Stringent quality control
Our procedures specific to each stage of the manufacturing process allow us to control quality from the very first part onwards. Our testing and traceability procedures respond to the needs of all industrial sectors, so we can master the specifics of your parts without unnecessary costs. In addition to traditional methods, we test the geometry of your parts using digital measuring machines. We test and inspect our gear teeth across the entire ISO parameter spectrum.Gear design and engineering
Using the most dependable software, SPR will design your gear train to your specification. Our design office will help you determine or approve the characteristics and specifics of your application. Because the performance of your gears depends on so many parameters, teeth can often be optimised to guarantee the best efficiency, torque and longer life.
