What is the distinction between crossed roller bearings and ball bearings?
Crossed roller bearings are made to handle multiple loads. The function of one cross roller ring is the same as that of two angular contact ball bearings. Let's look at the differences between roller and ball bearings to find which one is best for you.
Loading capacity of crossed roller vs. ball bearing
Steel balls make up the rolling parts of ball bearings, which are in point contact with the raceway. Crossed roller bearings, on the other hand, have cylindrical rollers that are in line with the raceway. As a result, crossed roller bearings will be able to carry more weight than ball bearings.
Stiffness of crossed roller bearings vs. ball bearings
Crossed roller bearings provide a bigger contact area than ball bearings because the rollers are positioned across on the racetrack. Furthermore, the clearance of cross roller rings can be set to a negative value. As a result, the stiffness of cross roller rings is 3~4 times that of ball bearings.
Clearance and precision
Yogie uses high-precision cylindrical rollers as bearing rolling components, and the raceways of bearing rings are super-ground, resulting in remarkable accuracy for Yogie crossed roller bearings. Because bearing clearance may be altered, negative clearance improves cross roller ring running accuracy and stiffness.
Starting torque
Because the beginning torque of crossed roller bearings is larger than that of ball bearings, their rotation will be "tighter," not as flexible. Cross roller rings, on the other hand, may maintain great precision even after repeated operations.
Mounting
Cross roller rings offer greater mounting area and mounting technique options than ball bearings. They may be placed in a little amount of space, and certain varieties can be directly linked to the equipment.
Applications, costs, and service life are all factors to consider.
Crossed roller bearings are more expensive than ball bearings due to their manufacturing technique. Users must make their selections depending on the applications. Cross roller bearings, for example, are better suited if larger loading capacity is required. If you need flexible rotation and have a restricted budget, ball bearings are an option.
