SG Series
High accuracy, high rigidity ballscrew actuator
Ideal for high-precision positioning
KURODA ballscrew actuators are compact, single-axis units consisting of a ball screw and a linear guide rail. By designing the slide block to fit within a U-shaped guide rail, the actuators achieve a compact, low-profile design when compared with conventional ball screw installations.
The SG series deliver excellent accuracy and rigidity, making them especially suitable for precision positioning.
MENU
Space-saving
Integration of the slide block into the profile of the U-guide rail reduces the dimensions when compared to conventional ball screw installations.
Precise
All threads within the actuator use a 4 point contact Gothic arch stucture to assure maximum rigidity. The guide rail, slide block, and ball screw shaft are manufactured using our industry-leading techniques, making precise positioning possible.
Rigid
Using a single piece of steel in the U-shaped guide rail provides optimal rigidity that even allows for configurations in which the actuator is only supported at one end. Short block, long block, and second block design iterations are available to enhance permissible moment specs.
Easy to install
This integrated unit eliminates the need for complicated, fine adjustment that would otherwise be needed to achieve shaft center alignment and synchronized operation.
Dustproof cover
A top cover to prevent contaminant penetration and ensure safety.
Dustproof bellows
Dustproof bellows for protection against environmental conditions.
Various motor brackets, intermediate flanges, and parallel motor mounting brackets
Motor brackets and intermediate flanges to mount various types of motors are available. Brackets for parallel mounting and parallel pulley units are also available to reduce the necessary footprint.
Surface treatment
Anti-corrosive black coating with high dustproof performance is available.
Dust-preventive grease (S grease specifications)
Dust-preventive grease “KURODA S grease” can be applied to ball screws and guides to suppress dust generation from the grease. For information on other greases, please contact us.
Sensor
Sensor rail mounting holes are provided at both sides of a guide rail so that a sensor can be mounted on either side.
