Company Introduction
Zhejiang J.B Auto Parts Co., Ltd. (JBG) is a technology-driven manufacturer of wheel hubs and bearings, founded in 2009. With two production bases in Ningbo (China) and Cambodia, JBG operates over 23,000 m² of facilities and serves 50+ countries including Europe, the US, and the Middle East,etc To better serve our clients across 40+ countries, we have established key overseas warehouses in Poland and the USA. JBG offers 2,500+ SKUs with an annual capacity of 1.5 million sets. The company holds multiple certifications such as IATF 16949, ISO 14001, and carbon footprint verification. With a digital factory system (MES + ERP), JBG ensures full traceability and a defect rate below 0.05%.
Product Raw Material Introduction
To avoid common manufacturing defects, instead of the shearing cutting method, JBG is using a saw cutting for blanking. This prevents riveting cracks caused by forging folds, ensuring better rigidity and fatigue durability in every unit.
For the rest of bearing components, we use high-purity GCr15 steel for inner rings to deliver excellent hardness and fatigue resistance. Outer rings are made of 65Mn or 55# steel for balanced strength and toughness, paired with precision G10-grade steel balls for stable accuracy.
By combining premium raw materials with controlled processes, JBG ensures every wheel hub bearing delivers consistent stability, durability, and safety on the road.
Introduction to Product Raw Materials
Inspection is an indispensable core procedure throughout the entire production of wheel hub units. It acts as the quality safety barrier and standard gauge for all finished products. Running through every production stage, our inspection system detects defects in a timely manner, blocks defective goods and ensures every product meets strict quality standards before delivery.
Complete Inspection Procedures
1. Raw Material Incoming Inspection
We fully inspect all raw materials including forged blanks, bearing steel, seals and fasteners. We test material composition, hardness and dimensions to eliminate raw material defects at the source.
2. Tightness Performance Test
Professional air tightness and water tightness tests are carried out to prevent oil leakage, water seepage and dust ingress during vehicle operation.
3. Durability & Environmental Test
Salt spray test, wear resistance test and fatigue life test are applied to verify product performance under harsh working environments.
