SRT / SSRT Flanged Nut Large Journal

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 ABSSAC have 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.

Features

Design flexibility and wide use of Bearings on end-journal.
Compatible end-journal to Precision Ball Screws.
No need to insert or press fit collar as Bearing shoulder.
Quick delivery due to unfinished end-journal stock.
Stainless Rolled Ball Screws are also available.

Accuracy Grade & Axial play

The grade of SRT/SSRT series (Standardized Rolled & Stainless Rolled Ball Screws with Integrated endjournal) are Ct7 or Ct10(JIS B-1192). According to accuracy grade, Axial play 0.020mm or less (Ct7) and 0.050mm or less (Ct10) are in stock.

Material & Surface hardness

Materials and Surface hardness of SR series (Standardized Rolled Ball Screws) and SSR series (Standardized Stainless Rolled Ball Screws) are as follows.

Products	Material of thread area	Heat treatment	Surface hardness
Rolled Ball Screws (SRT series)	Shaft : SCM415	Carburizing and Quenching	HRC58 or more
Rolled Ball Screws (SRT series)	Nut : SCM415	Carburizing and Quenching	HRC58 or more
Stainless Rolled Ball Screws (SSRT series)	Shaft : SUS440C	Induction hardening	HRC55 or more
Stainless Rolled Ball Screws (SSRT series)	Nut : SUS440C	Vacuum hardening	HRC55 or more

Lubrication

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, ABSSAC would recommend our original Grease (MSG No.2) as standard lubricant. Please feel free to contact us.
