Product catalog summary

Specifications
The document specifies ground spur gears with precision grades JIS N5 and JIS 1. These gears have standard full depth teeth and a 20° pressure angle. The material used is SCM415, treated with overall carburizing heat treatment to achieve a tooth hardness of 55 to 60 HRC.

Product Characteristics
Keyway dimensions follow JIS (Js9) tolerance, though heat treatment may cause deviations. Allowable torques are based on assumed usage conditions, and backlash values are theoretical for identical gears in mesh. Products marked with "**" have limited material between the keyway corner and tooth root, which should be considered during selection.

Product Range
The catalog includes modules 1, 1.5, 2, and 2.5, with detailed specifications for each gear, such as the number of teeth, shape, bore, hub diameter, pitch diameter, outside diameter, face width, hub width, total length, web thickness, and web outer diameter.

Allowable Torque and Backlash
Tables provide detailed data on keyway dimensions, allowable torque (bending strength and surface durability), backlash, and weight for each gear model.

Caution on Secondary Operations
Secondary operations are not possible on these precision-finished gears due to the carburizing process. Custom gear orders are available for different specifications.

Additional Products
Other gear types mentioned include helical gears, internal gears, racks, pinions, miter gears, bevel gears, screw gears, worm gear pairs, and bevel gearboxes. For updated information, refer to the KHK Web Catalog.
