To expand its offering of Ejector Sleeves, Progressive has added treatments for greaseless applications.
Black Nitride Ejector Sleeves have a precision honed lubricious surface that does not require grease in cleanroom applications, and a high hardness (66-70 HRC) that is suited for harsh conditions such as with die casting.
“When the BN Series Sleeves are combined with Progressive’s Through-Hard Ejector Pins, the dimensional specifications provide the industry’s closest combined precision fit and tolerance between pin and sleeve,” states Glenn Starkey, Progressive’s President. “Unlike PVD processes such as diamond-like coatings (DLC), black nitride penetrates the steel’s substrate and won’t chip, flake, or peel.”
