Super Precision Angular Contact Ball Bearing, Heavy Duty, Series: 2MM9300WI, 30 mm Bore Dia, 47 mm Outside Dia, 2 Rows, 9 mm Width, 15 °Contact, 9540 N Dynamic/6610 N Static, Phenolic Cage, 29700 RPM Max

2MM-WI types with 15 deg initial contact angle are designed to meet the needs of machine builders for precision bearings which will operate at as low a temperature as possible for a wide range of speeds and operating loads. In order for machines to produce more accurate work at a higher production rate, the bearings must provide a high degree of rigidity in both axial and radial directions while operating at minimum temperatures.
