double row different ball size slewing bearing without gear 020.25.500
Turntable bearing, also known as slewing bearing, is a kind of large bearing which can bear large axial load, radial load and overturning moment at the same time. Turntable bearings are usually equipped with mounting holes, internal or external gears, lubricating oil holes and sealing devices, so that the main engine structure design is compact, the guide is reliable and the maintenance is convenient.
There are four point contact ball bearings with or without teeth, external teeth and internal teeth, double row angular contact ball bearings, cross cylindrical roller bearings, cross tapered roller bearings and three row cylindrical roller combined rotary bearings. Among them, four point contact ball bearing has higher static load capacity; cross cylindrical roller bearing has higher dynamic load capacity; cross tapered roller bearing can make bearing have greater support rigidity and higher rotation accuracy through pre interference.
Rotary bearing is widely used in hoisting machinery, mining machinery, construction machinery, port machinery, ship machinery, high-precision radar machinery and missile launcher and other large rotary devices.
Truck Crane Used Slewing Ring Bearing
Various types of engineering cranes are usually composed of four parts: working mechanism, metal structure, power plant and control system.
Following we will introduce the working mechanism of the crane. It includes four parts: lifting mechanism, luffing mechanism, slewing mechanism and walking mechanism.
The slewing mechanism consists of a drive device and a slewing bearing
Hot-selling Slew Bearing Ring Price - DOUBLE FLANGE SLEWING BEARINGS WITH SINGLE BALL BEARING ROW, NO GEAR TEETH, STANDARD 230 SERIES – Wanda
The flange slewing ring has the same structure with four points contact ball slewing bearing, but the weight is lighter; the outer or inner ring of the flanged slewing bearing has the “L” edge, like a flange, that’s why we called it flange type bearing. Flange light slewing bearing ring is also used for some applications which has weight limit for the bearing, the weight for the flange type slewing ring is much lower than normal type. The materials of the flange slewing ring are mainly ...
