1. The rollers and raceways have line contact or modified line contact, resulting in high radial load capacity, suitable for heavy and impact loads.
2. Low coefficient of friction, suitable for high speeds, with a limiting speed close to that of deep groove ball bearings.
3. N-type and NU-type bearings allow axial movement, accommodating changes in the relative position of the shaft and housing due to thermal expansion or installation errors, and can be used as free-end supports.
4. High precision is required in machining the shaft or housing bore. Strict control must be maintained over the relative misalignment of the outer ring axis after bearing installation to prevent stress concentration.
5. The inner or outer ring can be separable for easy installation and disassembly.
