Rotek Cross-Roller slewing bearings offer increased stiffness and radial capacity. Series 5000 slewing bearings are built with V-groove raceways providing two roller paths in each ring. By alternating adjacent rollers at right angles to one another, one-half of the rollers transmit loads in one direction with the other half transmitting loads in the other direction. The cross roller bearing design provides a higher theoretical dynamic capacity per unit size, greater stiffness, and a lower spring rate than a single roll ball slewing bearing design.
