Live Centers • TURNING 335 PRECISION HEAVY DUTY LIVE CENTERS Allow For Higher Turning Speeds With Less Heat Achieve Precision Results Without The Need For Separate Lubrication Thanks to the precision triple bearings, the 60° center point moves freely with the workpiece being turned to help reduce friction and heat at high speeds. A special steel ring protects the precision bearings to help you achieve your desired results. FEATURES: • The rotating spindle is extended right through the tapered shank. • Two specially designed adjustable needle-roller bearings carry all radial loads. • A heavy duty ball thrust bearing takes all axial thrust. • Thermal expansion and shock loads are absorbed by a special compensator spring. • Complete protection of bearings from the ingress of coolant, dirt or swarf is provided by the built-in oil seal, which also prevents loss of lubricant. Cfrreicattieonlewsshenthetrumrnaling Problem: Friction and heat buildup during high-speed turning can be dangerous enough to damage materials and tools. Solution: Pair of adjustable bearings allows versatile center point movement that alleviates pressure and buildup during machining.

Royal Roto-Shield ™ Technology consists of two main components: • A live center point machined from a solid bar which incorporates a specially- shaped steel coolant slinger. • A long-life, spring-loaded seal that is resistant to abrasion,high temperatures, and virtually all metalworking fluids. A dramatic increase in operating life is achieved through the following effects: • C oolant is deflected, keeping it from penetrating the center. • B earings are protected from harmful fines and dust. • S eal wear is minimized. • L ubricating grease lasts longer and retains consistency.
