NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President and CEO: Norio Otsuka) announced that it will launch a new mid-size high-speed SS series ball screw and support unit for high-speed and heavy-load in February 2013. NSK is targeting one billion yen in sales for these products by 2015. NSK will display them at the 26th Japan International Machine Tool Fair (JIMTOF 2012), to be held from Thursday, November 1 to Tuesday, November 6 at Tokyo Big Sight (Koto ward, Tokyo).
Development background
In recent years, the demand for ball screws that feature higher speeds has increased along with the need for higher levels of productivity in machining tools and dedicated processing machines for such applications as automobile manufacturing equipment. Not only have the demands for higher speed increased, but also has the insistence on quicker delivery.
In order to meet the demand for higher speeds, NSK has utilized its proprietary high-speed, silent operation technology to develop the high-speed SS series as well as the midsize support unit that is compatible with high-speed and heavy load operations. Both of these products will be standard inventory, ensuring quick delivery.
Product features
1. High-speed ball screw, low heat generation support unit
Utilizing the strength of its proprietary high-speed and silent operation technology, NSK has been able to achieve a smooth ball circulation. This makes it possible to more than double the dn*1 allowance of conventional tube circulation methods for a high speed of 160,000, allowing for a maximum feed speed of 80 m/min.*2 In order to reduce the heat generated by the support bearing due to the increased speeds, NSK uses a low precompression type bearing in the support unit, which makes it possible to reduce the generated heat by as much as half.
*1. Shaft diameter d (mm) x rotational speed n (min-1)
*2. With a shaft diameter of 40 mm and a lead of 20 mm
2. Silent, low-vibration ball screw
The new circulation method NSK developed, utilizing the strength of its proprietary high-speed, silent operation technology, also reduces noise by up to 6 dBs (A) and reduces vibration levels to a maximum of one-half of that of the conventional tube type.
3. Quick delivery of the ball screw and support unit
The high-speed SS series ball screw and accommodating midsize, support unit for high-speed and heavy-load are both standard inventory parts, allowing for quick delivery.
4. Bountiful variation
NSK has put together a wide-ranging lineup of 33 ball screw variations and 10 support unit variations suited to machining tools and dedicated processing machines. In addition, the shaft end shape can be easily modified during post-processing for customized specifications.
