With Plasma Technology
Electrically Insulated Bearings
Prevent bearing damage caused by stray currents
We offer a range of electrically insulated rolling bearings designed to safeguard against bearing damage caused by the passage of electrical currents that can arise from various sources in electrical machinery, leading to premature bearing failure and decreased operational reliability
Advanced plasma technology
Our electrically insulated bearings feature a robust oxide ceramic insulating layer applied directly onto the bearing ring using plasma technology.
This innovative coating boosts a guaranteed breakdown resistance of at least 1000V AC or DC, effectively preventing current from passing through the bearing elements
Enhanced operational reliability
Minimizes bearing damage from stray currents, extending lifespan and uptime.
Cost-effective solution
More economical than shaft or housing insulation for mitigating stray currents
Seamless integration
Identical dimensions ensure seamless integration into existing designs.
Durable protection
Plasma-applied ceramic coating offers long-lasting bearing protection
