A precision rotating center component in lathe tailstocks for supporting long workpieces during machining operations.
The Center is a critical rotating component mounted in the tailstock of a lathe or similar machine tool, designed to provide axial support to long workpieces during turning, facing, or drilling operations. It consists of a precisely machined conical point that engages with a center hole in the workpiece, mounted on bearings to allow rotation with minimal friction. This component ensures workpiece stability, reduces deflection, and maintains alignment between the headstock and tailstock, enabling high-precision machining of cylindrical parts.

A live center (rotating center) contains bearings that allow it to rotate with the workpiece, reducing friction and heat. A dead center is stationary and requires lubrication between the center and workpiece, typically used for lower-speed applications.
Select based on your lathe's tailstock taper specification (commonly MT2-MT6). Match the Morse taper number to your machine's tailstock spindle. Larger tapers provide greater rigidity for heavy-duty applications.
Regular cleaning to remove chips and debris, periodic lubrication according to manufacturer specifications (typically every 200-500 hours), and checking for bearing play or runout. Replace when runout exceeds 0.01 mm or bearings show signs of wear.
