Execution guidance
Precision design and inspection
Design function
The precision family uses a controlled radial outside diameter for tighter guide accuracy.
Installation and adjustment
Do not replace it with a standard-OD version without confirming profile clearance and the controlled drawing.
Inspection focus
Record radial OD, runout, axial position and the specified precision class.
Application
Application and RFQ checklist
Precision mast guides, steel sections and plate-mounted lift assemblies.
