Occasionally a big end does turn up with 'crowded rollers' and no cage...They may have been after market items back in the day or perhaps a BSA big end with the cage discarded and more rollers fitted as the cages can get damaged/worn...I've never checked to see if that arrangement is dimensionally possible.. However, they are uncommon...In 50 years and over scores of different engines I've come across only four or five of the type...Ian
