Model and documentation verification Before ordering, the full reference code, revision and application compatibility are checked against manufacturer documentation.
This M33x1.5P variant uses the SWT K-type locking architecture for precision axial retention in CNC spindle and ball-screw support assemblies. Manufacturer family data verifies material, hardness, ISO thread accuracy and run-out. Thread, locking architecture and installation envelope must all match the machine assembly.
An alternative is acceptable only when thread M33x1.5P, locking principle, envelope dimensions, thread precision and run-out requirements are confirmed equivalent. Visual similarity alone is not sufficient.
Technical data on this page is prepared from manufacturer sources and product documentation. Application suitability, safety functions, connection details and revision differences must be confirmed against the exact product code before ordering.
