Din 5482 Spline Dimensions Calculator Repack

The DIN 5482 standard, though officially withdrawn in 1987 in favor of DIN 5480, remains a cornerstone for repair and maintenance of legacy machinery. It defines involute splines with a 30° pressure angle and is primarily used for flank-centered connections. Key Dimensions and Parameters

• Torsional moment capacity (approx)
• Shear stress at root diameter

Q3: What is the maximum torque for a DIN 5482 spline? There is no single value. It depends on length of engagement, material, and lubrication. The calculator can estimate based on root diameter shear area. din 5482 spline dimensions calculator

2. Tolerance Verification

DIN 5482 involves specific tolerance fields (often denoted by letters and numbers like 9H or 8f). A good calculator will show you the Maximum Material Condition (MMC) and Least Material Condition (LMC), ensuring your design is manufacturable. The DIN 5482 standard, though officially withdrawn in

9. Important Notes / Disclaimers

• ⚠️ DIN 5482 was withdrawn and replaced by DIN 5480 (modular, 30°–37.5° PA) and DIN 5481 (serrations). However, DIN 5482 is still widely used in legacy designs.
• ✅ This calculator follows the 1991 version (last active standard).
• 🔧 For manufacturing, always verify with original standard drawings.

Circular pitch:

• ✦ H7/h7 (Sliding fit)
• ✦ H8/f8 (Loose running)
• ✦ H7/js6 (Light press)
