Rolling touch bearings include: ballbearing; rollerbearing and thrust roller bearing. The advantages of tumbling touch bearings relative to sliding touch bearings are low collision and smoothness; Radial and thrust load; and endurance overload, easy to replace; can maintain appropriate accuracy; can accept preload, launch torque is better than 嫉 嵯蚩 嵯蚩 嵯蚩 . . ..
However, the tumbling touch bearing is more expensive; and it is messy; requires more radial space; has a shorter life span; and is comparable to a sliding touch bearing; its ability to accept a sensation is also poor; even if there is no trace of the notice before the damage is formed Damage to the system; so when choosing a rolling touch bearing or sliding touch bearing, it should be based on its intended use.
