SRT/SSRT series Standardized Rolled Ball Screws with Integrated end-journal For production reason, Rolled Ball Screws are normally necessary to have smaller end-journal, but as KSS has adopted special technology, it enables fixed end-journal bigger than Shaft diameter alike solid Ball Screws. This technology enables stable and more flexible on end-journal design.

SRT/SSRT series（Standardized Rolled & Stainless Rolled Ball Screws with Integrated end-journal）will be supplied with anti-rust oil. This oil is not lubricant, when Ball Screw operates, lubricant should be applied. If there is no specific instruction, KSS would recommend our original Grease（MSG No.2）as standard lubricant. Please feel free to contact us.
●Precision Rolled Ball Screws High accuracy（JIS C5）can be produced by Rolled process, what we call Precision Rolled Ball Screws （PSR/PSRT series） .Please see page -A319.

SRT/SSRT series Standardized Rolled Ball Screws with Integrated end-journal For production reason, Rolled Ball Screws are normally necessary to have smaller end-journal, but as KSS has adopted special technology, it enables fixed end-journal bigger than Shaft diameter alike solid Ball Screws. This technology enables stable and more flexible on end-journal design.

SRT/SSRT series（Standardized Rolled & Stainless Rolled Ball Screws with Integrated end-journal）will be supplied with anti-rust oil. This oil is not lubricant, when Ball Screw operates, lubricant should be applied. If there is no specific instruction, KSS would recommend our original Grease（MSG No.2）as standard lubricant. Please feel free to contact us.
●Precision Rolled Ball Screws High accuracy（JIS C5）can be produced by Rolled process, what we call Precision Rolled Ball Screws （PSR/PSRT series） .Please see page -A319.
