Get PriceInternal clearance is how much the bearing’s rolling elements move within the raceway before the bearing is mounted to a shaft. A greater internal clearance means there is more space, or looseness, within the bearing. Internal clearance is most commonly expressed with the letter C followed by a number, with C0 being standard clearance.
