The traditional slewing bearing gear products are mostly involute cylindrical gears. With the higher requirements in the product performance like load bearing capacity, service life and drive efficiency, the traditional products cannot meet customer’s requirements any more.

After years of efforts, Maanshan Fangyuan Slewing Ring Co., Ltd.(FY Slewing Ring) has designed the drum gear slewing bearing according to the work condition of the machine. Compared with the traditional products, the drum gear slewing bearing improves the transmission torque by more than 30%. It features long service life, smooth transmission, low noise and the transmission efficiency of up to 99.7%. And it is more reliable, easy to maintain, convenient to disassemble, which greatly reduces the cost.

At present, the drum gear type slewing bearing products have been applied in various construction machinery products like excavator, truck crane, tower crane, etc.
