What is the bore of hydraulic cylinder
The bore of hydraulic cylinder is how fat the cylinder is. It’s the inner diameter of the cylinder housing which is also equal to the diameter of the piston inside of the cylinder (note the piston is not the piston rod which moves in and out of the cylinder).
The bore size determines how much force the cylinder generates. Bigger bore sizes generate more force, and also move more slowly. Smaller bore sizes are faster and weaker.
Generally the bore size is 0.5″ less than the outer diameter of the cylinder .
Bore sizes are generally standardized numbers like 2″, 2.5″, 3″, 3.5″, and 4″
A large bore hydraulic cylinder also has better stroke lengths with more extensive pressure testing.
