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.

Adjustable Motor-Mounting Bases
Increase energy efficiency in belt-driven systems while reducing wear on your components—these bases allow you to adjust your motor position to reach the proper belt tension. Choose a base that fits the NEMA frame of your motor, which is listed on the nameplate.
Bases for angular adjustment are good for applications with a 20° and greater angle between the motor and driven unit.
Bases for constant-speed applications keep your motor in a fixed position while operating equipment with a constant speed, such as fans. You can only adjust the motor position when your system is off.
Bases for variable-speed applications can move while operating to make up for vibration and varying loads. You can adjust the motor position manually while your system is running.
Bases with automatic tensioning have springs, so they maintain dynamic belt tensioning during operation to help the motor bearings, belts, and pullers last longer. They’re good for changing and challenging workloads, such as rock crushers, and excellent for reducing maintenance needed for re-tensioning.
