Import Deep Groove Ball Bearing — Buy in Bulk from Supplier in China

The Deep Groove Ball Bearing from Jinan Zhongmei Drive Technology Co., Ltd. is engineered for industrial machinery requiring reliable radial and axial load handling. The design uses precision-ground raceways and deep grooves to support bidirectional thrust loads, with minimal friction for efficient rotation. The bearing’s sealed variants include contact or non-contact shields to block contaminants, extending service life in harsh environments.

Constructed from chromium steel (AISI 52100 or equivalent), the bearing offers typical hardness of 60-65 HRC and standard tolerance classes of P0, P6, or P5 for dimensional precision. Cage materials include pressed steel, brass, or polyamide, with polyamide cages providing quieter operation at moderate speeds. Standard lubrication uses lithium-based grease for temperatures up to 120°C, while high-temperature variants replace this with synthetic grease.

These bearings are deployed in electric motors, gearboxes, and conveyors where compact design and low maintenance are critical. Buyers in automotive, agricultural, and HVAC sectors source them for OEM applications or aftermarket replacements. Trade terms such as FOB Qingdao or CIF Shanghai are common, with packaging in single-box or palletised cartons to prevent corrosion during transit.

Jinan Zhongmei Drive Technology Co., Ltd. is based in the Flyover District of Jinan City, Shandong Province, with its registered address at Dikou Road Stephen Chunxiao 7-1-102. The company operates as an importer of mechanical components, specialising in bearings and power transmission products for industrial applications. Its profile indicates a focus on supplying OEM and aftermarket sectors with standard and custom bearing solutions.

The supplier’s current trust tier is classified as harbor, reflecting a verified business presence but with no recorded response rate or average response time in the system. This suggests buyers should confirm availability, lead times, and technical specifications directly with the company. The listing does not state certifications, production capacity, or export history, so these details require explicit confirmation.
