HC-5625-12 has a 6.5 in OD and is made to fit a 5 in bore cylinder.

Head cap size is determined based on the bending stress.

A static seal or o-ring is used in between the head cap and barrel (except welded construction).

The main function of the head cap is to enclose the pressure chamber at one end. The cap is connected to the cylinder body by means of welding, threading, bolts, or tie rod.

Used interchangeably for piston or rod sealing, these u-seals employ the same tough urethane material found in our, Heavy Duty Rod and Piston U-Seals.

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.

ALUM-7000 has a 7 in diameter. The material is 6061 Aluminum T6

6061 Aluminum T6 is suitable for machining pistons and head glands.

The T6 refers to the temper or degree of hardness. T6 has been solution heat treated and artificially aged to provide the maximum yield strength for a 6061 aluminum alloy.

• Heat treated and aged for increased strength
• Easily formed
• Weldable
• Corrosion resistant

Full mill lengths will be cut to lengths between 12 ft and 19 ft long. Packages longer than 44 inches may have additional freight charges.

AN wipers are ideal for light duty and pneumatic applications. Its main purpose is to prevent dirt and contaminants from entering the hydraulic or pneumatic systems. Suffix “SH” designates slotted heel design, “V” designates fluorocarbon material, and “B” designates carboxilated nitrile material.
