Electric motors are the workhorses of machines across many industries.

Considering the significant investment many companies put into this equipment, it’s important to minimize downtime and take extra care during maintenance. ISOMAG’s magnetic face bearing seals create a positive seal, eliminating contamination ingress and lubrication leaks.

Reliable, secure motor bearing seal operation is one of the most effective ways to extend the life of your bearings and motor equipment components while reducing maintenance expenditures and increasing uptime.

Protection during washdown

Regular high-pressure liquid cleaning puts your electric motors at risk of water intrusion, condensate buildup and, ultimately, corrosion and failure. ISOMAG’s long-term, liquid-tight seal lets you perform washdown with confidence, knowing that your bearings and bearing housing are protected.

We design our electric motor seal solutions to perform as well in preventing ingress of contaminants as they do in preventing loss of lubrication. Motor bearing protection is a critical component in controlling costs and meeting production and operational benchmarks. By preventing motor seal leaking, you can improve equipment performance while extending the time between seal and bearing maintenance and replacement events.

Performance with common lubrication types

ISOMAG magnetic bearing seals work in both grease and oil, both common to electric motor applications. Whether you need a grease seal or an oil seal, motor uptime, maintenance and performance can see positive improvements through our industry-leading seals and isolators.

Additional benefits include up to 75,000 hours of seal operation (compared with just a few months for standard lip seals), longer lubricant life span, and significantly less wear and tear on bearings and shafts.

At ISOMAG, we’ve designed our seals differently from competitors to outperform them and pass the benefits to you. Check out our comparison chart to see how ISOMAG performs against lip seals and labyrinth isolators in various conditions and lubrication systems.
