Types of bearings in the construction machinery industry

I. Special bearings for Special Working Conditions

Youdaoplaceholder0 thrust roller bearing ‌

Youdaoplaceholder0 function ‌ : Pure axial load, suitable for heavy-duty pressure equipment

Youdaoplaceholder0 scene ‌ : Support structure of a road roller, column of a large press

Youdaoplaceholder0 needle roller bearing ‌

Youdaoplaceholder0 Features ‌ : small cross-section, high load density

Youdaoplaceholder0 application ‌ : piston rods of hydraulic cylinders, joints of compact walking devices

Youdaoplaceholder0 crossed roller bearing ‌

Youdaoplaceholder0 Advantages ‌ : Bidirectional load-bearing, rotational accuracy ≤0.005mm

Youdaoplaceholder0 field ‌ : industrial robot joints, CNC welding turntables

Ii. Key Parameters for Selection

Youdaoplaceholder0 load type ‌ :

Radial dominant → cylindrical roller bearing (N series) ‌

Axial + radial compound → tapered roller bearing (3 series) ‌

Impact load → self-aligning roller bearing (22 series) ‌

Youdaoplaceholder0 environmental adaptability ‌ :

Dust → Rubber seal design (suffix 2RS) ‌

High-temperature → special heat-treated steel (suffix HT) ‌

Iii. Direction of Technological Evolution

Youdaoplaceholder0 Material innovation ‌ : The fatigue life of rare earth steel bearings has been increased by 40 times, and ceramic ball bearings are suitable for high-speed scenarios

Youdaoplaceholder0 Intelligence ‌ : Integrated temperature and vibration sensors to achieve pre-maintenance (such as online diagnosis of wind power bearings) ‌

Youdaoplaceholder0 Note ‌ : For extreme working conditions such as shield machines and mine crushers, non-standard bearings need to be customized. Special designs based on load spectra and thermal deformation parameters should be provided
