End clearance on piston rings depends on ring design, material andapplication. The following end clearances are provided as a standard for hydraulic cylinder applications. When using iron piston rings, it is crucial to use the correct groove design for proper performance of the cylinder. Please use the following guidelines when cutting an iron piston ring groove.
GROOVE WIDTH: To permit the ring to slide freely into the groove, the groove must be at least 0.001” wider than the maximum piston ring width with a tolerance of +0.003”/-0.000”.
GROOVE DEPTH: Grooves must be at least 0.015” deeper than the maximum radial wall thickness of the piston ring with a tolerance of +0.003”/-0.000”. This is to avoid any possibility of the ring bottoming in the groove when the ring is compressed to its working diameter.
RADIAL CLEARANCE: The radial clearance between the cylinder bore and piston should be less than 1/3 of the radial wall thickness of the piston ring to ensure sealing effectiveness.

Style ST-XL wipers are molded from premium urethane and are direct replacements for Style “ST” or “D” wipers. The outside diameter of the ring has a crush lip providing extra interference in the groove. A bead on the shoulder stops contaminates from entering through the groove. The inside diameter is ribbed to prevent pressure traps between the wiper and rod seal.
