Clamp-style and set screw shaft collars from Grainger can be indispensable to power transmission. They can hold bearings and sprockets on shafts, situate components in motor and gearbox assemblies and serve as mechanical stops. A two-piece clamping shaft collar can easily wrap around a hard or soft shaft without marring. Set screw collars use a cup point socket set screw to lock onto a soft or predrilled shaft.
