6317m.C3.J20C Insulated Bearings
The 6317m.C3.J20C is a deep groove ball bearing with a C3 radial internal clearance and a J20C suffix, indicating a specific insulation treatment for electrical resistance. This model is engineered for heavy radial and moderate axial loads, with the C3 clearance accommodating thermal expansion in high-temperature environments. The insulated design mitigates electrical pitting, a common issue in variable frequency drive motors.
The bearing is typically manufactured from high-carbon chromium steel, heat-treated to achieve a hardness of 58-65 HRC, standard for this category. The J20C suffix denotes an insulated coating on the outer ring, usually a ceramic or oxide layer with a thickness of 50-150 micrometers, providing a dielectric barrier. The bearing’s deep groove geometry allows for high-speed operation, with grease lubrication standard for sealed variants.
Industries such as manufacturing, automotive, and renewable energy use this bearing in motor and generator assemblies, where stray currents can reduce component lifespan. The supplier, based in Bachalu Industrial Park, Linqing, Shandong, offers the product with FOB or CIF shipping terms, but MOQ, certifications, and lead times are not stated and should be confirmed directly. The bearing’s precision dimensions ensure compatibility with a range of machinery.

Sourcing 6317m.C3.J20C Insulated Bearings from Linqing Nine Star Bearing Science & Technology Co., Ltd. - China Import Guide
Before placing an order, confirm the bearing’s dielectric strength and insulation rating to ensure it meets your application’s voltage requirements. Request test reports for the insulation coating’s integrity, as this is critical for preventing electrical damage in motor assemblies. Verify whether the coating is applied to the inner or outer ring, as this affects installation compatibility.
Clarify the Incoterms (FOB or CIF) and packaging specifications, as these impact shipping costs and handling procedures. For bulk purchases, negotiate MOQ and lead times directly with the supplier, as these details are not provided in the listing. Payment terms such as L/C or T/T should also be discussed, along with export documentation requirements.
Upon receipt, inspect the bearing for dimensional accuracy, surface finish, and coating uniformity. Request a certificate of conformity to ISO 15:2017 or other relevant standards. For high-value applications, consider a third-party inspection to validate the insulation coating’s thickness and dielectric properties, ensuring it meets your technical specifications.
