Industrial gearboxes are tough components that operate at high speeds and often under extreme temperatures and pressure. ISOMAG’s magnetic face bearing seals protect and extend the life of gearboxes by creating a positive seal that eliminates contamination ingress and prevents the lubrication problems that account for a large percentage of gearbox failures.

Going beyond lip seals

The standard seal for gearboxes is currently the lip seal, which uses the host equipment shaft as the primary sealing surface and leads directly to wear and tear. ISOMAG bearing seals rotate with the shaft to avoid metal-to-metal contact — providing a true long-term solution and significant upgrade. Learn more about how our products compare to lip seals.

Performance with common lubrication types

ISOMAG magnetic bearing seals work in both grease and oil, both common to electric motor applications. Check out our comparison chart to see how ISOMAG performs against lip seals and labyrinth isolators in various conditions and lubrication systems.

At work every day in the real world

ISOMAG helps companies across many industries protect the integrity and performance of their gearboxes. Read about how ISOMAG helped eliminate the problems caused by leaking oil from cooling tower gearbox input shaft seals.
