• 10 units per order of the World Champion ACER Racing Stainless 4x10x4mm Ball Bearings are available. These ball bearings, sometimes referred to as size MR104 ball bearings, are 4x10mm in size. HSR inner cage technology, protected on both sides, and stainless steel balls. Fast and incredibly smooth action is ensured by the use of American ACER Racing SIN oil, which is 100% synthetic and lightweight. A true ABEC 5 grade for great precision.
• These are very popular for use in 4x10mm fishing reel bearings, which enable you to cast further and longer, but they can be used anywhere a 4x10x4mm bearing is needed. They are made entirely of stainless steel, so there is no need to disassemble them or clean them because the best synthetic oil has already been applied.
