In mining equipment, large bearings are core components that support heavy loads and withstand extreme working conditions such as shock, vibration, dust and high humidity. Their reliability and durability directly affect the production efficiency and maintenance costs of the equipment. The following Read More

Gear steels may be divided into two general classes — the plain carbon and the alloy steels. Alloy steels are used to some extent in the industrial field, but heat-treated plain carbon steels are far more common. The use of untreated alloy steels for gears is seldom, if ever, justified, and then, on Read More
