Special ball screw: according to the different mechanical and operating conditions, NSK gave a targeted solution.
1 .HMD series: It is used for high speed machine tools. Using a special cycle design, it can achieve Dn value of 160 thousand.
2 .HMC series: It is used for high speed machine tools. Using a special ball cycle design to strengthen the strength of the cycle, it can achieve high speed performance of 40~120m/min.
3 .BSL series: It is used for small lathe and uses the cycle of the diversion end, which achieces the D.n value of 180 thousand.
4 .HTF series: It is used for large load drive and is applied in machinery like injection molding machines and so on. The special raceway and circulation design are adopted to realize high speed, high torque and high mute effect.
5. VSS series: It is high speed design BSS type high seal type. It has Specific BSS series high speed, mute effect. Due to the installation of the V1 series with high dust sealing device (NSK patent), this achieves an unparalleled sealing effect and achieves the ultra long service life in the high dust environment.
6. TW series: It uses dual screw drive. Special processing ensures that the various parameters of the two lead screws are nearly the same, achieving that the common double screw drive can not be compared with the synchronization performance.
7. Hollow screw: In order to reduce the influence of temperature rise on the precision of the screw, a hollow cooling screw is developed. It realizes the advantages of short preheating time and stable precision.
8. Sigma series: It is used for machine hand. Single screw achieves the role of transmission and steering. Screw shaft end not only can be telescopic but also can achieve rotation.
9. Handling machinery: This is low precision, low price and large lead design, which is suitable for high speed transmission. Customers can independently handle the shaft end size.
Standard stock ball screw series:
According to the usage of the various industry, the standard size series is introduced, which is suitable for general small machinery and automation equipment.
1. Small FA PSS series
2. MA series for miniature lead
3. FA series for small machines
4. SA series for working machines
5. KA series for stainless steel products
6. MS, FS and SS series for axis end unprogressed
Standard screw shaft end support unit WBK series is available for selection.
Special ball screw with standard nut:
The nut size of the series is all the Japanese JIS standard. the nut is classified in accordance with the rolling cycle. Shaft end is processed on
base of customer specific requirements.
According to the way of rolling cycle, the nut is divided into:
BSS series for the end of the diversion loop: It is suitable for occasion of high
speed applications.
Tubes cycle series: Nut types include: SFT, DFT, ZFT, PFT and LSFT, LPFT, LDFT with large lead. GSCT has not flange type.
An inner cycle series: It has MSFD,MPFD types with big lead and the common SFD, ZFD, DFD types. Compared with tube circulating type, the overall size is reduced and more compact.
An end cover cycle series: With ultra large lead design, LSFC, LPFC, USFC and UPFC can achieve high-speed feed.
The ball screw is an ideal product for converting rotary motion into linear motion, or converting linear motion into rotary motion. The ball screw is composed of a screw, a nut and a ball. Its function is to convert the rotary motion into linear motion, which is the further extension and development of the ball screw. The significance of this development is to move the bearing from the rolling action to the sliding action. Due to the small friction resistance, ball screw is widely used in various industrial equipment and precision instruments.
