What are the 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 angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can bear a large axial load. The friction coefficient of the deep groove ball bearing is very small, and the limit speed is also very high. The deep groove type continuous uninterrupted raceway of SKF deep groove ball bearing. There is a very good adhesion between the raceway and the steel ball, which can make the bearing bear radial and axial loads in both directions.
4. Spherical roller bearings
Spherical roller bearings are bearings with drum rollers assembled between an inner ring with two raceways and an outer ring with spherical raceways. Spherical roller bearings have two rows of rollers, which mainly bear a load of one diameter, and can also withstand axial loads in either direction. High radial load capacity, especially suitable for work under heavy load or vibration load
