Royal Live Centers

Royal live centers are widely regarded by top metalworking professionals as the best live centers available anywhere in the world. Each Royal live center is a finely crafted tool, incorporating the highest quality steels, bearings, and seals. Manufactured to exacting tolerances, all Royal live centers are guaranteed accurate to +/- 0.00005" TIR or better.

Royal Products offers a broad range of standard live center models to suit virtually all common turning applications. We also design and build hundreds of custom centers each year to meet special customer requirements. Custom live centers from Royal Products are competitively priced and are held to the same high manufacturing tolerances as our standard models.

A new development from Royal Products is the Exclusive Royal Roto-Shield, which significanlty improves a live center's effective operating life. Royal Roto-Shield Technology consists of two main components:

• A live center point that is machined from a solid bar and incorporates a specially-shaped coolant slinger
• An upgraded, 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:

• Coolant is deflected, keeping it from penetrating the center
• Bearings are protected from harmful fines and dust
• Seal wear is minimized
• Lubricating grease lasts longer and retains consistency

The Royal Roto-Shield is now a standard feature on the following Royal Live Center models:

• High Precision Quad Bearing Live Centers
• High Precision CNC Quad Bearing Live Centers
• Heavy-Duty Spindle Type Live Centers
• Heavy-Duty CNC Spindle Type Live Centers
• High-Speed Precision Live Centers
• Super Quad Extra Heavy-Duty Live Centers
