Royal Quad Bearing Live Centers

• Accuracy: 0.00005″
• Three matched angular contact bearings with factory-set preload support the primary load area of the point.
• Special spindle-like point extends into the shank where it is supported by a needle bearing.
• This design substantially increases rigidity, reduces point deflection and dampens vibration.
• Bearings protected by a combination steel shield and neoprene seal.
• Point is high-carbon alloy steel heat treated to Rc 61 – 63.
• Included point angle is 60+15’/-0.
• Bearings permanently lubricated.
• Reduced knockout diameter prevents taper from mushrooming.
• Low profile head for tool clearance.
• Bearing life significantly extended with the exclusive Royal Roto-Shield.
• Made in the U.S.A.
