  • Shield Machine Slewing Bearing

    Tunnel boring machine as known as shield machine, is the main construction machinery in the process of shield construction. It must have high reliability and be able to work steadily and reliably. The main bearings of large-scale shield machine mostly adopt three rows roller slewing bearings, which need to bear large axial force and overturning moment, and also bear certain radial force. The loading situation is complex, and it is easy to produce large deformation, which affects the construction safety of the shield machine. The slewing includes an upper ring and a lower ring. The upper ring is connected with the lower ring by bolts to form an outer ring structure. The gear ring is located in the inner ring structure. The side of the gear ring is provided with a convex platform. The upper ring and upper ring of the convex platform are provided with an upper raceway, the upper raceway is equipped with an upper row of rollers, the lower raceway is equipped with a lower row of rollers, and the side and outer ring of the convex platform are equipped with a lower row of rollers. There is a radial raceway between them, and a radial roller is arranged in the radial raceway. The inner edge of the upper ring and the upper end of the gear ring are connected with double sealing rings, and the lower end of the gear ring is connected with a lower sealing belt.

  • Customizable large turntable bearings

    Turntable bearings, also called slewing bearings, are key components in mechanical equipment. Its features include strong load-bearing capacity, smooth operation and high precision. It mainly consists of an inner ring, an outer ring, rolling elements and a cage. The inner ring and outer ring transmit torque and bear load through rolling elements to realize the rotary motion of the equipment. It is widely used in heavy machinery, wind power, port equipment and other fields. Its excellent performance ensures the efficient and stable operation of the equipment and provides strong support for the development of modern industry. HGB Company manufactures standard and custom slewing bearings in various designs with outer diameters from 200mm-10000mm to meet the requirements of specific applications.

  • Gold medal merchants manufacture turntable bearings

    Slewing bearing is an important "joint" of the crane. Various loads and moments on the working device need to be transmitted to the chassis through the slewing bearing. Because the slewing bearing is overloaded, it is also the part where the crane is prone to failure, so it is necessary to install a new slewing bearing after long-term use. Truck cranes, crawler cranes and other heavy construction cranes are usually using large single row four-point contact ball slewing ring bearing. This type of slewing bearing can bear larger axial load, radial load and tilting moment, enabling crane to lift heavy loads stably and reliably.

  • Single Row Cross Roller Slewing Ring Turntable Bearing (HJ Series)

    The single-row cross-roller slewing bearing consists of two rings, with compact structure, high manufacturing accuracy, small assembly clearance, and high requirements for installation accuracy. It can bear overturning moment and large radial force and it is widely used in transportation, construction machinery and military products. There are two basic working modes: 1. The inner ring fixes , and the outer ring rotates; 2. The outer ring fixes and the inner ring rotates. The raceways of the slewing bearing are all treated by surface induction hardening, and the quenching hardness is guaranteed to be HRC55~62, which can achieve sufficient hardened layer depth. Slewing bearing is usually made with internal teeth, external teeth or no teeth. The heat treatment of gears is generally normalized or quenched and tempered. The tooth surface can also be quenched according to the user's requirements, the quenching hardness is HRC50-60, and sufficient depth can be guaranteed. Teeth grinding is also supported.
