An interference fit keeps the shaft larger than the hole and relies on elastic deformation, insertion force, heating, cooling, or a combination.<\/p>\n<h3 style=\"font-size: 20px; line-height: 1.25; margin-top: 36px; margin-bottom: 14px;\">Clearance is a performance window<\/h3>\n<p style=\"font-size: 15px; line-height: 1.82; margin-bottom: 16.5px; text-align: left;\">Too little clearance can cause seizure after temperature rise, coating, contamination, or misalignment.
