CHIPRO: R&D innovation serves as the company’s core competitive advantage.

CHIPRO Chichuang has always understood that research and development innovation is never achieved overnight; it typically requires long-term accumulation. Therefore, from its inception, the company established a technical R&D team. After more than a decade of steady progress, it has gradually accomplished breakthroughs from zero to one, ultimately forming today’s nascent yet sizable Hangzhou Chichuang Technology Center. Founded in 2012 and located at No. 3 Taiji Road, Linping Economic and Technological Development Zone, Hangzhou, the center currently employs over 20 technical engineers. It comprises several major functional modules—design, simulation, verification, measurement, prototyping, validation, testing, experimentation, disassembly, analysis, inspection, and conclusion—and is committed to building a one-stop service platform for bearings. Introduction to Functional Areas and Instrumentation: Testing: Primarily used for evaluating bearing dimensions, clearance, noise levels, and specialized performance characteristics. Currently available instruments include internal diameter gauges, external diameter gauges, end height gauges, radial clearance gauges, axial clearance gauges, bearing vibration meters, torque testers, tensile/compressive force testers, cleanliness analyzers, and volatiles detection devices, among others. Precision Measurement: Mainly employed to assess bearing geometry, surface roughness, elemental composition, material properties, and hardness. Existing equipment includes electronic balances, stereo microscopes, Rockwell hardness testers, Vickers hardness testers, metallographic microscopes, roughness profilers, roundness testers, and material analysis spectrometers, among others. Experiments: Used primarily for performance testing, lubrication studies, torque evaluations, operating condition tests, and accelerated life‑testing. Current facilities comprise salt spray chambers, high/low temperature test chambers, dust‑proof test chambers, small bearing life‑testing machines (for fatigue, temperature rise, lubrication life, and high‑temperature tests), high‑speed bearing life‑testing machines (oil‑lubricated, mainly for fatigue, high‑speed, and temperature‑rise tests on high‑speed bearings used in new energy vehicle gearboxes), high‑speed bearing life‑testing machines capable of simulating environmental temperatures (primarily for high‑speed tests on new energy vehicles and high‑speed permanent magnet motors, including temperature rise, lubrication life, or maximum rotational speed tests), and heavy‑load bearing life‑testing machines (used for heavy‑load fatigue tests on new energy vehicles, static impact tests, and heavy‑load fatigue tests on truck ball bearings, among others). CHIPRO With R&D at its core and services as its foundation, Chichuang is forging a fast track for the development of its own bearing industry services. To further shorten the new product development cycle, Chichuang will also establish its own prototype manufacturing facility, creating a closed-loop industrial service system—from operational condition surveys and design R&D, through production and manufacturing, to life‑testing, failure analysis, and iterative redesign. Humanity thrives endlessly, and the Earth keeps turning in an eternal cycle. Our mission is to make the rotating world more reliable by innovating precisely in material structures, manufacturing processes, and component configurations. True innovation does not mean surpassing competitors—it means transcending limits.

Chichuang has always recognized that R&D innovation is never a one‑step achievement; it typically requires years of sustained effort. From its inception, the company established an R&D team and, over more than a decade of steady development, gradually achieved breakthroughs from scratch, culminating in the establishment of the Hangzhou Chichuang Technology Center, which has now reached a considerable scale. The Technology Center was established in 2012 and is located at No. 3 Taiji Road, Linping District Economic and Technological Development Zone, Hangzhou. It currently employs more than 20 technical engineers. The center comprises several key modules—design, simulation, verification, measurement, prototyping, validation, testing, experimentation, disassembly, analysis, inspection, and reporting—and is committed to building a one-stop service platform for bearings.

Introduction to Partition Functions and Instrumentation:

Testing: Primarily used for assessing bearing dimensions, clearance, noise levels, and special performance characteristics.

Currently available instruments include: bore gauges, outside micrometers, height gauges, radial clearance gauges, axial clearance gauges, bearing vibration meters, torque testers, tensile‑and‑compressive force testers, cleanliness analyzers, and volatiles‑testing equipment, among others.

Precision Measurement: Primarily used for assessing bearing geometry, surface roughness, elemental composition, material properties, and hardness. Current equipment includes electronic balances, stereo microscopes, Rockwell hardness testers, Vickers hardness testers, metallographic microscopes, surface roughness profilers, roundness testers, and material‑analysis spectrometers, among others.

Testing: Primarily used for bearing performance testing, lubrication testing, torque testing, operating-condition testing, and life‑enhancement testing, among others.

Currently, we are equipped with a salt spray testing machine, high- and low-temperature chambers, a dust‑proof test chamber, and several specialized bearing life‑testing machines: a compact bearing life tester (primarily used for bearing fatigue, temperature‑rise, lubrication‑life, and high‑temperature tests), a high‑speed bearing life tester (oil‑lubricated; mainly employed for fatigue, high‑speed, and temperature‑rise testing of high‑speed bearings in new‑energy vehicle gearboxes), another high‑speed bearing life tester capable of simulating ambient temperatures (designed for high‑speed, temperature‑rise, lubrication‑life, and ultimate‑speed tests on high‑speed bearings for new‑energy vehicles and high‑speed permanent‑magnet motors), as well as a heavy‑load bearing life tester (used for heavy‑load fatigue and static impact testing in new‑energy vehicles, and for heavy‑load fatigue testing of truck ball bearings, among other applications).

With R&D at its core and services as its backbone, Chichuang is forging a fast track for the development of bearing‑industry services. To further shorten the new‑product development cycle, Chichuang will also establish its own pilot‑production facility, thereby closing the loop of bearing‑industry services—from operating‑condition analysis and design R&D to manufacturing, life‑testing, failure analysis, and iterative design refinement.

Humanity endures, and the Earth turns in an endless cycle. Our mission is to harness innovation—through meticulous design of material structures, manufacturing processes, and system configurations—to make our spinning world more reliable. True innovation does not mean outpacing competitors; it means pushing beyond limits.
