Bore Gage Calibration Services
Inside diameters hide their errors — the bore gage’s job is not to add its own.
ACS Calibration delivers NIST-traceable, audit-ready bore gage services, available at the ACS central lab or directly on-site at facilities across the Southeast. Calipers, micrometers, height gages, and indicators are all on our accredited dimensional scope, so ISO/IEC 17025 accredited certificates are available on request.
Honest Numbers From Inside the Hole
Dial bore gages, cylinder gages, and their indicator heads measure the features that matter most and forgive least: bearing bores, cylinder walls, bushing fits. Contact wear, linkage play, and indicator drift stack into readings that decide press fits and clearances.
We calibrate bore gages under our accredited dimensional scope — setting references verified against gage blocks, indicator travel checked through the range — with as-found and as-left data. The telescoping gages and indicators in the same drawer calibrate alongside.
What You Get With Every Calibration
- NIST-traceable calibration certificate with real measurement data — not just a pass/fail sticker
- As-found and as-left readings, so drift is documented
- ISO/IEC 17025 accredited certificate with reported uncertainty — on request
- Calibration label with due date, plus a reminder before your next calibration is due
Why Companies Choose ACS for Bore Gage Services
NIST-Traceable, Accredited on Request
Every calibration is NIST-traceable with real measurement data. Calipers, micrometers, height gages, indicators, pin gages, and feeler gages are on our ISO/IEC 17025 accredited dimensional scope — accredited certificates available whenever your quality system requires them.
