What is the difference between a sliding bearing and a bearing bush? Under what circumstances are sliding bearings used, and under what circumstances are rolling bearings used?
The biggest difference between rolling bearings and sliding bearings is that rolling bearings involve rolling friction； Sliding bearings experience sliding friction. Sliding bearings are generally suitable for applications with heavy loads
Sliding bearings are typically used in equipment with high shaft power, high rotational speeds, or heavy rotors.
Reply to 1# Naoniu Loves the Internet: Sliding bearings consist of bushings and bearing shells, both of which fall under the sliding bearing category. The difference between bearing shells is that they are in a semi-circular shape, while other sliding bearings are generally round in shape.
Reply 2# hxlhb: Shouldn’t rolling friction be used in situations with high loads? Because rolling friction is slightly less than sliding friction
Split sliding bearing (bearing shell), a sliding bearing that operates under sliding friction. Sliding bearing applications are generally in low-speed, high-load operating conditions. Bearing shells are divided into split-type and integral-type structures.
Sliding bearings are generally used in situations where high power is required, the rotor has a large weight, and friction is high. The lubrication method for sliding bearings is always oil circulation lubrication, which helps to maintain a suitable temperature of the bearings
Reply to 5# Twelve-stroke point contact stress. . . . . . . . . . . . You understand
Sliding bearings are used for low-speed, heavy-load applications.
Generally, a bearing bush refers to a sliding bearing; rolling bearings involve line or point contact, while sliding bearings involve surface contact, and they can bear larger loads.
I agree with the view above; a sliding bearing generally refers to a bearing shell, and it can only withstand forces in one direction.
