I believe that many people have felt sad about choosing oil-free bushings or linear bearings. In fact, such confusion arises because users do not know enough about oil-free bushings and linear bearings. How should oil-free bushings and linear bearings be selected specifically?
1. In terms of performance, oil-free bushings and linear bearings are very different. Although both can be used with guide shafts, the effects of the two are different.
2. The oil-free bushing is sliding friction, and the linear bearing is the rolling friction of the steel ball device inside, which determines that the resistance of the linear bearing is much smaller than that of the oil-free bushing during the operation.
3. There is also a certain gap in cost between the two. If you choose a linear bearing, the cost is relatively high.
in conclusion.
Obviously, there are certain differences between the oil-free bushing and the linear bearing in terms of performance, structure and cost, which also determines the difference in the actual use effect of the two.
In the choice of the two, we should fully consider the actual use needs, use scenarios and the above factors, so as to ensure that we can choose the high-quality products that suit us to the greatest extent.
