A stepped design dramatically reduces the contact between the pin and cylinder, causing instability of the pin stroke leading to increased wear. IE assemblies use a constant diameter pin which maintains its larger size through the entire piston shaft. This engineering detail increases the contact between the pin and cylinder by over 50%, increasing pin stability and an even greater displacement.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDLC COATED\u003c\/strong\u003e\u003cbr\u003eDLC (diamond-like carbon coating) is applied to the tool steel piston to increase surface hardness, reduce friction, and provide excellent wear resistance from it's self-lubricating properties.

To provide long life and withstand this torture, our tool steel cylinder is nitrided.
