Slewing Rings for Excavator Feature: The speed of Slewing bearing is fairly low, usually below 10 r/min. Moreover, on most occasions, Slewing bearing doesn¡¯t slew continually, but only slew back and force in a certain angle like the so called Swing Bearing. Slewing bearing differs greatly from roller bearing in process techniques, material and heat treatment. Generally, Slewing bearing has gear ring as driving device and Seal Device to pretend dust. Unlike the common bearing fixed on the central pivot in the bearing box, Slewing bearing has big size and is attached to upper and lower plates by bolts. Application:Slewing bearing is widely used in different industries. It is suitable for hoisting machine (truck crane, tower crane, etc.), construction machinery (excavator, loading and unloading machine), transporting machine, material processing machine, Metallurgy Machinery, food processing machine, military product (tank, santi-aircraft gun, radar, missile launcher, etc.), medical instrument research equipment, etc. BA152-2036 150 203 26
