The 6317-M-C3-SQ77 is an electrically insulated ball bearing with an 85mm bore and 180mm outer diameter, designed to prevent electrical currents from passing through. Its outer ring features a special coating (SQ77) that provides insulation, with a breakdown voltage of 1000-3000V.
This bearing handles dynamic loads up to 140kN and spins smoothly at speeds up to 8000 RPM. The brass cage ensures durability, while the C3 radial clearance allows for slight misalignment or thermal expansion.
The insulation layer (100-500µm thick) offers electrical resistance of 50-200 MΩ, making it ideal for electric motors or generators. It’s also RoHS compliant for safe use in various industries.
Weighing 4.93kg, it’s a robust choice for applications where electrical insulation is critical, such as wind turbines or industrial drives.
