I had these rocker bearing phospher bronze roller cages made to the original 'Imperial' size, for those customers that wanted to replace the rocker pins with my new items, but did not want to go to all the troube of fitting complete new outer bearing sets (which I show listed seperatey). Unfortunately the original 'imperial' size rollers are now obsolete and unobtainable - so make sure you save your originals and you think they are good enough to re-use!!
However, that being the case- you can at least replace the old worn bronze cage with this replacement, which together with a new rocker pin should be a reasonable and cheaper alternative to replacing everything.
This listing is for a single phospher bronze replacement imperial cage
