A bearing includes a split outer race having a first outer race member and a second outer race member that form an annular ring. The bearing includes an activation member that is rotatable from a first position to a second position and is at least partially disposed in the annular ring. A locking feature is defined by the first outer race member, the second outer race member and the activation member. The locking feature has an unlocked position and a locked position. The unlocked position corresponds to the first position of the activation member and the locked position corresponds to the second position of the activation member.

An outer ring for a roller bearing includes a raceway produced from a bearing steel. The outer ring is made of a metal strip wound to form a raceway tube and a cladding tube which is connected thereto and which surrounds the raceway tube on the outer side.

An alignment device aligns rollers R in an annular shaped alignment space 24 in parallel to each other while at the same time prevents damage from occurring on rolling surfaces of rollers R. Plural rollers R that are arranged in a row in an axial direction are sequentially supplied into an annular shaped alignment space 24 that is formed in a main jig 14 in a direction that coincides with a width direction of the alignment space 24. The plural rollers R are aligned in an annular shape so as to be in parallel to each other by alignment-fluid-supply means 16 spraying air onto a roller R that is in a supply position in the alignment space 24 from a direction that is orthogonal to the roller R supply direction and moving the roller R in a circumferential direction of the alignment space 24, and then supplying a next roller R into the alignment space 24.
