2Pcs Roll Wheels Knurled Groove Wire Feed Drive Rollers 25mm (1 inch) Diameter, Aluminum Oxide Medium Grit, Fit for SSJ16 Wire Feeder MAG MIG Welders Equipment Parts (0.8/1.0mm)

My mig wasn't advancing the wire properly, these worked perfectly

A knurled wire feeder wheel just makes sense and works better than the smooth wheel my welder came with. Cheap and easy, no issues now with wire not feeding smoothly start to finish. Don't overtime it, just get it. You're welcome.

does not fit the campbell hausfeld mig flux 105 wire feeder.. they are to small around or tall.. mine requires a 30 mm tall wheel.. parts are what they say so no complaint i just wasnt sure what size i needed until i had recieved them and saw the one on my welder was larger than this one.. seem to be made of good quality just not what i needed

My HF welder was slipping the wire feed making for inconsistent welds. This was a perfect upgrade for very little money. Highly recommended!

This roller is not knurled and packaging was labeled that it was, so take your chances... Does NOT work for the older blue Chicago Electric 90 Amp welder as the roller groove is higher than the wire tracking..
