6216-ZZ Deep Groove Ball Bearing 79x140x26mm C3 Clearance Bearing Double Shield
The C3 clearance is larger than the standard clearance, which allows for more space between the rolling balls and the raceways. This increased clearance can accommodate thermal expansion, misalignment, and other factors that may cause slight dimensional changes in the bearing during operation.C3 clearance bearing is commonly used in applications where there may be higher operating temperatures or situations where slight misalignment or expansion is expected. It provides improved performance and reduced risk of premature failure by allowing the bearing to operate with less friction and heat generation.Steel Cages: Evenly space bearing balls to equal load distribution and prevent contact, effectively reducing friction, vibration, and noise.
