Bearing Seal Solutions

All bearing seals are not the same — not by a longshot. Only ISOMAG delivers a long-term, liquid-tight seal without heat generation, equipment degradation, lubricant egress or contaminant ingress. For more than 25 years, we’ve continued to bring true innovation to the industry because we simply don’t accept the limitations of other bearing seals.

Wear and tear is preventable.

Lip seals use the equipment’s shaft as the primary sealing surface, causing wear to your host equipment. The average lip seal life cycle is 3-6 months, leading to frequent downtime and less MTBR (maintenance time between repair). ISOMAG’s O-ring driven sealing face rotates with the shaft — avoiding metal-to-metal contact, preserving shaft integrity and extending bearing life up to 75,000 hours.

Lubricant leakage is not a “given.”

Labyrinth isolators create a restrictive, close-clearance path that’s inherently vulnerable to contamination ingress and lubrication egress, leading to frequent and expensive oil changes and sacrificing the reliability of your equipment. ISOMAG’s precision-controlled, deep-channel oil groove retains and circulates bearing lubrication, preventing bearing lubrication leaks. Our positive seals are long-term and liquid-tight, whether it’s liquid lube, oil mist or grease.

We’re trusted across lubrication systems, operating conditions and equipment applications:
