The importance of slewing ring bearing maintenance in lifting …

The use of a slewing ring bearing provides yet another benefit: its shaftless design eliminates the need for a spindle or kingpost. The center of the bearing remains open to allow passage of various hydraulic and control components. Since the bearing is so critical, careful maintenance is necessary. More than 96% of slewing ring bearing

Slewing Bearing Material - GCr15, 50Mn, 42CrMo Characteristics

20/6/2019· 50Mn and 42CrMo Steel. For slewing bearing material, BRS usually use 50Mn or 42CrMo as the raw material. 50Mn is a high quality carbon structural steel. It has high strength, elasticity and hardness, often used after quenching and tempering. The welding performance of 50Mn is poor, and it has a tendency to overheat sensitivity and temper

Slewing Bearings, स्लूयिंग बियरिंग्स in Kolkata , Mines …

Premature failure is a common fate for large-diameter bearings in heavy-duty appliions where rotations are frequent. In big rotating equipment such as cranes, excavators, and tunnel boring machines, a slewing ring bearing must simultaneously handle a complex load spectrum that covers diverse coinations of thrust, radial and tilting moment loading.

3 Common causes of bolt failure | Boltstress Ultrasonics

3 Common causes of bolt failure. Most mill operators are familiar with (and regularly go through) a process known as re-torque. Re-torque is an expensive exercise resulting in lost production, but is believed to be necessary in order to avoid bolt failures that cause unplanned shutdowns. It doesn''t have to be this way however, by eliminating
