Sealed 6311-2RS1C3 Ball Bearing manufactured by SKF with an inside diameter of 55mm, an outside diameter of 120mm, and a width of 29mm.

Generally used for wheel bearings or any application where dust or moisture is present, sealed bearings have rubber seals that contact both the inner and outer race of the bearing preventing moisture and dust from damaging the bearing.

**Please note: This bearing has rubber seals.

C3 bearings have a larger clearance around the balls allowing the bearing to cope better with heat expansion, this means the bearing runs freer and smoother at higher temperatures. C3 Bearings also cope better in start/stop applications, they are found in almost every electric motor produced and are commonly found in washing machines and tumble driers
