Insulation Cylindrical Roller Bearing
The Insulation Cylindrical Roller Bearing supplied by Qingdao Rensheng Huida Trading Co., Ltd. combines chrome steel GCr15 with a ceramic or PEEK insulating oxide coating on the outer race. It is intended for high‑voltage motor and generator applications where electrical isolation is critical to prevent bearing damage. The supplier notes compliance with international ISO standards and production from its Qingdao, China facility. Custom roller dimensions can be tailored to fit specific machinery requirements.
The ceramic and PEEK coatings act as dielectric layers while the GCr15 steel core supplies the high hardness and fatigue strength typical of roller bearings. In the sector, such insulated roller bearings are classified as Class II insulation and are widely used in electric‑vehicle traction motors and railway traction systems. Typical designs operate at speeds up to 12 000 rpm and maintain load capacity comparable to uncoated rollers. Alternative coatings may be selected based on temperature resistance and chemical exposure.
Key customers include manufacturers of large AC motors, railway traction equipment and power‑generation units that demand reliable isolation of rotating shafts. The listing mentions flexible MOQ, FOB or CIF shipping options and payment by L/C or T/T, supporting both large‑scale and smaller orders. Buyers should verify packaging style, as the bearings are often shipped in wooden crates with anti‑corrosion film. Trade conditions are negotiable prior to order confirmation.

Sourcing Insulation Cylindrical Roller Bearing from Qingdao Rensheng Huida Trading Co., Ltd. - China Import Guide
Prior to ordering, confirm the exact GCr15 steel grade, the chosen insulation coating type and the dimensional tolerances required for your application. Ask the supplier to supply the mill test report and the ISO certificate referenced in the listing to ensure material and coating quality meet your standards. Early verification reduces the risk of receiving non‑conforming components.
Discuss the preferred Incoterm - FOB or CIF - and align it with your logistics strategy. Confirm the payment method, whether L/C or T/T, and request an estimated production lead time, as the listing does not provide a specific schedule. Clear agreement on these terms helps avoid delays in the import process.
Plan for a pre‑shipment inspection by a recognized third‑party agency to validate coating thickness, hardness and dimensional accuracy. Ensure that the wooden crates are sealed and that the anti‑corrosion film is intact before loading. Retain all inspection reports and certificates for customs clearance and future quality assurance activities.
