| CAUTION: | For offset shaft applications, RH and RH or LH and LH are meshed to make up a set of screw gears or crossed-helical gears. For parallel shaft applications, mesh opposite hands for helical gear sets. See the "Selection Hints" in this catalog. |
|---|---|
| CAUTION: | Significant variations in temperature or humidity can cause changes in plastic gears (MC Nylon). Please see the section on plastic gears in the technical section. |
| NOTE: | The allowable torques shown in the table are calculated from the Niemann formula. Please see the "Selection Hints" for further detail. |
| NOTE: | The backlash values shown in the table are the theoretical values in the normal direction of a pair of identical gears in mesh. |
| USEFUL HINT: | Since the thrust forces vary according to the direction of rotation and screw, special care is needed to design the strength and placement of bearings. Please see the "Application Hints" and the section on gear forces in the technical section. |
