What is the difference between rolling bearings and sliding bearings?

[OCora]

Rolling bearings and sliding bearings differ in the following dimensions: 1. Load capacity: Sliding bearings generally have higher load capacity than rolling bearings. 2. Movement method: Rolling bearings operate through rolling motion, while sliding bearings function through sliding motion. 3. Structural aspect: Rolling bearings contain rolling elements that support the rotating shaft through their rotation. Sliding bearings lack rolling elements and instead use smooth surfaces to support the rotating shaft. 4. Friction coefficient: Rolling bearings have lower and more stable friction coefficients compared to sliding bearings. The lubrication of sliding bearings is more susceptible to external factors such as rotational speed and vibration, resulting in a wider range of friction coefficient variation.
