Product Description
The SFK0401 is a miniature rolled ball screw assembly consisting of a 4 mm screw shaft and matching recirculating ball nut. Its 1 mm lead provides controlled linear travel in compact mechanisms where installation space is limited.
Rolling elements circulate between the screw and nut to reduce sliding friction and improve transmission efficiency compared with a conventional sliding lead screw. Proper alignment, end support, lubrication, and protection from contamination are required for reliable operation.
Required screw length, end machining, mounting arrangement, accuracy grade, and nut dimensions should be confirmed before ordering.
We build to customer drawings under OEM/ODM, and accept orders as small as a single piece for standard sizes.
