Product FAQ's

1. What types of spline gauges are available?

Dedicated Impex Co. offers GO and NO-GO spline plug gauges for internal splines and spline ring gauges for external splines. Types include involute splines, straight-sided splines, serrations, and special profile splines. Gauges are manufactured according to standard or customer-defined spline geometry and tolerance classes.

2. What industries commonly use spline gauges?

Spline gauges are widely used in automotive, aerospace, gearbox manufacturing, heavy engineering, machine tools, and power transmission industries. They ensure accurate spline engagement in drivetrain components, transmission systems, and torque-carrying assemblies requiring precision inspection.

3. How do spline gauges work?

Spline gauges operate on a functional GO/NO-GO principle. The GO gauge checks the maximum material condition to ensure proper spline fit, while the NO-GO gauge verifies that dimensions do not exceed minimum material limits. This fast pass-fail system ensures consistent production quality.

4. What standards do spline gauges follow?

Spline gauges are manufactured in accordance with ISO, DIN, ANSI/AGMA, and JIS standards. These standards define spline tooth form, module or diametral pitch, pressure angle, and tolerance classes, ensuring global compatibility and interchangeability.

5. What is the dimensional range of spline gauges?

Spline gauges are available in diameters ranging from Ø5 mm to Ø200 mm and support module sizes from 0.5 to 10. These dimensional ranges ensure suitability for checking spline form, pitch, and fit.

6. How accurate are spline gauges?

Spline gauges are manufactured with micron-level dimensional accuracy. Precision grinding and heat treatment processes ensure high repeatability, stable geometry, and long service life, even in demanding production inspection environments.

7. Can spline gauges be customized for special applications?

Yes, spline gauges can be customized in terms of spline profile, module, DP, number of teeth (up to 200), tolerance class, marking, and inspection standard. Special designs can be manufactured according to OEM drawings or application-specific requirements.

8. What is the role of spline gauges in load capacity assurance?

Spline gauges indirectly support load capacity by verifying accurate spline geometry. Proper tooth profile and fit ensure correct torque transmission, prevent stress concentration, and reduce the risk of mechanical failure under load conditions.

9. Can spline gauges be manufactured as per OEM drawings?

Spline gauges can be produced strictly according to OEM technical drawings. All dimensional tolerances, spline parameters, and inspection requirements are followed precisely to ensure compatibility with existing production systems and assemblies.

10. What export and quality compliance do spline gauges meet?
