Curved roller bearings can withstand heavier radial loads, and since the outer ring is axially guided by the rollers, the bearings can also withstand heavier axial loads, allowing for relatively high-speed operation. However, since it is a full complement roller, it is often necessary to fill the lubricant at both ends of the mandrel or the hole in the mandrel body.
KRV series (with eccentric sleeve model KRVE)
KRV series curve roller bearings are full complement needle roller bearings. The outer ring is axially guided by the ribs on the bolts and the retaining rings fixed on the bolts. It can bear heavier load and lower speed, but need to be lubricated frequently fat.
