The electric insulation bearing supplied by Shandong Zhisheng Bearing Co., Ltd. incorporates oxide ceramic (Al2O3) rolling elements paired with chrome steel (GCr15) rings. It is engineered to block the passage of stray electrical currents that can arise in variable frequency drive systems, large electric motors and generators. The design conforms to IEC 60034-5 and DIN 62000 insulation standards, providing reliable protection in demanding applications. Available configurations include deep-groove, angular-contact and cylindrical types.
Oxide ceramic rolling elements deliver high hardness and wear resistance while maintaining excellent electrical resistivity, whereas the chrome steel rings give the bearing robust load-carrying capacity. In the bearing industry typical dynamic load ratings for similar ceramic-steel hybrids reach up to 200 kN and permissible speeds can exceed 15 000 rpm. Standard operating temperatures range from -40 °C to +150 °C, and insulation resistance is typically specified at a minimum of 10 MΩ measured at 500 V. These typical parameters help OEMs match the bearing to motor designs that require both mechanical strength and electrical isolation.
The bearings are sourced by industrial bearing exporters for OEM assembly and routine maintenance of VFD-driven equipment worldwide. Buyers typically place bulk orders and should confirm the exact bore, outer diameter and width required for their machinery before finalising the purchase. Trade terms, packaging options and lead-time estimates are negotiated directly with Shandong Zhisheng Bearing Co., Ltd. and can be aligned with standard Incoterms such as FOB or CIF as the buyer prefers.

Shandong Zhisheng Bearing Co., Ltd. is located in Linqing City, Shandong Province, China, postal code 25225. The company holds a harbor-level trust tier on the platform, indicating a verified business registration, but its response rate is currently recorded as 0 % with no average response time logged. The profile lists the supplier’s address but does not disclose production capacity, certifications or client references. Prospective buyers should therefore request detailed company documentation to confirm manufacturing capabilities.
The listing identifies the firm as an electric insulation bearing manufacturer, focusing on ceramic-steel hybrid bearings for motor and generator applications. No specific information is provided regarding quality management systems or export experience, so buyers are advised to ask for any ISO certifications or past export records. Communication channels are limited, making it prudent to establish clear written agreements before transaction. The supplier’s presence in a major industrial region of China suggests access to local logistics networks.
Electric insulation bearings are engineered to prevent electrical current passage through rolling elements, protecting machinery in variable frequency drive (VFD) environments, large electric motors, and generators. Featuring oxide ceramic or silicon nitride rolling elements bonded to chrome steel rings, these bearings meet IEC and DIN standards and are available in deep groove, angular contact, and cylindrical configurations. Widely sourced from industrial bearing exporters for OEM assembly and maintenance applications worldwide.

Before placing an order, buyers should request the supplier’s material traceability sheet confirming the Al2O3 ceramic composition and GCr15 steel ring alloy. Insulation test reports demonstrating compliance with IEC 60034-5 and the measured resistance at 500 V are essential for confirming electrical safety. It is also advisable to obtain a dimensional drawing that lists bore, outer diameter and width tolerances to ensure fit-for-purpose selection.
Typical logistics for bearings from Shandong Zhisheng Bearing Co., Ltd. involve shipment from ports such as Qingdao or Tianjin under FOB terms, though buyers may negotiate CIF or DAP as required. Lead-time estimates are usually quoted between 30 and 45 days after order confirmation, subject to production scheduling and customs clearance. Payment is commonly arranged via irrevocable T/T letters of credit, and buyers should verify the exact Incoterm and payment schedule before contract signing.
Importers should arrange a third-party inspection covering visual appearance, dimensional conformity
