About Shaft Collars
Shaft collars are useful for holding and positioning components on a shaft. They can also serve as mechanical stops and stroke limiters.

Clamping Two-Piece Shaft Collars
These metal collars are stronger than plastic shaft collars. The two-piece design allows you to install them anywhere on a shaft without removing components or having access to the ends of the shaft. Collars clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screws to secure.
Black-oxide steel collars have some corrosion resistance. Zinc-plated steel and chrome-plated steel collars have moderate corrosion resistance with a bright finish. 303 stainless steel collars have excellent corrosion resistance.

Shaft Grounding Rings
Prevent motor downtime by protecting bearings from stray currents generated by variable frequency drives. These grounding rings create a path for stray currents, so they won't damage bearing surfaces. Use them on AC motors.
One-piece rings slide on from the end of the shaft. Two-piece rings simplify installation when motors are connected to equipment.
Use epoxies to install rings without having to drill or tap into motor frames.
Apply shaft coatings to motor shafts before installing the rings to improve the conductivity of the steel shaft surface that touches the grounding ring.
