External Gear Teeth Machining Efficiency for Single Row Four Point Contact Ball Slewing Bearing Price

Single Row Four Point Contact Ball Slewing Bearing

The slewing bearing takes a lot of time from the forging to the finished product until it is sent to the user's hand. The delivery time depends largely on the processing efficiency of the slewing bearing.

In recent years, in order to adapt to the improvement of machining precision and production efficiency in slewing bearing processing, hobbing technology has been developing in the direction of full CNC, zero transmission, high speed, high precision and intelligence. Hobbing processing volume is 45% or even larger for the entire slewing bearing, and for the large-diameter, large-modulus slewing bearing processing, the milling processing also shows the characteristics of good machining precision, high efficiency and convenient programming.

The slewing bearing is a large-sized bearing with low speed and heavy load operation. Usually, the inner ring or the outer ring is toothed. It is used to connect two large parts that need relative rotation. The slewing bearing is widely used in engineering machinery, wind power equipment, port machinery and other fields. In recent years, due to the country's strong investment in infrastructure, new energy equipment and other fields, the market demand for slewing bearings has also increased sharply, and there is often a shortage of supply. On the other hand, there are many domestic slewing bearing manufacturers, especially in Xuzhou,To stand out, minimizing costs under the premise of ensuring product quality is the key to the company's emergence in the fierce market competition.
