teräspallo

Teräspallo is a Finnish term that translates to "steel ball" in English. It refers to a solid spherical object made from steel. These balls are manufactured to precise specifications for a variety of applications.

The primary uses of teräspallo are found in mechanical systems. They are essential components in ball bearings, where their smooth, hard surface allows for low-friction rotation between two moving parts. This significantly reduces wear and tear and increases the efficiency of machinery, from simple household appliances to complex industrial equipment.

Beyond bearings, teräspallo are also utilized in other areas. They can be found in certain types of valves for controlling fluid flow, as counterweights in various mechanisms, and as projectiles in some forms of ammunition or recreational devices like slingshots. In some industrial processes, they are used for grinding or polishing other materials, a technique known as ball milling.

The properties of teräspallo depend on the type of steel used in their production. Common materials include carbon steel, stainless steel, and alloy steels, each offering different levels of hardness, corrosion resistance, and strength. The manufacturing process typically involves forging, grinding, and polishing to achieve the desired dimensional accuracy and surface finish.
