These interchangeable, precision hubs secure your disk media on Semprex Disk Stages. A special machining technique is used to ensure excellent concentric rotation of the media. The hubs are made of a plastic material and support the media on a small lip on the inner diameter of the disk, greatly minimizing the risk of any damage to the media during inspection.

Features:

• Interchangeable hubs fits all Semprex Disk Stages
• Very accurate concentric rotation (+/-0.0005 inch)
• Made of Acetal plastic to prevent damage to media
