Intra SFTA Single Flank Testing System with Twin Spindle and Axial Alignment
Gleason's Intra SFTA series leads the industry in single flank testing technology. It is designed for zero-point center distance to allow for all gear component to component testing. SFTA technology offers immediate feedback on transmission and gear microgeometry at the early design phase. As a compliment to single and twin spindle NVH testing systems, SFTA significantly reduces time for testing critical gear design data.

Most Versatile Solution in the Industry
The Intra SFTA is designed to measure a wide range of drivetrain components including: automotive EV gears, rotor and input shafts (assembled or bare), intermediate assemblies in any configuration, final drive output gears and differential assemblies.
SFTA Advanced Features
- Direct component to component NVH testing.
- Parallel-axis gear pair single-flank measurement.
- Realtime results during transmission early design phase & microgeometry development.
- Single-Flank TE and TA.
- CNC pitch & yaw adjustment to accommodate bearing assembly conditions.
- Direct component to component testing, rolling master not required.
Bearing Position Alignment
SFTA enables CNC machine adjustments for bearing positions and tolerances with embedded encoders measuring angle analysis (not time slice) for precision low order error evaluation. SFTA new cutting-edge technology is capable of detecting and identifying failure modes on single gears or gear pairs.
TA Torsional Acceleration Testing
Intra's TA system features a programmable CNC with constant center distance and supports test speeds of ±2000 rpm on either flank, in both directions. It delivers Intra "Pure Torque" of ±30 Nm, with multi-pass tests possible at varying torque levels and speeds. Certified for accuracy and systematic noise levels, Intra SFT series offering programmable order resolution from 0.125 to 1 with repeatability better than 1.2 dB. A configurable synchronous order range from 256 up to 4096 accommodates demanding applications such as special EV gears, with optional spindle condition monitoring via accelerometers.
Single Flank TE Analysis
Intra SFTA evaluates rotational accuracy of each flank versus a master/mating gear with high-precision Static and Dynamic Transmission Error. Intra's "Pure Torque" drive removes motor resonance, while automatic calibration eliminates fixture/master errors and aligns to journals. Advanced order analysis (ghosts, harmonics), SPC evaluation, flexible visualization, and a "Worst TE Order" indicator enable fast, reliable quality assessment.
CRITERION Analysis Software
CRITERION Analysis Software supports the complete inspection and analysis process of gears and other parts with rotationally symmetrical geometry. CRITERION puts powerful features right at your fingertips. The simple, intuitive human-machine interface improves operators' performance. Charts are easily configured to meet customer preferences or international standards such as AGMA, DIN, ISO, JIS, GOST, China GB, and others.
20+ Years – Hundreds of Systems
With over 20 years of development, hundreds of installations worldwide, and proven end-of-line correlation, Intra SFTA remains at the forefront of production gear inspection, offering advanced NVH capabilities with super-high-resolution, metrology-based transmission error analysis.
