Electrically Insulated Single Row Cylindrical Roller Bearings NU 219 ECM/C3VL0241

Electrically Insulated Single Row Cylindrical Roller Bearings NU 219 ECM/C3VL0241

This electrically insulated cylindrical roller bearing has a compact build, measuring 95mm in bore, 170mm outside, and 32mm wide. It’s made with a robust design to handle substantial radial loads.

The bearing supports dynamic loads up to 530 kN and static loads up to 540 kN, operating smoothly at speeds up to 3400 RPM. Its C3 internal clearance accommodates thermal expansion during use.

A key feature is the outer ring’s insulating coating, which prevents electrical damage by resisting voltages from 1000 to 3000 VDC. The machined brass cage adds durability and helps maintain performance.

Suitable for electric motors or generators where stray currents are a concern, it’s also RoHS and REACH compliant. Weighing 2.84kg, it offers reliable protection in demanding industrial settings.
