Wall thickness .150"- number indicates first two decimal places Series/Material 300M Aerospace steel, straight wall Lock type C or S- C Chamfer end S Sharp end Cut-a-way of a Tapered Wrist Pin TAPERED PINS Tapered wall pins are designed for the highest strength to weight ratio possible while the length of the taper has been optimized for the piston pin boss span. JE tapered wall pins are hand lapped to the finest I.D. finish available in the industry. DLC (DIAMOND LIKE CARBON) DLC (Diamond Like Carbon) is an extremely hard, wear resistant coating with a very low friction coefficient of 0.1-0.2. Excellent adhesion to steel and Titanium is achieved via a plasma assisted chemical vapor deposition (PACVD) process. During this process sp2 and sp3 carbon atoms form diamond shaped bonds with the base material thereby earning the name Diamond Like Carbon. The wear resistance and non-stick performance of DLC make it an excellent addition to wrist pins for the prevention of pin bore galling.
