Increase the Reliability of your Rotating Equipment

Inpro/Seal Bearing Isolators permanently protect rotating equipment from contamination ingress and lubrication loss, significantly increasing equipment reliability, reducing maintenance costs and unscheduled downtime.

The Importance of Bearing Protection

A leading cause of equipment downtime and lost production, bearing failure impacts equipment reliability across all industries. Over half of failed bearings are caused by lubrication loss and contaminants, such as dirt and moisture, entering the bearing housing. Because of this, maintenance professionals place an increased emphasis on bearing protection as a means of improving overall equipment reliability.

The High Cost of Contact Seals

Contact seals, such as lip seals, mechanical seals and magnetic seals, are common bearing seals that rely on mechanical contact to seal the bearing housing. Due to this, they will eventually wear at the point of contact or groove the shaft, becoming ineffective. Their short and unpredictable service life makes them inadequate to seal industrial rotating equipment. Eliminate seal failure and increase equipment reliability with a permanent sealing solution.

Permanent Bearing Protection

As the inventor of the Bearing Isolator, Inpro/Seal has delivered proven permanent bearing protection for rotating equipment, including pumps, motors, pillow blocks, gearboxes and more, for over 40 years. The Inpro/Seal Bearing Isolator’s innovative non-contacting design consists of a unitized stator and rotor that form a compound labyrinth seal with no wearing parts, ensuring permanent bearing protection against lubrication loss and contamination ingress for the lifetime of your equipment.
