The SL 4R-2T feed unit (4-rolls wire feeder, 2 rolls drive in the price list) is the wire drive mechanism with four rolls, two of them driven. According to the selection guide of the Böhler 2026/27 price list it is factory fitted in WF NX 330 Smart and WF NX 430 Smart feeders and in the TERRA NX 320/400 SMC Smart.
What it is for
Replace the whole unit when the mechanism is damaged, not just the rolls or a single gear; small drive parts (rolls, gears, bearing, knobs, washers) are available separately. The price list does not say whether rolls are included, so confirm the content with us before ordering. A 2T drive can be upgraded to four driven rolls with kit 07.01.512.
