Electrically Insulated Bearings
Electrically Insulated Bearings reliably prevent current discharge. Electrically Insulated Bearings provides bearings with oxide ceramic insulating layers on the bearing ring. Applied with plasma technology, the insulation has a guaranteed breakdown resistance of at least 1000V AC or DC. Two variants are available:
SQ77: Insulation on the outer ring
SQ77E: Insulation on the inner ring
Product range
SQ77 (insulated outer ring)
Cylindrical roller bearings
Design variants: NJ, NU, NUP
Dimension series: 210-230, 310-330
Cages: brass and polyamide
Radial clearance groups: C0, C3, C4
Deep groove ball bearings
Dimension series: 6212-6226; 6312-6326
Cages: brass
Radial clearance groups: C3, C4
Other types and SQ77E (insulated inner ring) upon request
Advantages
Higher operational reliability through optimum protection against electrical corrosion
More economic than, for example, insulation on housings or shafts
Interchangeable: Same key dimensions and technical properties as conventional bearings
Coating resistant to damage if correctly handled
