① When mating screw gears produced from the same material they may trigger abrasion and scoring. It is recommended to mate Screw Gears composed of different materials.

② The allowable torques confirmed in the table are the calculated values based on the assumed utilization conditions.

③ The backlash values demonstrated in the table will be the theoretical values for the backlash in the standard direction of a set ofidentical gears in mesh.

④ For offset shaft applications, match a RH with a RH, or LH with a LH, to make a group of screw gears. For parallel shaft applications, mesh reverse hands (RH and LH) of helical gear sets.

⑤ If the bore diameter can be less than φ 4, then your bore tolerance class is certainly H8. If the bore diameter is certainly φ 5 or φ 6, and the hole length (total duration) exceeds 3 times the diameter, then the class is also H8.
