KORRETTO · Lathe center series
Super Load Live Center (10–15T)
Super load live centers are designed for ultra-heavy workpieces requiring 10–15T support capacity. They are suitable for oversized shafts and extreme turning conditions where standard high load live centers are not sufficient.
Send the machine type, workpiece weight, shaft diameter, support load, structure requirement and center hole condition, and we will help check whether this super load live center series fits your setup.
Product Overview
The C111 super load live center is for large shafts and workpieces in the 10–15T range listed below. The table separates MT6, HS80 and HS100 mounting structures. Each model has its own workpiece-weight and speed values.
How a Super Load Live Center Works
The machine-side taper or specified mounting structure supports a stationary center body, while a large bearing-supported spindle rotates with the workpiece. Tailstock thrust and the machining reaction from an oversized shaft pass through the workpiece center hole into the spindle and bearing assembly. In a 10–15T support application, the complete load path matters: machine and tailstock capacity, center-hole geometry, axial thrust, radial cutting load, workpiece balance and speed must all be checked together.
Typical Applications
- 10–15T ultra-heavy workpiece support
- Oversized shaft turning
- Heavy lathe machining
- Large workpieces requiring extreme rotating support
- Applications requiring MT6 / HS80 / HS100 type structures

Selection Notes
Match the machine interface first. C111010 uses MT6, C111110 uses HS80, and C111210 uses HS100. Compare the drawing with the tailstock interface and the available space around the workpiece end.
Read capacity and speed from the same model row. C111010 lists 10,000 kg and 1000 rpm. C111210 lists 15,000 kg and 500 rpm. Do not use the higher weight from one row with the higher speed from another.
The load passes from the workpiece center hole through the center spindle and bearings into the tailstock. Check the tailstock capacity, center-hole condition and workpiece balance as part of the setup. For the lower 3–5T range, see the high load live center.
When a Super Load Live Center Is Not Suitable
Do not select a super load center from workpiece weight alone. It is unsuitable if the tailstock, mounting taper, extraction arrangement or machine structure cannot safely carry the combined load, or if the center hole and support geometry are not designed for that load. The 10–15T class does not by itself guarantee high-speed or precision-grinding performance. Final selection should be checked against the actual RPM, cutting forces, thermal expansion, balance and machine manufacturer's limits.
FAQ
What is a super load live center used for?
A super load live center is used for rotating tailstock support of very heavy workpieces and long shafts. It is selected when the support load is beyond the normal heavy-duty range and a stronger center structure is required.
Is it a live center or a dead center?
It is a live center. The center rotates with the workpiece and is selected for very high load support applications under rotating conditions.
What machine taper should be confirmed?
Please confirm the tailstock taper or machine interface before selection. The super load 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 the 10–15T class is suitable for the application.
What speed or load should be considered?
Please confirm the operating speed, tailstock support load and radial working condition. Final selection should be based on the real load and not only the workpiece diameter.
How is it different from a heavy-duty or high load live center?
A super load live center is intended for even higher support duty and larger workpiece conditions. It should be selected only when the machine, workpiece and support load justify this load class.
What should be checked before installation?
Check the machine taper, center-hole condition, support alignment and operating speed before installation. The center should be mounted on clean and properly matched contact surfaces.
What information is needed for quotation?
Please provide the machine taper, workpiece weight, support load, shaft length, center-hole size, speed range and machining process.
