KORRETTO · Lathe center series
Light-Duty Live Center
Light-duty live centers are used for small and light workpieces that require stable rotating support from the tailstock. They are suitable for light turning operations, compact shaft-type parts and general lathe support applications.
Send the Morse taper, workpiece weight, center hole size, machining speed and support requirement, and we will help check whether this light-duty live center series fits your setup.
Product Overview
The KORRETTO light-duty live center is designed for light turning and small shaft support applications. It provides rotating tailstock support for workpieces that do not require medium or heavy load capacity.
How a Light-Duty Live Center Works
The Morse-taper shank locates the center body in the tailstock, while the internal bearings allow the spindle and point to rotate with a small workpiece. The point supports the workpiece at its center hole and transfers tailstock thrust and machining reaction into the bearing assembly. The light-duty format is intended for lower support loads; stable operation still depends on taper fit, center-hole quality, workpiece weight, cutting force, tailstock pressure and RPM.
Typical Applications
- Light turning operations
- Small shaft-type workpieces
- Tailstock support on lathes
- Compact workpieces with moderate support requirements
- Applications requiring MT3 or MT4 live center support

Selection Notes
Before selecting a light-duty live center, confirm the Morse taper, workpiece weight, center hole size, machining speed and support load. This series is suitable for light turning and small workpieces, not for heavy shaft machining.
When a Light-Duty Live Center Is Not Suitable
Do not use this series when the workpiece weight, RPM or cutting load exceeds the selected model's table value, or when long overhang and interrupted cutting create higher support reactions than a light-duty center can carry. It is also unsuitable with a mismatched taper or defective center hole. Medium-duty, heavy-duty or high-speed designs should be evaluated when load, shaft size, coolant exposure or operating speed falls outside the light-duty range.
FAQ
What is a light-duty live center used for?
A light-duty live center is used for rotating tailstock support of smaller and lighter workpieces. It is suitable for general turning work where support load is relatively low and stable rotating support is needed.
Is it a live center or a dead center?
It is a live center. The center rotates with the workpiece and is selected for general-purpose tailstock support under lighter working conditions.
What machine taper should be confirmed?
Please confirm the tailstock taper or machine center interface before selection. The light-duty live center must match the machine taper correctly.
What workpiece weight or support condition should be checked?
Please confirm the workpiece weight, shaft length, center-hole size and support load. These factors determine whether a light-duty center is sufficient for the process.
What speed or load should be considered?
Please confirm the operating speed and support load. The center should be selected according to the real machining duty and not only by taper size.
How is it different from medium-duty or heavy-duty live centers?
A light-duty live center is selected for smaller workpieces and lower support loads. Medium-duty and heavy-duty models are used when the workpiece is larger or the support load is higher.
What should be checked before installation?
Check the taper fit, center-hole condition, workpiece alignment and operating speed before installation. The contact surfaces should be clean and properly matched.
What information is needed for quotation?
Please provide the machine taper, workpiece weight, shaft length, center-hole size, speed range and machining process.
