Ball screw linear module SKR series

single-axiscompact

The Model SKR Caged Ball LM Guide Actuator is a compact actuator that has an inner block consisting of LM blocks and a ball screw nut integrated inside a U-shaped outer rail. In addition, this model achieves high-speed operation, lower noise, and longer-term maintenance-free operation by using ball cages in the LM Guide units and the ball screw unit. (A ball cage is used only for the LM Guide section of Models SKR20 and SKR26, and the ball screws are fitted with QZ Lubricators.) Caged Ball LM Guide Actuator model SKR is a compact actuator that has a inner block consisting of LM blocks and a ball screw nut integrated inside a U-shaped outer rail. In addition, this model achieves high speed operation, lower noise and longer-term maintenance-free operation by using ball cages in the LM Guide units and the Ball Screw unit. (A ball cage is used only for the LM guide section of models SKR20 and SKR26 and the ball screws are fitted with QZ lubricators.) 4-way Equal Load Each row of balls is arranged at a contact angle of 45° so that the rated load on the inner block is uniform under loads applied to the inner block in the four directions (radial, reverse radial and lateral directions). As a result, model SKR can be used in any mounting orientation. High Rigidity Use of an outer rail with a U-shaped cross section increases the rigidity with respect to moment and torsion. High Accuracy Since the linear guide section consists of 4 rows of circular-arc grooves that enable balls to smoothly move even under a preload, a highly rigid guide with no clearance is achieved.
