Yaw Bearing of Wind Turbine Generator
The yaw bearing must cope with enormous static and dynamic loads and moments during the wind turbine operation, and provide smooth rotation characteristics for the orientation of the nacelle under all weather conditions. The yaw bearing is the most crucial and cost intensive component of a yaw system found on modern horizontal axis wind turbines. It should last for the service life of the wind turbine) while being cost effective. It has also to be corrosion and wear resistant and extremely long lasting.
The Kinds of Wind Turbine Bearings of LDB Company
There are two kinds of wind turbine bearings in Luoyang Longda Bearing Co., LTD., that are wind turbine main shaft bearing and blade bearing of wind turbine generator. According to clients' demands, our range of wind turbine blade bearing is available as internal geared, external geared, or gearless types. Other types of wind turbine bearings such as yaw bearing and main shaft bearing are also available.

The Tapper Roller Bearing Brief Introduction
Tapered roller bearing belongs to separable bearing. The roller, cage and inner ring constitute as cone. The cone could be mounted separately with outer ring. The raceway of inner ring and outer ring is tapered and could fill taper roller. This type of bearing could carry radial and axial jointed load. The bearing axial load is determined by contact angular ( raceway angular of outer ring). The bigger the, the heaver of axial load carried. According to the number of row of rollers, this type of bearing could be divided into single, double and four row tapered roller bearing.
Bearing Application for Wind Power
Wind turbine bearings can be roughly divided into three categories: yaw bearings, pitch bearings, transmission bearings (spindle and gearbox bearings).The yaw bearing is installed in the junction of the tower and the cockpit pitch bearings installed in each blade root and the hub joints, the main secrets within the internal drive system bearings cylindrical roller bearings, tapered roller bearings and high-quality self-aligning roller bearings. Each wind turbine equipment with a yaw bearing and three sets of pitch bearings.

The Slewing Bearing Application in Engineering Machinery
Engineering machinery has crane, excavator, bulldozer, roller, carried earth machine, engineering machine working conditions, dust, load heavy, mechanical fault, working hours long.
LDB bearing can provide you with CATERPILLAR slewing bearing, KOMATSU slewing bearing, HITACHI slewing bearing, SUMITOMO slewing bearing, KOBELCO slewing bearing, DAEWOO slewing bearing and HYUNDAI slewing bearing, which will have a load capacity, high performance, the advantages of long life, can ensure that equipment in a harsh environment smooth operation.
The Cylindrical Bearing Application in Metallurgical Industry
The four cylindrical roller bearings and six cylindrical roller bearings almost entirely for the roll neck rolling rack, roller and rolling press. Compared with other roller bearings, the friction of these bearings. These bearings are usually installed on the roll neck, interference fit, particularly suitable for rolling high-speed rolling mill applications. The low cross-section of these bearings allows the use of relatively large compared with the diameter of the roll roll neck diameter. Can be put into a very large roller, radial load capacity is very high.
A considerable extent simplifies the bearing installation, maintenance and inspection. Bearing can withstand a certain limit shaft relative to the bearing axial displacement. The four cylindrical roller bearings with a cylindrical hole, some size bearings can also supply with a conical bore. Bearings with tapered bore can be adjusted during the installation process to get a certain amount of radial internal clearance or determine the pre-load.

YRT bearing is very popular in bearing market
Axial/radial bearings YRT, RTC and YRT Speed and axial angular contact ball bearings ZKLDF are ready-to-fit high precision bearings for high precision applications with combined loads. They can support radial loads, axial loads from both sides and tilting moments without clearance and are particularly suitable for bearing arrangements with high requirements for running accuracy, such as rotary tables, face plates, milling heads and reversible clamps.
Due to the fixing holes in the bearing rings, the units are very easy to fit.
Split Bearing is a Special Bearing on the Basic of Whole Bearing
Split Bearing is on the basis of the whole bearing via special designing and processing. It’s features as followed, small working resistance, operate steadily, working test up to 1800C, It is very suitable for low speed, overloading,large impact, poor sealing performance occasions. Its biggest advantage is to easily and quickly fix, saving considerable time and lowering production costs without remove the original coaxial bearing.
Split bearings can be used for all industrial areas, mainly in the converter bearing, large-scale transportation equipment, in conjunction casting roller bearing, elevator and feed carrier, paper manufacturing machinery, and the place hardly to remove.

The Application of Wind Turbine Bearing in Wind Power Industry
Wind turbines is a kind of green and sustainable energy. The yaw bearings and blade bearings we design and manufacture are important parts of a wind turbines generator, they help the rotor blades rotate easily in the wind and transform kinetic energy into electric power.
Wind Turbine Bearing Is Developed With the Development of New Energy
Green, clean energy needs of the advanced product support. The LDB closely follow the development trend of wind power committed to the development and manufacturing of wind turbine bearings have been formed from 600KW-2.0 MW unit with yaw bearings, blade (pitch) bearings, spindle bearings, gearbox bearings development manufacturing capabilities, providing customers with a series of bearings used by wind turbine.
What about the spherical ball bearing
Spherical ball bearing is another kind of spherical ball bearing. The outer ring has a spherical raceway for sharing, and the inner ring has 2 raceways which are inclined by certain angel to the bearing axis, so the bearing can be self aligned.

When the axis is bended upon force exercised on it, or the axis is with different axial parts in it, the bearing still functions normally. This kind of bearing can bear not only radial load, but also bilateral axial load. With high impact resistance, spherical ball bearing’s limit rotational speed is low.

Why People Choose LDB Spherical Roller Bearing
By the shape of cross section, spherical roller bearing can be split into 2 types: convex symmetrical roller and convex asymmetrical roller. Convex asymmetrical roller was a kind of early product. Compared with the early products, convex symmetrical roller can bear heavier axial load, work at a lower temperature and a higher rotational speed, because the internal structure and the parameters of the convex symmetrical roller have overall been designed better.
By the cages and depressed parts, spherical roller bearing can be split into 2 types: type C and type CA. Type C is of pressed steel cage without depressed parts, and type CA is of solid cage with depressed parts.
Spherical roller bearing is used to bear heavy load. This kind of bearing is double-row. The outer ring has a spherical raceway for sharing, and the inner ring has 2 raceways which are inclined by certain angel to the bearing axis, so the bearing can be self aligned. When the axis is bended upon force exercised on it, or the axis is with different axial parts in it, the bearing still functions normally. This kind of bearing can bear not only radial load, but also bilateral axial load. With high impact resistance, spherical roller bearing’s limit rotational speed is low.
Slewing Drive is the Star Product of LDB
Introduction
Slewing drive is consist of slewing bearing,worm shaft,housing,bearing,motor and so on. Motor drive the worm shaft, the outer ring of slewing bearing will rotate, the outer ring output the torque through flange while the inner ring of slewing bearing is fixed in housing.
Function
Slewing drive is able to sustain more axial load, radial load and tilting moment.Turntable or frame rotate at azimuth and elevation driven by slewing drive.
Application
●For Solar:It is designed in solar tracking system and improve power generation efficiency.
●For industrial usage: Mainly used to drive two relative rotating objects in 360°.
