The slewing bearing (reverse bearing) slewing bearing, also known as the reverse bearing; is a large bearing that can accept the induction load; it can accept large axial, radial load and overturning moment together. The slewing bearing usually has equipment holes, Internal or external gears, smooth oil holes and sealing equipment; therefore, the host can be drawn in a compact layout; the guide is simple; the protection is simple. The slewing bearing has a toothless type; the external gear and the internal gear type four-point touch ball bearing, double row The angular touch ball bearing is inserted into four series of cylindrical roller bearings, inserted tapered roller bearings and three rows of cylindrical roller composite bearings; the four-point touch ball bearing has high static load ability; the inserted cylindrical roller has a high degree of teaching. Dynamic load capability; pre-interference of the inserted tapered roller bearing can make the bearing have greater support rigidity and reverse precision; the three-row cylindrical roller combined bearing leads to the bearing height due to the improvement of bearing capacity; The same raceway accepts; so the same force situation; its bearing diameter can be greatly reduced. 蚨惺 骰咏舸盏 骰咏舸盏 骰咏舸盏 氐闶 恢 恢 恢 恢 恢 恢 恢 恢 恢 转盘 转盘 转盘 转盘 转盘 转盘 转盘 转盘 转盘It is also capable of depicting, developing and producing various types of equipment such as lifting machinery, mining machinery, construction machinery, port machinery, ship machinery and high-precision equipment such as radar machinery and missile launchers.
