What are the types of construction machinery bearing?
Some types of construction machinery bearing 1. Needle bearing Needle bearing: The needle roller bearing is equipped with thin and long rollers, which is especially suitable for the support structure with limited radial installation size. The needle roller bearing can be used without inner ring bearing or needle roller and cage assembly according to different occasions. 2. Self-aligning ball bearings Self-aligning ball bearings: Between the inner ring of the two raceways and the outer ring with a spherical raceway, a drum-shaped roller bearing is assembled. It has the same self-aligning function as self-aligning ball bearings. When the shaft and casing deflect, it can be adjusted automatically without increasing the bearing burden. Spherical roller bearings can withstand radial loads and axial loads in two directions. 3. Working principle of deep groove ball bearing: Deep groove ball bearings mainly bear radial loads. When they only bear radial loads, the contact angl...
