Bearing Isolator

Contamination ingress and lubrication loss are the leading causes of bearing failure. Permanently protect against these issues with the Inpro/Seal Bearing Isolator, a non-contacting labyrinth seal designed to last the lifetime of your equipment.
Smart CDR shaft grounding solution

Shaft Grounding

VFD-driven motors create harmful shaft currents that discharge through equipment bearings, leading to bearing failure. Protect your equipment with Inpro/Seal Smart Shaft Grounding™. Proprietary conductive filaments provide a low impedance path to ground, while an innovative sleeve promotes premium performance.

Case Study

Current Diverter Ring (CDR) Protects Energy-Efficient HVAC Equipment

A leading plastic injection company planned to install VFDs on their chiller pumps to increase energy efficiency and reduce operation costs. To safeguard their investment, they specified the inclusion of a shaft grounding solution in the installation. Inpro/Seal was able to custom engineer a split-design CDR for each piece of equipment, accommodating shaft diameter variations on the customer’s motors.
