NKE Electrically Insulated Ball Bearings 6314-M-C3-SQ77

NKE Electrically Insulated Ball Bearings 6314-M-C3-SQ77

The 6314-M-C3-SQ77 is an electrically insulated ball bearing with a 70mm bore and 150mm outer diameter, designed to handle both radial and axial loads. Its outer ring features a special coating that prevents electrical currents from passing through.

With a dynamic load rating of 104kN, it can withstand heavy loads while maintaining smooth rotation up to 9500 RPM. The brass cage ensures durability and stable performance under high speeds.

The insulating coating (100-500µm thick) provides protection against electrical damage, with a breakdown voltage of 1000-3000V. This makes it ideal for electric motors or generators where stray currents are a concern.

Weighing 2.92kg, this bearing offers reliable performance in demanding industrial applications. It meets ROHS standards and comes with C3 radial clearance for versatile mounting options.
