Open 6311-C3 Ball Bearing in Standard brand with an inside diameter of 55mm, an outside diameter of 120mm, and a width of 29mm.

Generally used in gearboxes or areas that are not subject to dust or moisture, open bearings have no seals or shields, allowing oil or grease to flow through the bearing for lubrication purposes.

**Please note: This bearing has no seals or shields.

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
