Shrink Fit Temperature Calculator

Determine the target heating temperature to expand a bore for a slip-fit assembly.

Inputs / Parameters

Formulas used:
Total Expansion Required = Interference + Clearance
Temperature Delta (ΔT) = Total Expansion / (Diameter × CTE)
Target Heater Temp = Ambient + ΔT
Clearance ensures the shaft can drop in easily without hanging up during the rapid cooling phase. Typical slip clearances range from 0.001" to 0.003".
