Import Bearings — Buy in wholesale FOB from Supplier in China

Jma Bearing Zhejiang Limited Company, located at 509 Shuguang Road, Shaoxing, Zhejiang Province, China, manufactures ball and roller bearings from chrome steel (GCr15 / AISI 52100) and stainless steel 440C for industrial machinery, automotive systems, and power transmission equipment. The product range includes deep groove and angular contact configurations, engineered to ISO/ABEC standards with emphasis on low friction operation and high load capacity. Shaoxing sits within China's eastern manufacturing belt, providing established supply chain networks for steel sourcing, precision machining, and export logistics infrastructure.

Chrome steel GCr15, chemically equivalent to AISI 52100, provides the foundational material for standard duty bearings with typical carbon content 0.95-1.05% and chromium 1.30-1.65%, achieving 60-67 HRC surface hardness after martensitic heat treatment. Angular contact bearings from this supplier suit paired mounting arrangements where combined radial and axial loads require controlled preload or endplay adjustment, typical in machine tool spindles and gearbox shafts. Stainless steel 440C variants trade some load capacity for corrosion resistance in food processing, marine, or chemically exposed environments where standard bearing steels would suffer pitting or rust staining.

The intended buyer base spans automotive OEMs, maintenance repair operations, industrial equipment manufacturers, and aftermarket distributors requiring standardised dimensional interchangeability. Deep groove bearings handle predominantly radial loads with moderate axial capacity in either direction, while angular contact designs manage higher thrust components through optimised contact angle, typically 15°, 25°, or 40° depending on thrust-to-radial load ratio. Buyers should confirm with Jma Bearing Zhejiang Limited Company the specific contact angle, cage design, and seal or shield configuration for their application, as these parameters significantly affect speed capability, contamination resistance, and maintenance intervals.

Jma Bearing Zhejiang Limited Company maintains its registered address at 509 Shuguang Road, Shaoxing 312081, Zhejiang Province, China, placing it within one of China's concentrated precision manufacturing regions with established bearing industry ecosystems. The supplier holds an Imported tier designation alongside Harbor trust status, indicating cross-border trade orientation within the platform's classification system. No response rate data or average response hours are recorded, so buyers should initiate direct contact to gauge quotation turnaround and technical support availability.

The company's profile emphasises bearings for industrial and automotive applications with ISO/ABEC standard compliance, though no specific factory size, employee count, annual revenue, named clients, or certification body accreditation details appear in the available data. Buyers evaluating this supplier for volume contracts should request quality management system certificates (ISO 9001, IATF 16949 for automotive), production capacity figures, and evidence of in-process quality controls such as roundness testing, vibration analysis, or dimensional statistical process control records.
