This gap is crucial for the function and longevity of the system.<\/p><p class=\"p3\">The clearance allows the parts to move smoothly without excessive friction, but too much clearance can lead to instability, while too little can cause wear and overheating.<\/p><p class=\"p4\"><b>1). Types of Clearance Fits:<\/b><\/p><ul class=\"ul1\"><li class=\"li3\"><p>Interference Fit: The shaft is slightly larger than the bushing, creating pressure between the parts.
