The so-called distributor's general factory generally refers to ZWZ brand, but Wazhou Group does have a branch factory, but the factory brand is ZWZ. The quality is better. The so-called branch factory of dealers refers to the private bearing factory in Wafangdian area, with good and bad quality. Some large and some small private bearing factories can really compete with tile shafts in product quality, or have good cost performance. But there are indeed some bearing factory products that are sloppy.

If you are not short of money, choose ZWZ (pay attention to fakes, the quality of goods replaced by ZWZ is average). If you consider the cost performance, recommend some large private bearing factories, which won't let you down. Or just lucky. If you have a batch, you can go to Wafangdian for a field trip. Don't push down the price, stick to the quality, you won't be disappointed.
