Frequently asked question (FAQ)

Question: What is the main advantage of self-aligning roller bearings?
Answer: Self-aligning roller bearings are advantageous because they can automatically adjust to misalignments between the shaft and housing, making them suitable for applications where shaft deflection or misalignment is common. They can handle both radial loads and axial loads in both directions, with particularly high radial load capacity.
Question: Are self-aligning roller bearings suitable for high-speed applications?
Answer: Self-aligning roller bearings are generally not suitable for high-speed applications. At high speeds, there is a risk of roller slip and smearing, especially under large axial loads.
Question: How should self-aligning roller bearings be lubricated?
Answer: Lubrication for self-aligning roller bearings can be done through oil grooves and holes provided in the bearings. Proper lubrication is essential to ensure optimal performance and longevity.
Question: Can self-aligning roller bearings compensate for misalignment during operation?
Answer: Yes, self-aligning roller bearings can automatically adjust to misalignment and shaft deflections during operation, thanks to their unique design that allows the inner ring, rollers, and cage to tilt freely relative to the outer ring.
Question: What should be considered when installing self-aligning roller bearings?
Answer: During installation, it is important to ensure proper alignment and adequate lubrication of the bearing surfaces. Using a torque wrench for bolt tightening is recommended to avoid shaft slippage and ensure a secure fit.
