.GEAR TECHNICAL DATA |
We have gathered our extensive knowledge about gears and compiled it into a “Technical Data Document”, in order for our customers to refer to when designing, selecting and using our gears to their maximum potential.
It contains an extensive amount of information regarding gear terminology, how to use and measure gears, explanation of accuracy grades for gears, as well as dimensions and strength calculation formulas for many types of gears.
We also hope this Technical Data Document helps provide helpful insight for all those who would like to design, use or study gears.
