Stainless Steel Bearing Cover
Doesn’t the product in my hand look a bit like a faucet connected to a water pipe at first glance? In fact, upon closer inspection, it is still very special and not an ordinary pipe connection. It is a bearing cover applied in the dough kneading machine of household appliances. Today, let’s take a look at what the stainless steel bearing cover made by powder metallurgy pressing forming process looks like? There is a protruding arc-shaped step on the bottom surface. On the outside, there is a concave ring and a section of screw thread respectively. On the inside, from top to bottom, there are three steps of different sizes at different parts. Although the thread is machined and turned out, all other shapes and sizes are formed in one time by molds, which minimizes material waste to the greatest extent, especially reducing a large amount of machining costs and increasing the efficiency of batch production. Another aspect is the oil content of the porous structure of powder metallurgy. Under the principle of thermal expansion and contraction at high speeds, its self-lubricating function can significantly extend the service life of the product.
