Product Features
C-shaped retaining rings secure the covers, and the piston/rod assembly uses a riveted construction.
The precision-finished, hard-anodized body bore and compact double-lip seal support wear resistance and lubrication retention.
The compact body and sensor grooves simplify installation in limited space.
Dimensions for This Bore and Configuration
Dimensions are in millimeters unless a thread, angle or tolerance is stated. Letter labels follow the 126–133 printed-page drawings in the 2022 Chinese catalog. A base letter value is not automatically an overall length; use its stated stroke relationship.

P is the thread label printed in the dimensional reference drawing. The connection selected by this order code is G 1/8. PT, G and NPT threads must not be treated as interchangeable merely because they share a nominal fraction.
A, AB and the body outline are the catalog reference drawing values. The selected male rod uses the separate male-rod dimensions; do not substitute the female rod projection AB for it.

Magnetic switch condition
This code does not select a magnetic piston. A magnetic switch cannot provide piston-position sensing on a non-magnetic cylinder.
Accessory codes are listed for selection. Optional brackets, rod joints and switches are separate items unless the selected code or the stated pin note expressly identifies them. Component item numbers do not specify purchase quantities.

Stroke and Option Selection
Parameter
Details
Standard strokes for this bore/action
5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 70, 75, 80, 90, 100, 110, 120, 125, 150, 160, 175, 200, 225, 250 mm
Intermediate strokes
The catalog allows a nonstandard intermediate stroke with the outer dimensions of the next larger standard stroke; this does not extend the maximum allowable stroke.
Magnetic selection
Select the magnetic option before ordering a position switch; electrical type, cable and connector are selected separately.
Selection, Installation and Operation
Select bore from the required thrust and available pressure; then check stroke, load direction, mounting, cushioning and sensing. The general catalog load-factor references are at most 0.7 for static/slow work and at most 0.5 for 50–500 mm/s motion. They do not replace the load and guide checks for this cylinder.
Keep the piston rod and load aligned. Support lateral or eccentric loads with an appropriate guide; avoid applying bending force or tightening torque through the rod or guide.
Use clean filtered air. Prevent freezing, water, dust and corrosive substances from entering the cylinder. The cylinder is prelubricated; if lubrication is introduced, use additive-free ISO VG32 oil and continue that lubrication.
Start with the speed controller restricted, then open it gradually. Choose the circuit and flow-control direction for the action and load; a double-acting meter-out circuit is a general reference, not a guarantee of equal speed or precise stopping.
Isolate the air and electrical supplies and release trapped pressure before maintenance. Check the mounting and retained parts before repressurizing. A C-ring must be fully seated before operation.

The general 2022 selection table gives these circuit examples for this bore at a theoretical 500 mm/s reference speed. They are not included accessories, a guaranteed achieved speed, or a statement that every example screws directly into this cylinder. Match the actual port thread, action, tubing, valve capacity and operating conditions.
Weight Reference
Estimated reference weight: 1964 g. Based on the same family/bore catalog mass data and the stated configuration; it is not an AirTAC published weight for this exact variant or a measured weight. The selected mounting bracket mass is not separately listed in the cylinder weight table; this reference does not certify a packed assembly weight.
