Kalkulator rozszerzalności cieplnej łożyska
Calculate separate uniform axial thermal changes of shaft and housing and their signed difference. Enter actual lengths, mean CTE values and temperature changes.

- L — effective initial span (mm)
- α — mean linear CTE over the stated interval (μm/(m·K), numerically ×10⁻⁶/K)
- ΔT — signed temperature change from the reference state (K or °C difference)
CTE input
CTE is material-grade and temperature dependent. Obtain a mean value over the actual interval from controlled material data rather than choosing a broad material-family label.

ℹ️ A locating/non-locating support can accommodate axial displacement from relative shaft/housing thermal growth, but required travel and bearing type must be selected from the complete arrangement loads, fits, tolerances and manufacturer data.
