Browning R1X2-5 Split Tapered Bushing

Browning R1X2-5 Split Tapered Bushing is a Browning R1-series split-taper bushing with a 2-5/16 in bore, designed to mount a hub, pulley, or Gripbelt Sheave to a shaft using a tapered bore and a split barrel that clamps around the shaft with cap screws. This arrangement follows Browning's standard split-taper mounting method: the bushing barrel is split, the bore is tapered, and cap screws draw the assembly tight for a positive grip; external keys are used where specified by the model. The R1X2-5 variant is commonly specified for carriers that accept Browning R1-type bushings and is compatible with components that use Browning’s gripbelt/pulley hubs in power-transmission setups. Material and finish information for R1X2 bushings often appears as carbon steel (C45) with a black-oxide finish on vendor listings, though exact specifications should be confirmed from the current Browning catalog or supplier datasheet to ensure compatibility in your environment. When installing, mount the hub or pulley onto the tapered surface, align the bore with the shaft, insert the cap screws into the tapped holes, and torque to the recommended setting to achieve the intended clamping force.
