genuine TN twin-rod (double-rod) double-acting cylinder, 20 mm bore. Two parallel rods on one plate resist bending and twisting and let the load mount without rotating. It delivers about 314.2 N of push at 0.5 MPa. A front bumper cushions the impact and adjusts the stroke over a -5 to 0 mm range.

About the Airtac TN Double Axis Double Rod Cylinder TN20X70SH
A twin-rod cylinder uses two parallel rods on one shared plate to resist bending and twisting, so the load moves without rotating. The TN20X70SH gives 314.2 N push thrust at 0.5 MPa from its 20 mm bore across a 70 mm stroke, with an external bumper that cushions impact and trims stroke by up to 5 mm.
This is a genuine AirTAC TN-series part built to enterprise standard with PT thread. A sintered NdFeB magnet is standard on every unit, with switch slots around the body. We confirm dimensions and sizing from the datasheet on request.

Specifications follow the official AirTAC TN/TR twin-rod data. Operating pressure is set by bore (0.2 MPa minimum on the 6 and 10 mm bores). The front cover and piston are short, so avoid an over-long stroke. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
Bore 20 pushes 314.2 N at 0.5 MPa, so pick the bore for your thrust need. TN is the enterprise standard with PT thread only; choose TR if you need the JIS standard with G or NPT thread or TR's higher non-rotating precision and lengthening sliding guide. Keep the stroke within the bore's table and avoid over-long strokes on the short cover, which can raise side-load. We can confirm allowable side-load from the datasheet.
Applications
Conveyor Push-Off
Push rejected parts off a conveyor lane into a reject chute. The twin rods keep the pusher face parallel so the part deflects cleanly without skewing.
Workpiece Clamp
Hold a metal bracket flat against a fixture while a drill pierces it. Anti-rotation guidance prevents the clamp from tilting under cutting load.
Pallet Stopper
Stop a pallet at a workstation on a roller conveyor. The bumper absorbs the impact and the twin rods keep the stopper face square to the pallet edge.
FAQ
What thrust does the TN20X70SH deliver?
Bore 20 pushes 314.2 N at 0.5 MPa; the pull side is lower. Confirm the exact figure for your operating pressure from the datasheet.
How does the bumper cushion work?
It is an external pad that cushions impact and adjusts the effective stroke over -5 to 0 mm. It is not an air cushion.
