Frequently Asked Questions
What are rolling centers used for?
Rolling centers, or live centers, are mounted on the tailstock of a lathe to support the free end of a workpiece. They rotate with the workpiece, reducing friction and preventing deflection during turning, facing, or drilling operations.
Are these centers compatible with all lathes?
These centers have standard Morse taper shanks (MT2, MT3, MT4) for mounting into the tailstock or headstock spindle. Most lathes accept one of these tapers, but you should verify your machine's spindle taper size before ordering.
Can I replace the tips on these rolling centers?
Yes, the tips are interchangeable. The set includes both a standard 60° point and a smaller point for different workpiece profiles. Replacement tips can be ordered separately.
Are these suitable for heavy marine machining?
Absolutely. The hardened alloy steel body and precision bearings provide the strength and rigidity needed for marine shaft repairs, propeller machining, and other heavy-duty applications.
