Product Feature

Able to withstand the large axial load, radial load and overturning moment consolidated loads, with support, rotation, transmission, fixed and other features

Applications

Slewing in modern industrial applications is very wide, known as: "the machine joints." Is the need for relative rotational movement between two objects, but also need to withstand the axial force, radial force, tipping the important moments of the mechanical drive components required. With the rapid development of machinery industry, slewing ring in marine equipment, construction machinery, light machinery, metallurgical machinery, medical machinery, industrial machinery and other industries has been widely used.

Product Details

 

Product details:

Slewing ring bearing turntable called , some people call it : rotary support , swing support . Wheel bearings usually consists of inner and outer rings , rolling , spacers , seals and other parts. English names were called : slewing bearing, slewing ring bearing, turntable bearing, slewing ring.

Internal structure is divided into:

Single-row four point contact ball slewing bearings, double -row ball slewing bearings, single row cross roller slewing bearing , three -row roller wheel bearings, ball bearings, wheel cylinder hybrid . The shape is divided into: the gear, external gear , no gear and so on. Slewing ring of material is generally high carbon steel ( such as 50,55,60,50 Mn, 42CrMo , etc. and POM reinforced plastics.

Wheel bearings can withstand a large axial load, radial load and overturning moment consolidated load, set support , rotation, transmission, fixed and other functions in one . Under normal circumstances, the wheel bearing itself generally with mounting holes , lubricants and seals, to meet the different needs of a variety of different conditions of work under the conditions of the various types of hosts ; hand, turntable bearing itself has a compact guide rotating convenient, easy to install and easy to maintain , etc. , are widely used for lifting and transport machinery , mining machines, excavators , construction machinery , port machinery , wind energy , medical equipment , radar and missile launchers and other rotating equipment .

Single-row four point contact ball bearing turntable mainly by the inner and outer rings , balls , isolated block of four major components, compact, light weight , and circular raceway ball four point contact , can withstand the axial force , radial force , overturning moment consolidated loads. Rotary conveyors, welding machine , small cranes and excavators and other construction machinery can be used.

Double row ball bearing turntable has three races , ball and isolation blocks can be directly discharged into the upper and lower raceway, according to the situation by force , arranged in two rows down different diameter steel balls. This assembly is very easy to open , carrying angle of both the upper and lower raceway arc is 90 °, can withstand large axial forces and tilting moments. When the axial force is greater than 0.1 times the radial force , the roller must be specially designed . Double row ball slewing bearing axial and radial dimensions are large, structural tightening . Especially for applications that require above average diameter of tower cranes, truck cranes and other handling machinery.

Single row cross roller slewing bearing , consisting of two races , compact, light weight, high manufacturing precision , small assembly space for installing high precision cross roller arrangement is 1:1 , can withstand axial force , overturning moment and larger radial force , is widely on lifting the transport, engineering machinery and military products are used .

Three -row roller slewing bearing has three seat , down and radial raceway separate from each other so that each row roller load can be determined exactly . Able to withstand the various loads , carrying capacity is four products in one of the largest , axial and radial dimensions are large , firm structure, particularly for applications that require larger diameter heavy machinery, such as bucket wheel excavators, wheel cranes , marine cranes, port cranes , steel work stations and large-tonnage truck cranes and other machinery.

Lightweight wheel bearing slewing ring has the same general structure, light weight , flexible rotation . Widely used in food machinery, filling machinery, environmental protection machinery and other fields. Lightweight Single-row four point contact ball bearing turntable composed of two races , compact and circular raceway ball four point contact . Mainly for truck cranes, tower cranes, excavators, pile drivers , construction vehicles, radar scanning equipment to withstand the overturning moment , vertical axial force levels tend to force the machinery. Lightweight single row cross roller slewing bearings, composed by two seat , compact structure, high manufacturing precision , small assembly space for installing high precision cross roller arrangement is 1:1 , can withstand the axial force , overturning moment and larger radial force , which is widely on transport, engineering machinery and military products are used .

Installation Notes:

Front wheel bearings installed , first for the host to check the mounting surface , requiring support should have sufficient strength , connecting surface should be machined smooth surface free of debris and burrs. For the flatness can not achieve the required machining , the injection can be used to make large -strength special plastic filler , to ensure the accuracy of the mounting surface and means for damping .

Turntable bearing rings have hardened soft band , which in the end face of the ferrule are labeled "S", the software should be installed so that the position be placed with non- load area or extraordinary load area ( plug hole is always located in the soft with the Department ) .

When installing wheel bearing , should act to advanced positioning, cross- tighten the mounting bolts , and check the condition of the bearing rotation . Tighten the bolts should have enough preload, which should bolt preload material yield 70% limit . Mounting bolts should be equipped with tempered flat washer and spring washer is strictly prohibited .

Lubrication during use , subject to the instructions require periodic lubrication , lack of lubrication to avoid leaving early failure slewing
