Import Bearing — Buy in Bulk from Supplier in China

Bearings from Aftermarkets(Quanzhou) International Co., Ltd. are precision-engineered steel components manufactured in Quanzhou, Fujian Province, designed to reduce friction and extend machinery lifespan across industrial applications. The listing indicates steel construction with ball and roller configurations available in various sizes, engineered to handle high loads and operational speeds. Ball bearings use hardened steel balls between concentric races to support radial and axial loads, while roller bearings employ cylindrical or tapered rolling elements for heavier duty cycles.

The typical material composition for bearings of this class is through-hardened chrome steel (AISI 52100 equivalent) with a Rockwell hardness of 60-65 HRC on the rolling elements, though buyers should confirm the exact alloy grade and heat treatment protocol with the supplier. Standard dimensional tolerances for industrial bearings follow ISO 492 (radial bearings) and ISO 199 (thrust bearings), with precision grades ranging from P0 (normal) to P5 (higher precision). The listing notes ISO certification, though the specific standard (ISO 9001, ISO/TS 16949) and certifying body are not stated and should be verified directly.

Applications span automotive powertrains, aerospace actuators, manufacturing spindles, and robotics joints where rotational accuracy and fatigue resistance are critical. Buyers typically source these bearings for conveyor systems, gearboxes, and electric motor assemblies. The listing mentions FOB and CIF as available Incoterms, with flexible MOQ for bulk orders, though exact quantities, lead times, and payment terms are not specified and require direct confirmation from the supplier.

Aftermarkets(Quanzhou) International Co., Ltd. operates from 4/F Gongye Building on Huancheng Road (North) in Beimen Shequ, Quanzhou, Fujian Province, postal code 362000. The supplier is classified as an imported-tier account with a harbor trust designation, indicating a verified marketplace presence without premium verification status. The response rate is recorded at 0.00 percent with zero average response hours, which suggests either a newly registered profile, inactive account, or data collection anomaly that buyers should investigate before relying on prompt communication.

The company profile does not disclose founding year, registered capital, production floor space, employee count, annual turnover, or specific manufacturing certifications beyond a general ISO reference. No named clients, export markets, or production capacity figures are provided. Buyers should request a factory profile, business licence, and ISO certificate copy before committing to volume orders. The Quanzhou location places the supplier within Fujian's machinery and auto parts manufacturing corridor, though proximity to port facilities in Xiamen or Fuzhou for export logistics is not confirmed in the available data.
