Acu-rite 558111-06 Dro Linear Scale 6 Inch

Product Description

The ACU-RITE 558111-06 is a glass DRO linear scale designed for digital readout systems used in precision machining applications. It delivers a measuring range of 6 inches with a resolution of 0.000050 inches and matching accuracy of 0.000050 inches, making it suited for milling machines, lathes, grinders, and similar CNC or manual machine tools. A 13-foot cable connects the scale to a compatible DRO display unit. Machinists, tool and die technicians, and machine shop operators rely on this type of linear feedback device to achieve repeatable, high-accuracy positioning during setup and cutting operations.

This linear scale fits standard DRO retrofit and OEM installations where a short-axis measurement range of 6 inches is appropriate. Typical applications include the Z-axis or cross-slide of a manual lathe, the quill or knee axis of a knee mill, or any machine tool axis where travel does not exceed 6 inches. The glass scale encoder provides the high-resolution linear feedback signal required by ACU-RITE and compatible digital readout displays in professional machine shop environments, both in job shop and production settings.

Key Features

• 6 inch maximum measuring range suitable for short-travel machine axes
• 0.000050 inch resolution for high-precision positioning feedback
• 0.000050 inch accuracy on glass scale encoder
• 13-foot cable length provides flexible routing to DRO display unit
• Glass scale construction for stable, low-thermal-expansion measurement
• Designed for digital readout equipment in industrial machinery applications

Compatibility

Designed as an OEM-style linear scale for use with digital readout systems in the Digital Readout Equipment category, including DRO installations on milling machines, lathes, grinders, and similar machine tools requiring short-axis linear feedback.

Installation Notes

Installation is typically performed by a machinist or qualified machine tool technician. Power down the machine and any connected DRO display before mounting or wiring the scale. The scale body and read head must be aligned parallel within manufacturer tolerances to ensure accurate signal output. Refer to the DRO display manufacturer's wiring documentation and applicable machine safety procedures before completing the installation.
