Gear Coupling

Full gear type BFG Boson flexible gear coupling consists of two identical toothed hub, two identical, flanged sleeves with internal teeth, a set of flanged bolts, nuts and lock washers, and lube plug.
The basic characteristics of BOSON curved tooth flexible gear couplings are distinguished by their mechanical strength and flexibility, which accomodates angular offset or combine angular offset misalignment within allowable ratings but also permits axial float or thermal expansion of connected shafts.
