THK's New Ultra High-Speed Type SBK Ball Screw with Caged Technology & High Speed Design
Schaumburg, IL (August 26, 2002) - Featuring THK's Caged Technology, the new Type SBK ballscrew offers numerous benefits including ultra high-speed performance, low noise, no piping. It achieves impressive maximum feeds of 120m/min., and a permissible DN value of 160,000.
The utilization of Caged Technology means isolating each of the load carrying re-circulating elements in an individual cage or pocket. This cage prevents ball-to-ball contact and the associated friction. Furthermore, it allows balls to smoothly circulate in a tangential line. The cage also acts as a reservoir for lubricants, eliminating the need for an external
lubricating system. Specific benefits include increased speed and accuracy of motion, decreased noise levels, long-term, maintenance-free operation and reduced sources of contamination.
Long term, maintenance-free operation is enhanced with the optional QZ lubricator. Additionally, the optional wiper ring makes the Type SBK suitable for harsh environments. The wiper ring acts as a barrier to prevent foreign matter and swarf from entering the nut interior.
