PEER Chain Offers Custom Sprockets and Keyways
Meet Ray. He is PEER Chain’s machinist and CNC operator who has decades of experience specializing in boring industrial sprockets.
In addition to traditional commercial sprocket offerings, PEER Chain & Sprockets can custom bore any size sprocket that has an existing keyway and deliver them within days of an order placement.
That sounds like an easy task, but Ray is repurposing inventory that already have existing keyways and set screws. This is a challenging machining process because of the existing keyway.
“The boring bar loves 100 percent material,” Ray said. “When boring a bigger hole in an existing sprocket, you have to drill through the existing keyway, and when you get through, the carbide is hit with a baseball bat-like crack. You don’t want that because it could undermine the bore’s dimension. The carbide starts screaming and yelling at you until it finally hits material on the other side of the keyway. Our process takes the ‘baseball bat’ out of the game.”
PEER Chain provides a wide range of finished bore and plain bore sprockets. Finished bore sprockets are machined to American National Standards Institute (ANSI) specification tolerances with one keyway aligned to the center of a sprocket tooth and with two set screws. One set screw is centered on the keyway and the other at 90 degrees.
Fact MR, the globally recognized provider of high-quality market research, predicts the global sprocket market will nearly double to $9.6 billion in 2033.
