How to select bearings for construction machinery based on working conditions

I. Load type leading selection
Youdaoplaceholder0 Load characteristics ‌ ‌ bearing type ‌ ‌ advantages ‌ ‌ typical cases ‌
Youdaoplaceholder0 Heavy radial load + impact ‌ self-aligning roller bearing automatically compensates for shaft deviation ≤2°, raceway adaptive stress distribution vibrating screen main shaft ‌
Youdaoplaceholder0 Combined load (radial + axial) ‌ tapered roller bearing (contact Angle > 25°) line contact design to disperse stress, flange structure to withstand bidirectional axial force excavator hub ‌
Youdaoplaceholder0 super large pure axial load ‌ thrust cylindrical roller bearing with densely arranged flat rollers, axial load-carrying capacity increased by 50% ‌ hydraulic cylinder thrust support
Youdaoplaceholder0 light-load high-speed ‌ angular contact ball bearings (paired DB) with precision raceways and grease lubrication, maximum speed > 10,000 r/min pump drive shaft ‌
Second, enhanced design for environmental adaptability
Youdaoplaceholder0 sealing and anti-pollution solution ‌
Youdaoplaceholder0 Dust environment ‌ : iron cover seal (ZZ type) + labyrinth groove structure, blocking particles with a diameter greater than 10μm ‌
Youdaoplaceholder0 water vapor environment ‌ : rubber sealing ring (2RS type) + anti-rust coating, IP65 protection grade
Youdaoplaceholder0 High-temperature working conditions ‌ : fluoroether rubber seal + polyurea grease, temperature resistance > 150℃
Youdaoplaceholder0 Material upgrade ‌
The hardness of carburized steel rollers is HRC 60-64, and the impact life is increased by 30% ‌
Ceramic rolling elements (Si₃N₄) are used in electrochemical corrosion environments ‌
