Bushings & Hubs
	"QD" Interchangeable Bushings:
	Sizes SH to M, and sizes N to S with a shallow keyseat, are manufactured in DUCTILE iron, a stronger material offering numerous advantages Most sizes have a set screw over the keyway to secure the key which is advantageous in vertical applications (except W & S) 100% interchangeable with licensed manufacturer’s products Available in inches & metric sizes Full, not partial split Can be mounted either way and capscrews are always accessible from the outside
Catalog Page
	"BK2" Bushings:
	Keyed on shaft and hub to reduce shock on the cap screws. Mostly used for applications with frequent stop and start or reverse needs. The taper on all BK2 Bushings is 3/4" per foot on diameter. Type 1 manufactured in cast or ductile iron, type 2 manufactured in ductile iron only. 100% interchangeable with licensed manufacturer’s products. BK2 Bushing is the most preferred style for fan blades assembly. Helps during blind Installation.
Catalog Page	Taper-Lock Bushings:
	Available in inches & millimeters Flush mounting Sizes 1008 – 5050 Peak torque loads must not exceed capacity ratings indicated.
Catalog Page
	"Short" QD Bushings:
	For applications such as conveyors or with a roller chain sprocket, when the full bore length is not needed All sizes with a shallow keyseat are in DUCTILE iron for greater strength Same features as the standard QD bushing with the exception that the total length is reduced to adapt to a QD weld-on hub Full, not partial split Sizes J, M, N, P, W (S is available in rough bore only)
Catalog Page
	"QD" Weld-on Hubs:
	For applications such as conveyor drum pulleys, rotors, plate sprockets, etc. Made of low carbon steel for its excellent welding properties Compatible with all standard QD bushings, with the exception of SD
