Frequently Asked Questions
Do the listed reference numbers describe the same T223 guide bush family?
They are commonly used as cross-references for the same general dimensional family. Confirm the outside diameters, length, thread, A° and machine application before ordering.
Is the nominal bar diameter enough to specify the guide bore?
No. The actual bar diameter, tolerance, straightness, surface condition and material all affect the required running clearance.
Can T223 guide bushes be produced with hexagon or square bores?
Yes. PRONIXT reference capacities are Ø20.5 round, 17 AF hexagon and 14 AF square. Other profiles can be evaluated from a drawing or sample.
