Caged Ball
LM Guide Actuator
SKR |
The SKR-type LM guide actuator with Caged Ball Technology is an actuator that features an LM rail having a U-shaped cross section, a one-piece nut block structure with LM guide raceways on both sides, and a ball screw at the center. This enables the actuator to provide highly rigid and accurate functioning at a minimum size. Each train of balls is arranged at a contact angle of 45o so that the rated load on the nut block is uniform in four directions (radial, reverse-radial, and lateral directions). As a result, the SKR-type LM guide actuator can be used in any mounting orientation. Moreover, the addition of the LM guide and ball screw with Caged Ball Technology allows the SKR-type LM guide actuator to achieve higher speeds, lower noise, longer maintenance-free operation, and other features in comparison with the conventional KR-type.
