Many people don’t know the ball bearing and roller bearing difference

Many newcomers do not understand what is the bearing deep groove ball bearing, what is the tapered roller bearing, what is the ball bearing and roller bearing difference, ball bearing and roller bearing difference of using.

In fact, from the appearance is enough to distinguish ball bearing and roller bearing difference

1, the appearance of ball bearing and roller bearing difference: deep groove ball bearings (see the figure below), its rolling body is spherical, the inner and outer rings are not separable. This kind of bearing is the most common kind of bearing. The code starts with 6 characters and is divided into closed and non-closed, and there is a distinction between iron cover and plastic cover.--ball bearing and roller bearing difference

ball bearing and roller bearing difference--Tapered roller bearings (see the figure below), its rolling elements are conical, the inner and outer rings are separable. The code starts with 3 characters and also has some variants.

2, ball bearing and roller bearing difference of using: deep groove ball bearings: deep groove ball bearings mainly bear radial load, but also can bear radial load and axial load. When it is only subjected to 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 withstand a large axial load. The deep groove ball bearing has a small friction coefficient and a high limit speed. Not resistant to impact, not suitable for heavy loads, used in gearboxes, instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yo,etc.

ball bearing and roller bearing difference--tapered roller bearings : This kind of bearing has low speed limit and is used in industries such as automobile, rolling mill, mining, metallurgy and plastic machinery. Simply speaking, deep groove ball bearings are suitable for high speed and low load applications and can withstand radial loads and certain axial loads. Tapered roller bearings are suitable for low speed and high load applications and can withstand both radial and axial loads.
