MT4 (Morse Taper 4) Medium Duty Live Center (MPN: 3900-5004)
This listing is for a new, high-performance MT4 Medium Duty Live Center. This is the perfect upgrade for any medium-to-large lathe with a Morse Taper 4 tailstock, providing the rigidity and accuracy needed for serious turning work.
This center is engineered to handle higher speeds and heavier loads than “light duty” centers, thanks to its robust internal bearing system.
Technical Specifications & Improvements
Taper: MT4 (Morse Taper #4)
MPN: 3900-5004
Point Angle: 60° (Standard)
Point Material: High-Alloy Steel, Hardened to HRC 60-62 for exceptional wear resistance.
Accuracy: Guaranteed concentricity of 0.0002″ T.I.R. (Total Indicated Runout) for precision work.
Body: The main body and MT4 shank are hardened and precision ground for a perfect fit and reduced vibration.
Enhanced “Medium Duty” Bearing System: This live center features a robust triple bearing system specifically designed to handle both:
Axial Loads (Thrust): A precision tapered roller bearing absorbs the heavy pressure from the tailstock.
Radial Loads (Side): Two high-quality ball bearings ensure the point spins smoothly and resists deflection during cutting. A high-quality seal at the front protects these bearings from coolant and chips, ensuring a long, smooth service life.
Applications
This is the ideal live center for:
General turning and facing
Supporting long or heavy workpieces
High-speed turning operations
Any lathe with an MT4 tailstock
