Calculator ((exclusive)) | Din 5482 Spline Dimensions

DIN 5480 utilizes a comprehensive flank-centering tolerance system (e.g., 9g, 7H). DIN 5482 uses a simplified tolerance approach primarily optimized for older sliding or fixed fits.

The calculator will provide detailed manufacturing and inspection data: For measuring tooth thickness or space width. Measure Over Pins/Between Pins ( Mdcap M sub d ): The critical inspection dimension. Span Width ( Wkcap W sub k ): The distance over k teeth. din 5482 spline dimensions calculator

For an external spline, the calculator will: Measure Over Pins/Between Pins ( Mdcap M sub

This is the most critical value for inspection. By placing precision pins in the tooth spaces and measuring the distance across them, you can verify if the spline was cut to the correct depth.
