Product Process Introduction
The grinding process is the most crucial production of wheel hub bearings.
Our ballrace grinding process for inner ring, outer ring and flange is engineered to meet the strict OEM and aftermarket performance standards.
Using high-precision CNC ballrace grinding machines, we perform twice superfinishing on every ballrace, this dual process achieving ultra-precise control over key parameters including ballrace position, curvature, roundness, parallelism, and surface roughness down to the micron level.
Introduction to Production Process
JBG controls the entire production process of wheel hub bearings, including Forging, Turning, Induction heat treatment, CNC Machning, Grinding, Assembly, Warehouse.
Especially in Forging lines, precision forging is the core of each durable wheel hub bearing. Leading other small factories in this industry, our 1,000-ton hydraulic forging presses shape raw material under extreme pressure.
This process eliminates internal defects, ensuring each forging blank meets strict dimensional tolerances before moving to subsequent machining steps. Every batch undergoes 100% inspection to guarantee consistent quality from the very start.
Assembly Process&Control
At JBG, our assembly process is fully standardized and quality-controlled to ensure precision and reliability in every wheel hub bearing:
From start to finish, every step is done with precision: we load the steel balls, set the right clearance automatically, fit the bolts, and inject grease using a controlled weighing system. Then we press the seals, assemble everything, crimp it, add the encoder and sensor, and test the ABS signal to make sure it works perfectly.
For the parts themselves, we keep tight controls: ball race parallelism under 0.005mm, roundness under 0.003mm, and roughness down to Ra 0.1mm. For different generations of hubs, we set clear clearance specs and check run-out, hole positions, and bolt alignment to make sure every unit is consistent and reliable.
Every process is designed to meet the highest industry standards, ensuring consistent performance, durability, and safety for every product we deliver.
