Excavator slewing bearing FAQS

QWhat is Raw material?

AOur excavator slewing bearings are made of high quality bar steel of 50Mn or 42CrMo which forged into bearing rings strictly accordance with the national standards of forging.

QWhat is Raceway hardening?

AThe bearing groove is quenched by the advanced automatic tracking induction quenching equipment, which can accurately control the quenching hardness and hardening depth of the groove, and ensure the slewing bearings are firm and durable.

QWhat is Gear hardening?

AThe single tooth quenching is adopted to ensure that the tooth surface and groove reach the standard quenching hardness and the inside of the tooth is soft, which guarantees the high wear resistance and impact resistance of the teeth, greatly improves the life of the teeth and reduces the risk of broken teeth.

QWhat is features of Slewing bearing?

ADepending on their design, slewing bearings have the following features: High load carrying capacity High stiffness for rigid bearing application Low friction Long service life Surface protection and corrosion resistance Integration of additional features, including: driving mechanism control devices lubrication systems monitoring systems sealing cassettes
