What is the difference between 2Z and C3 bearings?
The 2Z suffix indicates that the bearing has a steel seal on both sides. The bearings are filled with a high-quality grease and are lubricated for life. The C3 in the product name means that this bearing has a higher (internal) clearance than normal. The C3 clearance is most frequently used for this type of bearings.
