An ABEC 3 bearing is a roller bearing with a surface tolerance according to the ABEC standard. It has a precision class of 3 on a scale of 1 to 9, meaning it offers good precision, efficiency, and speed capacity. ABEC 3 bearings have grade 10 steel balls and a raceway made of 52100 chrome and high-quality carbon. These bearings meet the ABEC 3 standard and use either LLU or LLB seals. The LLB seal consists of a rubber seal with a metal core and has two lips for efficient sealing and smooth rotation. The outer lip keeps out water and contaminants, while the inner lip retains the grease for extended maintenance intervals.
