Specifications:
The document provides specifications for Angular Miter Gears, specifically the KSAM series. These gears are precision grade JIS B 1704: 1978 grade 3, with Gleason gear teeth and a pressure angle of 20°. The material used is S45C, and the tooth hardness is less than 194HB. No heat treatment is specified.

Product Details:
The KSAM series includes gears with shaft angles of 45°, 60°, 90°, and 120°. The document lists various modules (1.5, 2, 2.5, 3) and provides detailed measurements for each, including hub width, bore length, face width, and holding surface diameter. Allowable torque values are given in both N·m and kgf·m, along with bending strength and surface durability.

Dimensional Information:
The document includes tables with dimensions such as bore, hub diameter, pitch diameter, outside diameter, mounting distance, total length, and crown to back length for different gear configurations.

Cautions:
The document advises that allowable torques are calculated based on assumed usage conditions and that dimensions are theoretical, with potential variations due to gear tip chamfering. It also notes that shaft angles are determined when two identical products are paired, and pairing different products will not change the shaft angle.

Secondary Operations:
There is a caution regarding secondary operations, advising users to refer to specific guidelines for safety concerns.

Custom Gear Production:
For products not in the stock series, custom gear production services are available with short lead times.
