There are six main manufacturers that make equipment for the US market:
Ebonite: Makes Ebonite, Hammer, Columbia, Track
Brunswick: Makes Brunswick, Elite, Morich
Storm: Makes Storm, Roto-grip, AZO
900 Global: Makes 900 Global, Lane 1, AMF
Lanemasters: Makes Lanemasters/Legends
Visionary: Makes Visionary, Banger, previously made Insight.
Hammer, Columbia, and Track are little more than brands that Ebonite owns. Ebonite also owns Dynothane, though it's an overseas brand now.
Likewise for Roto-grip and AZO Storm owns them. They may have separate design teams and even be separate companies all owned by Storm, but they're a part of Storm.
900 Global licenses the AMF name for consumer bowling equipment from Qubica/AMF. They don't "own" AMF, it's a brand. Q/AMF makes pinsetters, lanes, house equipment,...
Lane 1, Elite, Banger, and Morich are their own companies that do their own ball designs. They aren't owned by any of the others but they do not have their own manufacturing facilities.
