CHOOSE YOUR CONFIGURATION
Same footprint. Two ways to finish it.
SR and SRT share the same diameters, leads and load ratings — the difference is the end-journal. Jump straight to the model range you need.
SR Series
Standard rolled ball screw. Fixed end-journal length, ready to install as-is.
SRT Series
Enlarged fixed-side journal, machined to your spec — end configurations compatible with the SG Series.
Series Overview
Rolled ball screws in Ct7 and Ct10 grades, spanning Ø4 mm to Ø15 mm shafts with leads from 1 mm to 20 mm. Both series ship with unfinished end-journals, so you machine them to suit your design — SR is the standard, cost-effective option, while SRT enlarges the fixed-side journal beyond the shaft diameter for greater design flexibility and end-journal configurations compatible with the SG Series. Stainless steel versions are stocked as the SSR and SSRT series.
Specifications
SR Series model range
34 base models, Ø4–15 mm shafts, 1–20 mm leads. SR ships with a fixed end-journal length, ready to install.
