For General Industry

Cautions/prohibitions

Cautions/prohibitions

  1. 1. The material of plastic gears expands and contracts depending on the temperature and humidity, and the dimensions such as hole diameter (H8 when manufactured), tip diameter, backlash change. Please check "design of plastic gears" in the gear technical data for your study.
  2. 2. Using the same material for screw gears may cause wear and galling, so the combination with other materials is recommendable.
  3. 3. The allowable torque shown above is a reference value calculated under arbitrary usage conditions. Please check the precautions for details.
  4. 4. The backlash shown above is the normal backlash when assembled with the same part number at theoretical value.
  5. 5. When using for skewed shafts (screw gears), it becomes a combination of helices in the identical direction (right and right or left and left), and when using for parallel shafts (helical gears), it becomes a combination of different helices (right and left).

Precautions for alteration

  1. 1. For alteration to screw gears, it is necessary to check "precautions for alteration" in the precautions for safety before alteration.
  2. 2. Please refrain from processing to narrow the tooth width because it will affect the accuracy and strength of the gear.
  3. 3. Plastic gears are products that are easily affected by temperature and humidity. Please note that there may be changes in dimensions during and after processing.
