The slewing bearings are comprised of two rings, each of which contains a precision raceway that is induction hardened on the surface to a specified depth. Each ring is made from a medium carbon steel forging.slewing bearings have raceways constructed in a four-point contact configuration, with 45° contact angles as standard. Other raceway configurations are available, such as crossed roller and Four-point contact. These other options are often considered in cases where very high loads or special stiffness requirements are needed.
Slewing bearings are necessary when in a given machine or system, one structural part needs to rotate in the opposite direction to another along a fixed axis, whilst guaranteeing the axial and radial link between the two parts.
The Light weight slewing Bearing has the same structure with ordinary slewing bearing,but the weight is light,and rotate flexibly.
Light weight slewing bearing application:
1.Food machinaery,
2.Canning machinery
3.Environmental machinery etc.
