💡 How does C3 tolerance affect needle roller bearings in linear slide units and gearboxes? C3 clearance provides extra internal space to reduce contact stress and allow thermal expansion. - Better for applications with shaft growth, higher operating temperatures, or tight fits - Helps prevent preload from rising in linear slide unit installs and gearbox assemblies - Improves life under light misalignment and keeps needle roller bearings running cooler - Consider sealed ball bearing or ceramic options if contamination or extreme speeds are primary concerns
