Double Row Ball Slewing Bearing-internal Toothed

Double Row Ball Slewing Bearing-internal Toothed

Introduction

LYDZ 021 series are eight-point contact ball bearings, invented by DZE, which can withstand higher loads when using the same diameter rings and bolts. Compared with single-row four-point contact balls, bearing double row load capacity is increased by 80%, and the lateral dimensions are more compact than three-row roller bearings.DZE is a luoyang bearing co itd. DZE can roller contact bearing shells,bearing double row made factory.

Design Features

This series of bearings has double-row deep groove raceways on the inner and outer rings, and each raceway is equipped with the largest size ball. structure allows the bearing balls to have 8 contact points at all times, which can obtain higher torque, thrust and radial force load-bearing capacity. After precision machining, the raceways and balls are precisely matched to achieve uniform load distribution. Perfect sealing can prevent contamination and impurities from invading.

*S T D: Standard series size;

*S L: Light series size;

*SLBP: Light series size without flange structure;

*In addition to the above models, if you want to customize non-standard bearing products, please contact: 13700810892, we will provide you with a design plan.

Supply Capacity

LYDZ 021 bearing double row bearings are made to order and can provide customized bearing hole types. Internal gear type, external gear type and other mechanical drive structure forms can be made according to requirements. DZE luoyang bearing co itd  have 13 years of manufacturing experience.We can manufacture bearing shells,roller contact bearing.

Application Range

Bearing double row  are widely used in heavy load occasions, including:

●Large excavators

●Large cranes

●Large telescopes

Luoyang East Bearing Co., Ltd. specifically produces pre -loaded cross -rolling bearing and turntable bearings. 

The production process adopts the grinding process and the host supporting design scheme. Ensure that the bearing reaches high precision level and service life within the range of service life. 

Since its establishment in 2012, special bearing and precision rolling rollers with special bearing and precision rolling rollers have been designed and manufactured since its establishment in 2012. 

The structure includes: RU series, RB series, RA series, RE series, CRBH series, SX series; precision turntable bearing structures include: structure series include toothless Lydz00 series, Lydz11 series, LYDZ020 series; Series, outer teeth LYDZ01 series, lydz11 series, LYDZ021 series; YRT to the bearing YRT series, YRTS series, YRTM series. Suitable for all mechanical transmission industries. 

The precision cross-rolling bearing we produce, forgedings use bearing steel GCR15; GCR15SIMN has been quenched, recovered, and the hardness of the annealing treatment reaches HRC56-62, the mechanical performance is stable, and the service life is more than 10 years. The east bearing provides special requirements for stainless steel, hard aluminum non -calibrating bearing. 60%of the precision cross - roller bearing exports to 65 countries; 

since the company was established in 2012, we produced more than 800,000 sets of precision cross -rolling bearing and precision turntable bearings; The manufacturing equipment and perfect after -sales service team owned by the east bearing, high -precision plane grinding machine, high precision outer round grinding bed, high -precision internal round grinding beds ensure the accuracy of production products; And analysis. The LYDZC engineering and design departments use new computing software and finite element analysis to provide you with innovative and customized solutions that meet harsh specifications. 

Various standard roller rotor bearing and roller cross -rolling bearings are also constantly inventory, which meets your emergency needs at any time.
