Product Description

Large Size Bearing/Turntable Bearing/Internal Gear Slewing Ring Bearing/YRT bearing/cross roller bearing for Deck Crane, Wind Power and Machinery Construction Product Description

ZYS slewing bearings can be divided into the following types according to their structures as single row four point contact ball slewing bearing, single row cross roller slewing bearing, double row different ball diameter slewing bearing, three row cylindrical roller slewing bearing and roller/ball combination slewing bearing. These types of bearings can be further divided into bearings without gears, bearings with external gears and bearings with internal gears.

Slewing bearing typeSingle row four point contact ball slewing bearing This kind of slewing bearings can support high dynamic loads, transmitting axial and radial forces simultaneously as well as the resulting tilting moments. Applications of this kind of bearings are hoisting, mechanical handling and general mechanical engineering etc.Single row cross roller slewing bearing This kind of bearings can support combinations of large radial force, medium axial force and tilting moment with small or zero clearance. Main applications of this kind of bearings are hoisting and mechanical handling and general mechanical engineering etc.Double row different ball diameter slewing bearing This kind of bearings can support high static loads with simple structures. They are mainly used in situations with variational load position and direction and continuously rotating. Main applications of this kind of bearings are deck hoisting, mining and material handling etc.Three row cylindrical roller slewing bearing This kind of bearings has high load carrying capacity. Under same loads, this kind of bearings has much smaller diameters which can make the installation much compact, as different kinds of loads are supported by different races and rollers. Main applications of this kind of bearings are hoisting, mechanical handling, mining and materials handling, offshore technology and general mechanical engineering etc.Roller/ball combination slewing bearings This kind of bearings can support high axial load and low tilting moments. Usually they are large diameter slewing bearings. Applications of this kind of bearings are mining and materials handling etc.Materials of slewing bearing 1. Material of slewing ring: 42CrMo is generally used for ZYS slewing ring with surface quenching treatment of the raceway. Other kinds of surface quenched steel can also be used according to customer specification and operating conditions.2. Material of rolling element: The material of rolling elements in ZYS bearing is GCr15 or GCr15SiMn steel.3. Material of cage: Various types of cage are used in ZYS slewing bearing, which can be divided into integrated cage, segmented cage, spacer and etc. 20 steel or ZL102 cast aluminum alloy is used for integrated cage and segmented cage. For spacer,the material is polyamide 1010 resin, ZL102 aluminum bronze, QA110-3-1.5 aluminum bronze or GRPA66-25 nylon. 4. Material of sealing ring: The sealing ring is made of NBR.Company Profile
