XK KR series curve wheel track roller bearing
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.
KR series (with eccentric sleeve model KRE)
KR series of curve roller bearings for the needle roller cage assembly bearings, the outer ring through the bolt on the flange and fixed on the bolt on the axle was guided, can withstand heavier load and the speed. As the bearing has more grease inside the space, so the lubrication cycle can be extended.
