Sony BB25 Backer Bar Dro Accessory

Product Description

The SONY BB25 is a backer bar accessory designed for use with digital readout (DRO) systems. Backer bars provide a rigid mounting surface or support structure that helps secure DRO scale assemblies and related components in precise alignment. This part is typically installed by machinists, tool and die technicians, or precision measurement professionals working on mills, lathes, grinders, or other machine tool setups that require accurate positional feedback. The BB25 weighs 0.9 pounds, making it a compact, lightweight hardware component suited to bench or machine installation.

The BB25 backer bar is used wherever a DRO scale or reader head needs a stable backing surface to maintain consistent measurement accuracy. Typical applications include retrofit DRO installations on manual milling machines, surface grinders, and lathes in machine shops, toolrooms, and light manufacturing environments. Installation is straightforward and generally requires basic hand tools.

Installation Notes

Installation should be performed by a qualified machinist or precision measurement technician familiar with DRO system assembly. Power down any associated electronic readout display or machine control before working on mounting hardware. Use appropriate hand tools and follow the DRO manufacturer installation guide to ensure proper alignment of the scale assembly. Avoid overtightening fasteners, which can distort the backer bar and affect measurement accuracy.
