Live Centers for Intermittent Use
These light duty centers are for intermittent use on manual lathes. Use live centers in the tailstock to support the end of a workpiece. With bearings to support their free-turning point, they produce minimal friction between the center and workpiece. For increased tool life, the bearings are lubricated and sealed to protect against fluid and chips.

Live Centers for Continuous Use
A hardened body and point provide the extra strength and wear resistance necessary for continuous use on manual or CNC lathes. Use live centers in the tailstock to support the end of a workpiece. With bearings to support their free-turning point, they produce minimal friction between the center and workpiece. For increased tool life, the bearings are lubricated and sealed to protect against fluid and chips.

Pipe and Tubing Live Centers
Also known as bull-nose centers, these have a wide head to hold pipe and large-diameter tubing. Use live centers in the tailstock to support the end of a workpiece. With bearings to support their free-turning point, they produce minimal friction between the center and workpiece.

Precision Alignment Bars for Lathes
Turn straight and true—use these bars to confirm that your lathe headstock and tailstock are right inline. Insert the bar between the centers of your headstock and tailstock, then use a variance indicator (not included) on the bar ends. Any difference will register since the bar ends are precision ground to within 0.0002” of each other.
