The circulation structure feature allows the balls to be picked up tangential to the direction of movement. The circulation components have been strengthened, increasing the DN value to 160,000 (small type: 130,000).
A return-pipe type Ball Screw that has a circulation structure where balls are picked up in the tangential direction and is provided with a strengthened circulation path, thus to achieve a DN value of 130,000.
With this Ball Screw, a compact structure is achieved as a result of adopting the offset preloading method, which shifts two rows of grooves of the ball screw nut.
As a result of adopting the offset preloading method, which shifts two rows of grooves of the ball screw nut, a compact structure is achieved.
A ball screw with newly developed circulation components that give it an ideal ball circulation structure. (Maximum DN value: 160,000)The nut dimensions conform to DIN standards (DIN69051). Furthermore, the use of the newly developed thin film seal reduces the length of the nut, achieving a more compact design for the device. This is the full-ball type version of the Model SDA-V. (Maximum DN value: 130,000)
With the optimal design for high loads, this Ball Screw model achieves a rated load more than twice the conventional type.
Model SBKH is a ball screw that achieves a high load carrying capacity and is capable of highspeed operation (92 m/min at a maximum).
The right and the left screws are provided with a phase in the middle of the ball screw nut, and an axial clearance is set at a below-zero value (under a preload). This compact model is capable of a smooth motion.
A deflector-type Ball Screw in which the right and left screws are provided with a phase in the middle of the ball screw nut, and an axial clearance is set at a below-zero value (under a preload).
A nut-rotating Ball Screw in which a defector-type ball screw nut is integrated with a support bearing.
The most common type with a preload provided via a spacer between the two combined ball screw nuts to eliminate the backlash. It can be mounted using the bolt holes drilled on the fl ange.
The most common type with a preload provided via a spacer between the two combined ball screw nuts to eliminate backlash.
A deflector-type Ball Screw in which a preload is provided via a spacer between the two combined ball screw nuts to achieve a below-zero axial clearance (under a preload).
Since a preload is provided through a spacer between two large lead nuts, this Ball Screw model is capable of high-speed feed without backlash.
The simplest type with a single ball screw nut. It is designed to be mounted using the bolt holes drilled on the fl ange.
Since mounting screw holes are drilled on the square ball screw nut, this model can compactly be mounted on the machine without a housing.
The most compact Ball Screw with the outer diameter of its ball screw nut being 70 to 80% of that of the return-pipe type.
A miniature type with a screw shaft diameter of φ4 to φ14 mm and a lead of 1 to 5mm.
This Ball Screw for high-speed feed achieves a DN value of 120,000 by using a new circulation structure.
With this Ball Screw, the lead length is 1.5 to 3 times greater than the shaft diameter.
A nut-rotating ball screw that has an integrated structure consisting of a ball screw nut and a support bearing.
This Ball Screw achieves zero-backlash through a constant preloading method by shifting the phase with the central part of a simple nut as the spring structure.
A compact, round type Ball Screw with a ball screw nut incorporated with a return pipe. The flange circumference is cut flat at the top and bottom, allowing the shaft center to be positioned low.
A miniature type with a screw shaft diameter of φ6 to φ12 mm and a lead of 1 to 2 mm.
Since mounting screw holes are drilled on the square ball screw nut, this model can compactly be mounted on the machine without a housing.
Using an end-cap method, these models achieve stable motion in high-speed rotation.
With a combination of 4 rows of large-lead loaded grooves and a long nut, this Ball Screw achieves a long service life.
A nut-rotating ball screw that has an integrated structure consisting of a ball screw nut and a support bearing.
With this Ball Screw, the right and left screws are provided with a phase in the middle of the ball screw nut to achieve a below-zero axial clearance (under a preload).
A miniature type with a screw shaft diameter of Φ4 to Φ14 mm and a lead of 1 to 5mm.
A miniature type with a screw shaft diameter of Φ4 to Φ14 mm and a lead of 1 to 4mm.
