WESTport helical spline ring gages inspect external helical splines — teeth that follow a helix around the shaft rather than running straight along it. Each gage is manufactured for the specific helix angle and spline specification of the part being inspected.
Standards & setup
Manufactured to ANSI B92.1, ANSI B92.2M, ISO 4156, DIN 5480 and related standards, or to your print. Because the gage is cut to the part's helix angle, that angle and hand must be specified on the request. Compatible with taper master plug gages for setup and verification.
Certification & quality
- Designed, ground, and hand lapped in-house for accuracy and long service life
- Certificate of Accuracy, NIST-traceable — included with every gage
- Calibrated in our ISO/IEC 17025 accredited laboratory; Long Form Certificate available on a 5–7 business day turnaround
