What Li Jianfeng specially advised, Zhang Fugui naturally couldn't forget.

Soon, Zhang Fugui took out three complete test reports from his bag and handed them to Bu Defan, Hassan and Li Jianfeng respectively.

Although they are not professional technicians, they can still understand the general reports when they deal with suppliers every day.

"Lee, this data on strength, stiffness and bearing drag torque, sure there is no problem?"

Bu Defan looked at Nanshan's test report, and then looked at the SKF test report prepared by himself next to him, and saw a clear difference.

Diameter, width, PCD and hole position, offset, center hole and other dimensions related data, a little difference is good or bad, he is not necessarily clear.

But strength and stiffness, that is definitely the higher the better.

The Santana wheel bearing made by Nanshan in front of him has a strength data that is more than 30% higher than that of SKF.

Because bearings are subjected to very large radial and axial loads, strength is critical.

As for the stiffness, it is also significantly higher than that of SKF.

If the stiffness of the bearing is very poor, it will cause a large deformation of the flange surface connecting the bearing and the brake disc when the bearing is subjected to lateral force, which will lead to problems such as eccentric wear of the friction plate.

The difference in bearing drag torque is even more obvious.

The drag torque of the bearing is the resistance of the bearing when it rotates, and its magnitude affects the fuel consumption.

According to Bu Defan's calculations, if the data provided by Nanshan is true, then after using their wheel bearings, Santana's fuel consumption may be reduced by 0.1L/100KM.

It may seem inconspicuous, but from a design point of view, it is already a very exaggerated figure.

"Mr. Bu Defan, our wheel bearings, presumably the Modu Volkswagen has also been obtained, and even personnel have been arranged to test it."

"Whether the report in my hand is true or false, even if you have no way to judge today, it will take ten and a half months at most to confirm it."

"In this case, if I show you a false report, wouldn't I dig my own grave?"

Zhang Fugui's face was full of confidence.

There is absolutely no moisture in this report.

Regardless of whether it is the public of the magic capital or other institutions, no matter how much it is tested, it is not afraid.

"The bearing life calculated in your test report is more than 200,000 kilometers, which is why you dare to promise a lifetime warranty?"

After listening to Zhang Fugui's words, Bu Defan did not bother with the data just now, but shifted his attention to other places.

Ideally, bearings are maintenance-free throughout the life of the vehicle, so they must last longer than the life of the vehicle.

However, at this time in 2001, due to various reasons such as road conditions and parts quality, some wheel bearings will begin to have problems after 8~10 years.

Even in 2023, the wheel bearings of some manufacturers will not be maintenance-free for life.

"That's right, as we all know, the design of the wheel bearing seals is very critical."

"Good seal ring design and poor design can make the bearing life several times worse, and the failure rate can be much worse."

"Our Nanshan wheel bearings have adopted a unique design scheme, which is a patented technology belonging to our Nanshan, and neither SKF nor NTN can compare to us in this aspect."

As soon as Zhang Fugui said this, Bu Defan and Li Jianfeng glanced at each other.

Obviously, this situation was a bit of a surprise to them.

"Zhangbu, take the liberty of asking, as far as I know, you haven't made bearings before, how can you suddenly make such an excellent hub bearing?"

Li Jianfeng's question is shared by many people.

However, Zhang Fugui had discussed this topic with Cao Yang before, so now that he was questioned, he was not flustered.

"Li Gong, although our wheel bearings have only just started mass production in recent months, we have a very long history of researching wheel bearings."

"And we have recruited a lot of people into the R&D center in the past year."

"Today, we have more than 200 employees in our R&D center."

"Hundreds of new college students will start to join the company, and the strength of the R&D center will be even stronger."

"Even we are cooperating with Lingnan University of Science and Technology, Guanggong and other schools to study some parts in advance."

"Of course, there must be some of our know-hows in this, and it's not easy to say that it's particularly specific."

"There are even some things that are the same, such as the heat treatment process of special steel, whether it is in the production of bolts or the production of bearing components, it will be involved."

Nine of Zhang Fugui's ten sentences are true, sandwiched between a false sentence.

True and false, Bu Defan and Li Jianfeng naturally can't tell the difference clearly.

However, this also reminded Cao Yang, who was sitting next to him, that the scale of the R&D center should be expanded at a faster pace.

Even if it is a waste of some money, it is necessary to make the scene up.

Otherwise, if you take out the gearbox or steering gear yourself in the future, how can you explain the source of the technology?

If there are thousands of people in the R&D center, then everyone's doubts will be much less.

More or less, it can also bring some real progress to Nanshan Technology Co., Ltd.

If Nanshan wants to become the world's No. 1 auto parts supplier, it is absolutely impossible for him to do it alone.

After returning to Yangcheng this time, the construction of talents, especially the recruitment of leading talents, must be carried out.

"Mr. Cao, this hub bearing of yours, we will also analyze it internally."

"At that time, we will also cooperate with the people of the quality management department to visit the site."

"If it is really better than SKF's imported parts, then we are not without the possibility of cooperation."

Bu Defan is not a procrastinator.

The situation is now relatively clear.

Then the use of Nanshan's hub bearings is on the agenda.

Even like the nut plate, it is not impossible to consider letting Volkswagen headquarters import part of it from Nanshan.

The premise is that the quality of Nanshan's hub bearings is really so good, and there is no problem with quality stability.

"Mr. Bu Defan, thank you for your continued support to Nanshan Technology Co., Ltd."

"We are always looking forward to your experts."

"We have absolute confidence in the wheel bearings we produce."

"Whether it is SKF or NTN, or the domestic Wanxiang and Renben, it is impossible to produce products with better quality and lower cost than ours."

"I look forward to more opportunities for Nanshan to provide parts for the public of Modu."

Cao Yang clearly felt that Bu Defan's respect for Nanshan had improved.

Sure enough, strength is the only way to win respect.

If Nanshan's test report is very stretchy today, it is estimated that the other party will not have the patience to talk to you in detail at all.
