How to Measure an Existing Welded Cylinder
- Bore diameter: Measure inside diameter of the barrel (or use rod diameter + double wall thickness)
- Rod diameter: Measure outside diameter of the piston rod with calipers
- Stroke length: Fully retract cylinder, mark rod. Fully extend, measure distance between marks
- Retracted length: Distance between mounting pin centers when fully retracted
- Extended length: Retracted length + stroke
- Port size and type: Check thread type (NPT, SAE, BSPP) and nominal size
- Mounting type: Cross tube, clevis, trunnion, flange
