Abstract
A ready-to-install needle bearing including a thin-walled outer ring () that is shaped without cutting and is provided with radially inwardly-facing stop rims () on both sides. Needle rollers () roll between the stop rims () on an associated external raceway (). The inventive needle bearing is characterized in that an associated internal raceway () is formed by a thin-walled inner ring () which is shaped without cutting and is fitted with radially outwardly-facing stop rims () on both sides. The needle rollers () roll in a cageless manner or are disposed in a cage such that a captive ready-to-install needle bearing unit is created by using a positive gripping action, thus dispensing with the need for a part that is to be mounted having to act as a raceway.
