What does C3 clearance mean?
C3 means the bearing has greater internal clearance than the Normal class before mounting. It describes the movement available between the bearing rings; it does not specify a different bore size.
Is C3 better than Normal clearance?
Use the clearance specified for the equipment. A tight mounting fit and temperature differences between the rings can change operating clearance. Check the machine specification before substituting a different clearance class in a motor, fan or gearbox.
Example: SKF 6315/C3
In SKF 6315/C3, 6315 is the basic bearing designation and C3 identifies the clearance class. If the box or bearing also carries markings for shields, seals or other features, copy them all. An enquiry that says only 6315 leaves out the clearance requirement.
