Benefits of ROYAL HIGH-PRECISION QUAD-BEARING LIVE CENTERS

1. Low-profile head provides exceptional tool clearance.
2. +– 0.00005" TIR guaranteed.
3. Bearing life is significantly extended with the exclusive Royal Roto-Shield™ coolant slinger and a long-life, spring-loaded seal that is resistant to abrasion, high temperatures, and virtually all metalworking fluids.
4. Three precision angular-contact bearings are secured to the point with a locknut to form a rigid, preloaded assembly. This design is similar to a machine tool spindle cartridge and provides outstanding accuracy and rigidity.
5. The point extends into the body where it is supported by a needle roller bearing, which further increases rigidity, reduces point deflection, and dampens vibration.
   
6. Body and point are hardened and ground for strength and extended operating life.
