Precise High Performance Heavy Duty CNC Interchangeable Live Center Sets

• This live center has a combination of needle roll bearing, P5 class ball thrust bearing, and deep groove ball bearing.
• It’s application to medium to high speed machining with heavy duty load on CNC lathe.
• Adjustable needle roller bearing carry all radial loads while heavy duty ball thrust bearing carry all axial loads.
• With external shrink sleeve on the needle bearing, the clearance of the needle roller bearing can be adjusted to improve the precision adn service life of the live center.
• The 60 rotation spindle is made from bearing steel with heat treated to HRc 60+/-2 for high rigidity and wear resistance.
• Extra long spindle point extends into deep groove ball bearing supported shank to effectively improve rotating performance and reduce vibration.
• Lubricant can be added into the live center body to maintain lubrication on the bearing.
• Built-in oil seal protects bearing against ingress of coolant, dirt, and swarf.
