Key features

The main body is forged from high-strength alloy tool steel (such as Cr12MoV or 40Cr), ensuring exceptional structural integrity and long-term fatigue resistance.

The working tip is heat-treated to a surface hardness of HRC 60-62, providing superior wear resistance and preventing deformation under heavy-duty loads.

Engineered with ultra-precision grinding technology, the radial runout is strictly maintained within 0.002mm - 0.005mm for flawless concentricity.

Equipped with a premium combination of imported deep-groove ball bearings, thrust ball bearings, and needle bearings for smooth, low-friction rotation.

The robust internal architecture is optimized to simultaneously withstand high axial thrust and radial cutting forces, providing rock-solid stability.

Features a triple-layer labyrinth seal and high-quality waterproof gaskets to effectively block coolant, metal chips, and dust from entering the bearing chamber.

Dynamically balanced for high-speed operations, supporting up to 5,000+ RPM with minimal heat buildup and zero vibration.

Available in standard, extended, slender, and carbide-tipped designs to provide optimal tool clearance for various workpiece geometries.

Fully compliant with Morse Taper standards (MT2 to MT6), the precision-ground shank ensures a perfect, rigid fit with the lathe tailstock.

By significantly dampening vibrations and enhancing rigidity, this live center helps achieve superior surface smoothness and tighter dimensional tolerances.
