Comparison Of Ball And Roller Bearings
- Oct 11, 2017 -

Comparison of ball and roller bearings:

From the contact with the raceway: Ball bearings for point contact, contact surface is ellipsoidal, and roller bearings are line contact, when the force, the contact surface is square.

From the characteristics: ball bearings because it is point contact, so the resistance is small, ball bearings suitable for low torque, high speed application conditions. They also have low noise characteristics; roller bearings are more rigid than ball bearings because of their linear contact.

From load capacity: Ball bearing capacity is low but can withstand radial and axial load; the load capacity of roller bearing is higher. Cylindrical roller bearings can withstand a slight axial load on the edge. Double row tapered roller bearings can withstand radial and axial loads.

Tapered roller bearings are mainly subjected to radial and axial joint loads. Bearing capacity depends on the raceway angle of the outer ring, the greater the bearing capacity of the angle. The bearings are separated type bearings and are divided into single row, double row and four row tapered roller bearings According to the number of rolling bodies in the bearing. Single row tapered roller bearing clearance needs to be adjusted by the user at installation; Double row and four row tapered roller bearing clearance has been given in the product at the time of the factory according to user requirements, do not need user adjustment.
