It is a trapezoidal screw made of S45C material. Shaft end processing is also possible.
We can also manufacture items that require processing. Right-hand threads are of type YTr-R, and left-hand threads are of type YTr-L. The nuts are available in both flanged and straight versions made of BC6 material.
Uses special alloys! Bearings with minimal variation in precision, high accuracy, and excellent wear resistance.
The "Screw Nut" DCM type/DC type is manufactured according to the standards of 30-degree trapezoidal threads. The nut is made from a special alloy and is die-cast molded using a precision male thread as a core. As a result, unlike machined products, it has less variation in precision and is a high-precision bearing with excellent wear resistance. The screw shafts that are combined are standardized through forming. Additionally, we also manufacture cutting screw shafts and grinding screw shafts according to your application, so please feel free to inquire. 【Features】 ■ Manufactured according to the standards of 30-degree trapezoidal threads ■ Made from a special alloy ■ Less variation in precision, high precision, and excellent wear resistance *For more details, please refer to the PDF materials or feel free to contact us.
This is a compact precision ball screw with a ball retainer from THK that adopts a tangent direction scoop. It enables high-speed and compact equipment.
A new technology has been adopted that realizes an ideal ball circulation structure in the ball screw nut, enabling smoother rotational motion. The use of a ball retainer has achieved a maximum rotational speed of 5,000 min-1 (DN value: 160,000 MAX). The outer diameter ratio of the nut has been reduced by up to 30%. The dimensions of the nut comply with DIN standards [DIN69051-5]. *As of September 2021, the lineup of SDAN-V shapes has been expanded.
The new ball circulation system achieves a maximum high-speed performance with a DN value of 170,000 and a full ball type, while also realizing a higher load capacity.
- High-speed performance The newly developed circulation structure significantly improves the DN value. A large lead is adopted to meet the demands for high-speed performance. - Design that meets the performance requirements of machine tools Groove design that achieves increased load capacity. BSM realizes improved load capacity through its unique groove design and two-row groove structure. - Compact and high rigidity Compared to conventional products, the nut outer diameter is compact while achieving high rigidity. BSM-B contributes to space-saving design by slimming down the nut outer diameter compared to our conventional products.
The coolant circulates evenly inside the nut, effectively cooling both the shaft and the nut, as well as the ball screw!
It is possible to simplify the cooling of ball screws, which is effective for increasing the speed of machine tools. Cooling is achieved by circulating coolant inside the nut. By simply piping to the outer circumference of the nut flange, a cooling effect equivalent to that of a hollow shaft ball screw can be obtained. By optimizing the cooling structure inside the nut, the temperature rise of the screw shaft is kept equivalent to that of core cooling. By combining the cooling mechanism with a single nut and a high-rigidity double nut system, thermal expansion is suppressed, enabling stable heavy cutting. *For more details, please refer to the catalog PDF.
It is a stainless steel trapezoidal screw. Shaft end machining is also possible.
Uses SUS304 austenitic stainless steel. Can also be manufactured for items requiring machining, such as shaft ends. Right-hand threads are standard. Nuts are available in both flanged and straight versions made of BC6 material.
A sliding screw change nut suitable for creating a fast-forward mechanism with low-speed rotation due to the large lead.
The "Change Nut" DCMA type/DCMB type is a change nut with a lead angle of 45° that is not easily obtained through machining. It can convert linear motion to rotary motion and rotary motion to linear motion with high efficiency, and due to its large lead, it is suitable for creating a fast feed mechanism at low rotational speeds. The multi-thread screw shaft CT that combines with the "Change Nut" is formed by cold rolling. The surface hardness of the tooth profile is processed to over 250HV, and it is also mirror-finished, resulting in extremely smooth movement when combined with the "Change Nut" and excellent wear resistance. 【Features】 - High efficiency conversion of linear motion to rotary motion and rotary motion to linear motion - Suitable for creating a fast feed mechanism at low rotational speeds due to its large lead *For more details, please refer to the PDF document or feel free to contact us.
With semi-custom orders and short delivery times, we can streamline the work processes at each stage. The new screw shaft diameter φ10 SDA10VZ has also joined the lineup.
Customizable semi-order with a short delivery time of just 10 days. This is a precision ball screw with a compact nut shape compliant with ISO/DIN/JIS standards, suitable for global use. It features smooth rotation without gaps and high precision in positioning, making it particularly ideal for positioning and transport sections of FA automation machines. Newly added are three items with screw shaft diameters of φ10, and ball screw leads of 4mm, 5mm, and 10mm, expanding the SDA-V lineup to a total of 62 items, combining screw shaft diameters from φ10 to 50 and leads from 4 to 50mm. Stroke in 1mm increments + screw shaft end shape + support unit. You can specify/select according to your requirements.
The adoption of the double nut method has doubled the load capacity compared to the conventional single nut method. It supports longer lifespan and higher speeds.
This is a ball screw with a double nut preloading method that includes a ball retainer. The SBKN type features an ideal ball circulation structure and the adoption of a ball retainer, providing excellent high-speed performance and load durability. - Achieves approximately twice the basic dynamic load rating and about six times the lifespan. - DN value of 160,000, compatible with high-speed drive. Low noise and long-term maintenance-free. For more details, please refer to the catalog or feel free to contact us.
"Hollow Ball Screw N Series" capable of forced cooling of the ball screw shaft.
It is a hollow ball screw capable of forced cooling that contributes to the high precision of machines. It is not a special series, but an additional model of standardized existing ball screws. The maximum shaft length is 3000mm (φ25/φ32).
