[Precautions Related to Product Characteristics]

  • Allowable torque shown is a reference value calculated under arbitrary use conditions.
  • The stated backlash is the backlash in the normal direction and assumes that parts from the same dies are assembled under the theoretical values.

Cautions/prohibitions

Precautions for alteration

  • Please pay attention to safety when altering products.
  • Avoid narrowing down the tooth width because it affects the accuracy and strength of the gear.
