The SL 4R-4T feed unit (4-roll wire feeder, 4 rolls drive in the price list) is the wire drive mechanism with four driven rolls. According to the Böhler 2026/27 price list it works in WF NX 330 and 430 SteelDrive, WF NX 330 DualFeeder and WF NX 4000 Smart feeders and in machines with built-in feeder: TERRA NX 320/400 SMC and PMC SteelDrive, TERRA NX 400 PMC DualFeeder, URANOS NX 2200 and 2700 PMC and MTE.
What it is for
Replace the whole unit when the mechanism is damaged, not just the rolls or a gear; small SL 4R drive parts are available separately. In the price list selection guide SL 4R-4T is also an option for WF NX 330/430 Smart and TERRA NX 320/400 SMC Smart. The price list does not say whether rolls are included, so we confirm the content before ordering.

FAQ
I have a Smart feeder. Replace the unit or buy the upgrade kit?
For WF NX 330 Smart and WF NX 430 Smart the price list gives upgrade kit 07.01.512 (from 2 to 4 driven rolls, 1.0/1.2 mm wire). The complete SL 4R-4T unit makes sense when the mechanism itself is damaged.
Does it fit URANOS 2000 SMC?
No. URANOS 2000 SMC has the two-roll SF 2R-1T feed unit (07.01.324).
