| Its number | VLI200744-N-RL1 |
| Category | Slewing ring, Four Point contact bearing, internal gear teeth |
| Overview | VLI200744-N-RL1-Four point contact bearings, light series 20, internal gear teeth, lip seals on both sides |
| Features and benefits | Slewing rings are generally large size ball or roller bearings with very high load carrying capacity for oscillating motions and slow rotary motions. |
| The bearings are mainly mounted in a horizontal position and are used to support axial forces and large tilting moments. Radial loads only occur to a subordinate extent. The bearing rings are generally screw mounted directly to the immediate parts of the adjacent construction. | |
| The inner or outer ring can be provided with teeth to facilitate drive solutions. | |
| Slewing rings are normally subjected to load while undergoing rotary motion only infrequently, slow swivel motion, slow rotation or while stationary and are mainly dimensioned on the basis of their static load carrying capacity. | |
| Application | Small slewing rings with high precision are also used in robots and robot drives. |
| Slewing rings are normally subjected to load while undergoing rotary motion only infrequently, slow swivel motion, slow rotation or while stationary and are mainly dimensioned on the basis of their static load carrying capacity. | |
