Product catalog summary

Specifications:
The document details the specifications for ground spur gears with modules 0.5, 0.8, and 1.5. These gears adhere to precision grades JIS grade N7 (JIS B1702-1: 1998) and JIS grade 3 (JIS B1702: 1976). They feature a standard full depth with a 20° pressure angle. The material used is S45C, with tooth hardness ranging from 200 to 270HB for modules 0.5 and 0.8, and 50 to 60HRC for module 1.5, which is induction hardened.

Product Characteristics:
The document includes tables with gear models, dimensions, and mechanical properties such as allowable torque, bending strength, surface durability, backlash, and weight. Set screws are included for products with tapped holes, and S1T shaped set screws are recommended for light load usage.

Procedures and Recommendations:
It is advised to use dowel pins with set screws for secure fastening. The document emphasizes reading the 'Caution on Performing Secondary Operations' section for safety when modifying gears. The KHK Quick-Mod Gears system is available for quick modifications.

J Series Products:
J Series products require a lead-time for shipping and are available in quantities of 1 to 20 units per order. Keyways are made according to JIS B1301 standards with Js9 tolerance. Some products may have counterbored tapped holes to reduce tap length.

Additional Notes:
The document cautions that re-worked areas will not be black oxide coated. It also notes that allowable torques and backlash values are theoretical and based on assumed conditions. Poor tooth contact was observed on SSG3-30, leading to pitting after 60 hours of operation under specific conditions.

Performance and Cautions:
Allowable torques and backlash values are provided for different gear configurations. Secondary operations should be performed with caution, especially on induction-hardened tooth areas.

Additional Information:
Custom gear production services are available for products not in the KHK Stock Gear series. Gear oil equivalent to JIS gear oil category 2 and No. 3 is recommended for use.
