The bearing shell is the part in contact between the sliding bearing and the shaft, which is very smooth. It is generally made of wear-resistant materials such as bronze and anti friction alloy. In special cases, it can be made of wood, plastic or rubber.
Here are four things to pay attention to when selecting bearing shells.
1. When the bearing load is large and the speed is low, lubricating grease with small cone penetration should be selected, and vice versa, lubricating grease with large cone penetration should be selected. High speed bearings use lubricating grease with lower cone penetration and good mechanical stability. Special attention should be paid to the lower viscosity of the base oil for lubricating grease.
2. The drop point of the selected lubricating grease is generally 20-30 ℃ higher than the task temperature. In the case of high temperature consecutive tasks, it is important not to exceed the allowed operating temperature range of the lubricating grease.
3. When sliding bearings operate in water or humid environments, calcium based, aluminum based, or lithium based lubricants with good water resistance should be selected.
4. Choose lubricating grease with good adhesion.
