Daikin-McQuay 048417210 SF Series QD Split Taper Bushing 1-11/16 Bore

The Daikin-McQuay 048417210 is an OEM SF Series Quick Detachable (QD) Split Taper Bushing with a 1-11/16" (1.6875") finished bore. Designed for use in commercial HVAC equipment manufactured by Daikin Applied and McQuay International, this bushing secures sheaves, pulleys, and sprockets to drive shafts in fan, blower, and pump assemblies.

The split taper design features a tapered outer barrel that mates precisely with the tapered bore of the driven component hub. When draw bolts are tightened, the bushing compresses concentrically around the shaft, creating a tight, vibration-resistant mechanical lock without relying solely on keyways. This construction simplifies both installation and removal during routine HVAC system maintenance.
