The rise in global car sales is expected to drive the growth of the spline measuring instrument market going forward. Global car sales refer to the total number of passenger vehicles sold worldwide across major automotive markets. Car sales are increasing due to growing consumer demand for personal mobility and improved vehicle features. Spline measuring instruments are used in automotive manufacturing to precisely inspect spline shafts and gears, ensuring accurate fit and smooth power transmission. For example, in March 2025, the European Automobile Manufacturers’ Association reported that global car sales reached 74.6 million units in 2024, a 2.5% increase compared to 2023. Therefore, the rise in global car sales is driving the growth of the spline measuring instrument market.

Major companies in the spline measuring instrument market are focusing on developing advanced technologies such as nano-level gear inspection systems to improve precision and efficiency in gear manufacturing. Nano-level inspection systems use high-precision scanning probes and advanced software algorithms to measure gear dimensions, surface roughness, and noise characteristics with sub-micrometer accuracy, enabling manufacturers to optimize product quality and performance. For instance, in May 2024, Gleason, a US-based machine industry company, introduced the 175GMS nano Gear Metrology System with an expanded measurement range. The system features skidless probes for submicron surface inspection, a high-precision SP25 3D scanning probe head, and advanced roughness evaluation software compliant with DIN, ISO, and ANSI standards. It also incorporates GAMA 3.2 software for gear noise and 3D GD&T analysis, closed-loop connectivity for automated machine adjustments, Smart Loop integration with KISSsoft Design Software, and an optional Advanced Operator Pendant for remote monitoring and streamlined inspection workflows.

In January 2024, Euro-Tech Corporation, a US-based distributor, partnered with Frenco to deliver advanced gear and spline metrology solutions designed to address complex workholding and gauging challenges across aerospace, automotive, and gear manufacturing industries. Frenco is a Germany-based gear and spline metrology company specializing in the production of spline gauges.
