Adjusting Nut WJ070027/133 BFT Water Jet Parts

The BFT Adjusting Nut WJ070027/133 is a precision-machined component used in BFT Abrasive Waterjet cutting heads—particularly the 3D tilting head assemblies—to fine-tune the compression and alignment of the Mixing Chamber and Focusing Tube. Manufactured from hardened stainless sTeel (or anodized aluminum in some OEM variants), this nut interfaces with the cutting-head housing via fine threads, providing micrometer-scale adjustment of the jet focus position. Proper use of the WJ070027/133 ensures optimal cutting accuracy, uniform kerf width, and extended life of wear parts (Orifice, mixing chamber, focusing tube). Below is a detailed overview of its features, specifications, installation, and sourcing.
