Super Precision Angular Contact Ball Bearing, Series: 9100, 35 mm Bore Dia, 62 mm Outside Dia, 2 Rows, 14 mm Width, 15 °Contact, Open Closure, Phenolic Cage, Uncoated

2MM-WO with 15 deg initial contact angle are designed for extremely high-speed applications where centrifugal force of the balls is the principal load on the bearing. Unlike the MM-WI type, which has a low shoulder outer ring, the 2MM-WO type has full shoulders on both sides of the outer ring and a low shoulder on one side of the inner ring. This design permits assembly with a maximum complement of balls and a one-piece cage that pilots against the precision-ground lands of the outer ring. This bearing series is generally supplied with a separable inner ring and ball retaining cage along with special race geometry allowing extremely high-speed operation.
