Q:What are the advantages of using roller bearings in machinery?
A:It has a higher resistance to fatigue and shock than a ball bearing. It Offers simple mounting and dismounting due to its unique design. It is designed to take the combined radial load (N and NU type) and thrust load (NJ and NUP type).

About Bearing:

Roller bearings and ball bearings are two common types of bearings that differ mainly in the following points: The structural design is different: the rolling element inside the roller bearing is a focal point, tapered or tapered roller, while the rolling element inside the roller bearing is a ball. Different bearing capacity: Roller bearings of the same size can withstand larger bearings and bearing loads than roller bearings. The smoothness of rotation is different: the rolling elements inside the roller bearing are longer than that of the roller bearing, so the rotation is smoother at high speeds. The scope of application is different: ball bearings are suitable for small and medium-sized mechanical equipment, while roller bearings are suitable for large mechanical equipment. In short, roller bearings and ball bearings have their own advantages, and in practical applications, it is necessary to choose the appropriate type according to the specific situation.
