Differences Between Plain Sliding Bearings and Self-Lubricating Bearings
Plain sliding bearings and self-lubricating bearings are two distinct types of bearings used in various applications. Here are the key differences between them:
Plain Sliding Bearings:
- Plain sliding bearings, also known as bushings, are simple bearing components that consist of a cylindrical sleeve made of a bearing material.
- These bearings require external lubrication, such as grease or oil, to reduce friction and wear between the bearing and the shaft.
- Regular maintenance and lubrication are essential to ensure proper operation and longevity.
- Plain sliding bearings are cost-effective and suitable for applications where lubrication can be easily provided.
- They are commonly used in low-speed and low-load applications, where the shaft slides within the bearing.
