Import Bearing — Buy in Bulk from Supplier in China

This listing offers HRB or KOYO ball bearings, sourced directly from stock in China. The bearings measure 10 cm x 8 cm x 2 cm (3.94 in x 3.15 in x 0.79 in) and are engineered to match Japanese bearing performance standards, with testing confirming compatibility with original engine specifications. HRB, the largest bearing manufacturer in China, produces these units to near-Japanese quality benchmarks, ensuring reliable operation in demanding applications.

The ball bearings are designed for radial load support and friction reduction, typical of deep-groove designs used in automotive, industrial machinery, and power transmission systems. Standard materials for such bearings include chrome steel (GCr15) or stainless steel (AISI 440C), with typical precision grades ranging from P0 to P6 for dimensional and running accuracy. Surface finish is usually Ra 0.2-0.8 µm, and standard cage materials are pressed steel or polyamide, depending on the series.

These bearings are commonly used in electric motors, gearboxes, and conveyor systems where consistent performance under moderate to high speeds is required. Buyers typically source them in bulk for maintenance or OEM assembly, with packaging often in standard industrial cartons or palletized for export. Lead times and MOQs vary by stock availability, and buyers should confirm compatibility with their specific machinery before ordering.

Top Real Business is based in Pingxiang, Jiangxi Province, China, with its registered address at No 5 Binhe Community, Yangmeitang Road. The supplier operates as an importer-tier business with a harbor trust tier, indicating a focus on cross-border trade but with no verified response history on the platform.

The company specializes in selling HRB and KOYO ball bearings, leveraging HRB’s position as China’s largest bearing manufacturer. Their inventory depends on stock conditions, and they explicitly state they do not supply poor-quality bearings. However, buyers should note the lack of response metrics and confirm stock availability and specifications directly.
