Royal 47100 Model A, 1.57 x 0.57 x 0.87 in

Our unique modular design covers a standard gripping range from 0.5 to 2.5 in, with specials available up to 25 in. Sleeves offer parallel expansion for maximum rigidity, and accuracy is guaranteed to +/- 0.0005 in TIR. Multiple mount styles and custom-machined drawtube connectors ensure simple, turnkey mounting on both main and sub spindle applications.

• Allows for full access to the entire length of the work piece so all external surfaces can be turned in a single operation, guaranteeing perfect concentricity
• On sub-spindle machines, ID gripping on the second spindle eliminates the risk of surface damage that can be caused by second-op OD gripping on a previously-turned diameter
• For many parts, the engagement-length of an ID bore can be greater than what is available for OD gripping, resulting in superior rigidity and torque transmission
• ID systems tend to be more streamlined than OD systems, enabling better part access - especially important for use on machines with live tooling
• Mandrel models A-E all have a common mounting interface with the body so the system can grow with your needs
• Expanding rod, expanding rod adapter, and mounting hardware included with each mandrel
• Mandrel models are defined by their gripping range
• 0.479-0.640 in gripping range

Includes: Expanding Rod, Expanding Rod Adapter and Mounting Hardware
