Decoding the designation

6216 is the ISO 62 medium series at an 80 mm bore. C3 is radial internal clearance greater than normal. Written as 6216/C3, 6216C3 and 6216 C3.

What these specs mean in practice

Dynamic Load Rating: 72,800 N. Static Load Rating: 55,000 N. Reference Speed: 9,500 rpm. Limiting Speed: 6,000 rpm. The bearing carries radial load and axial load in both directions, and the deep raceway grooves are what give it that two-way thrust capacity. C3 clearance leaves more room between balls and raceways at rest, which is what an interference fit on the shaft, a tight housing fit or a hot inner ring consumes once the bearing is running — so C3 is the choice where the shaft runs warmer than the housing. SKF Explorer is SKF’s upgraded steel and finish specification, and it is what lifts the dynamic rating above the older 6216 figure on the same envelope.

Quantity and configuration

Unit Quantity: 1 Pc. One bearing per sale unit, open on both faces, greased on assembly by the user.

Mounting data

Shaft abutment diameter: 91 mm minimum. Housing abutment diameter: 129 mm maximum. Shaft and housing fillet radius: 2 mm maximum. Bearing chamfer r1,2: 2 mm minimum. Those four figures set the shoulder the bearing rings seat against, so the rings are supported over their full side face and the fillet clears the chamfer.
