Product Name: Bearing Isolator Carbon Fiber Brush Ceramic Bearing Shaft Grounding Ring Wearing: No Maintenance: Free Trademark: BRS Transport Package: Carton Box Specification: shaft*excircle*7.5mm Origin: China HS Code: 8545200000 Product Description NameShaft Grounding RingMaximum Shaft Speed60m/sTemperature Limit-35oC~210oCShaft Size Range20mm~4000mmMaterialsStainless Steel, Bronze, Aluminum Alloy, Filled PTFE, PEEK, FKM rubberApplicationConstruction Equipment, Oil & Gas, Chemical, metallurgyExplainThe hydraulic seal should not only prevent the liquid from leaking from the cylinder, but also be able to withstand the high pressure, extreme temperature and lateral force of the cylinder.Features & BenefitEDM has become the main cause of motor bearing failure, and the early stage is not easy to detect, gradually motor vibration and noise become larger, and eventually lead to unexpected shutdown. The shaft grounding ring use special conductive fiber material to guide the induced shaft current through the end cover so as to avoid shaft current damage to the bearing and related equipments, effectively solve the shaft voltage problem and avoid the bearing from electrical corrosion damage.
