Electrically Insulated Single Row Cylindrical Roller Bearings NU 1018 M/C3VL0241

Electrically Insulated Single Row Cylindrical Roller Bearings NU 1018 M/C3VL0241

This electrically insulated cylindrical roller bearing measures 90mm by 140mm by 24mm and weighs 1.35kg. Its outer ring features a special coating that provides electrical resistance.

It supports dynamic loads up to 146kN and static loads of 166kN, rotating smoothly at speeds reaching 4800 RPM. The C3 radial clearance allows for thermal expansion during operation.

The machined brass cage offers durability, while the insulation protects against electrical currents up to 3000 VDC. This prevents damage from stray currents in electrically active environments.

Suitable for electric motors, generators, and industrial machinery where electrical insulation is needed. Compliant with RoHS and REACH standards for safe usage.
