Buying Guide

Match screw profile and diameter

Choose between SFU and RM profiles and verify the 16 mm shaft diameter to ensure compatibility with existing pillow blocks, couplings, and lead screws

Check lead and travel requirements

Confirm the screw lead (commonly 5 mm on SFU1605/RM1605) and available lengths (250–1050 mm in this list) to meet desired linear travel and resolution

Verify end supports and mounts

Look for included BK/BF12 or similar end bearings and housings so the screw can be mounted without extra adapter machining

Consider nut type and backlash

Select a ball nut or anti-backlash nut when repeatable positioning is required; some kits include preloaded or anti-backlash nuts for tighter control
