C_o : Machined or rolled at the discretion of the manufacturer.

C_i : Can be a radius or a chamfer in accordance with ISO 13715.

Features
•Low static and dynamic friction coefficient.
•High resistance to both cavitation and flow erosion damage
of the polymer bearing surface by the lubricant.
•Suitable for sliding, oscillating, reciprocating and rotating applications.
•Also suitable for use with non-lubricating fluids and in light duty unlubricated applications.
•Excellent wear resistance.
•Lead-free and therefore ELV (End of Life of Vehicle) and RoHS compliant.
