Shielded 6203-ZZC3 Ball Bearing in Standard brand with an inside diameter of 17mm, an outside diameter of 40mm, and a width of 12mm.

Shielded Bearings have metal seals that connect to the outer race only; this protects the bearing from dust and large solid particles but not from moisture. They are generally used in faster running machines as they have less friction than Rubber Sealed Bearings.

**Please note: This bearing has metal 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
