Recommended for shaft diameters in this range for normal stress. Why the "Exclusive" Tag Matters
: A relief groove used when only the cylindrical surface (the shaft) requires further machining, and no high fatigue load is expected on the planar shoulder. 0.6 (Radius ) : The radius of the undercut profile is 0.6 mm . 0.2 (Depth ) : The radial depth of the groove is 0.2 mm . Technical Dimensions din 509e06x02 exclusive
For this specific size, the standard typically specifies the following additional dimensions to ensure proper tool clearance: Value (mm) Depth Breadth (Width) Run-out Angle 15° (Standard for Type E) Application Guidelines Workpiece Diameter ( Recommended for shaft diameters in this range for
: Specifies a form intended for workpieces where the planar surface (shoulder) is not subjected to high fatigue loads and does not require special treatment. It is primarily used when the cylindrical surface may need further machining but the shoulder does not. : This value represents the of the undercut in millimeters. : This value represents the of the recess in millimeters. Key Specifications Description The curvature at the bottom of the groove. The penetration depth into the workpiece. Surface Roughness (Standard) Standard roughness is typically unless otherwise specified. Application Rotational Parts : This value represents the of the undercut in millimeters
