Three-Screw Slip Ring Centering Hub
This stator hub holds a capsule slip ring on the axis of a pan platform, rotating sign or antenna turntable, so the wiring doesn't wind up as it spins. Slip ring sizes vary by maker, so instead of one fixed bore it has a 27 mm through-bore with three radial M3 screws in captive-nut slots at 120°. Those screws centre and lock any body from about 10 to 25 mm diameter. The base is 70 x 70 mm with four radial M3 slots for any platform pattern, plus two zip-tie bridges to strain-relieve the stator leads.
