FAQs About Plain Bearings
Q: What is the difference between sleeve and flanged bearings?
A: Sleeve bearings have a cylindrical shape, while flanged bearings have a flange on one end to prevent axial movement.
Q: How do plain bearings handle misalignment?
A: Plain bearings can accommodate misalignment due to their conforming surfaces. However, excessive misalignment can reduce bearing life.
Q: What are the factors that affect the lifespan of plain bearings?
A: Load, speed, lubrication, temperature, and surface treatment all impact the lifespan of plain bearings. Proper maintenance can extend their service life.
