Electric Actuator / Compact Series "KSF"

basic information

**Features** 1. Increased Rated Output of Applicable Motors By enlarging the diameter of the ball screw shaft while maintaining a compact outer rail, we have also increased the size of the ball screw terminal. This allows for the use of motors with higher rated output compared to actuators of the same size. Continuous high-speed and high-acceleration operations are now possible, leading to improved takt time. 2. High Speed and High Acceleration The large lead of the ball screw enables a maximum speed of 2000 mm/s. (For KSF8 with a lead of 40) Additionally, by increasing the size of the applicable motors, high-acceleration transport is made possible (up to 2G). 3. Long Stroke By enlarging the diameter of the ball screw shaft, we have achieved a long stroke while maintaining compactness. (Maximum stroke of 1500 mm) ▼ For more details, please refer to the catalog.

Detailed information

• 

  Structure of the Compact Series "KSF" Adoption of large-diameter ball screws enables high speed, high acceleration/deceleration, and long stroke compatibility!

• 

  Increased rated output of applicable motors By increasing the diameter of the ball screw shaft while maintaining a compact outer rail, and by enlarging the end of the ball screw, it has become possible to use motors with higher rated output compared to actuators of the same size. This enables continuous high-speed and high-acceleration operations, leading to improved takt time.

• 

  High speed and high acceleration/deceleration (maximum speed 2000 mm/s, maximum acceleration/deceleration 2G) By increasing the lead of the ball screw, a maximum speed of 2000 mm/s is achieved. (For KSF8 lead 40) Furthermore, by using larger applicable motors, high acceleration/deceleration transport is made possible. (Maximum 2G)

• 

  Long lifespan of 20,000 km By increasing the basic dynamic load ratings of the LM guide section and the ball screw section, we achieved a maximum load capacity while realizing a running lifespan of 20,000 km (for KSF4 and KSF5 with a lead of 10 mm, the running lifespan is 10,000 km).

• 

  Long Stroke (Maximum Stroke 1500mm) By increasing the diameter of the ball screw shaft, we have achieved a long stroke while maintaining a compact design.

• 

  Long-term maintenance-free By standardizing the lubrication device QZ, which enables an appropriate supply of lubricant, we have achieved long-term maintenance-free operation.

• 

  Full Cover Structure "Dust Emission Reduction" The full cover structure is achieved with a strip seal that employs a magnetic adhesion method for the side cover and the top surface. This prevents damage caused by the intrusion of foreign objects from the outside. The top surface of the strip seal has no contact, making it difficult to generate dust. Additionally, assembly and maintenance can be performed simply by attaching and detaching the side cover. *By embedding magnets in the side cover, the strip seal is attracted to prevent it from lifting and reduce the occurrence of gaps.

• 

  Compact and lightweight Compared to actuators using motors with the same rated output, the comparison between KSF4 and VLAST60 achieved approximately 45% compactness and about 11% weight reduction, while the comparison between KSF8 and USW16T achieved approximately 67% compactness and about 37% weight reduction. * KSF4: In the case of a stroke of 700mm * KSF8: In the case of a stroke of 1500mm

• 

  Rich lineup With the addition of KSF5 and KSF8, there are now a total of four models. We have also added a compact motor return specification and a rear tap specification that allows the main unit to be installed without removing the cover, enabling selection according to application. Additionally, since motors from various manufacturers can be installed, customers can use their familiar control methods.
