Pancake II cylinders come in standard, non-rotating, force-multiplying, and 3-position models with eight bore sizes from 1/2 to 4 in. High-strength, self lubricating composite cylinder barrels and oversized, non-metallic piston rod bearings ensure high load bearing capacity, reduced friction, and zero slip stick.
