There’s a reason why you won’t find one.
The needle would be 3mm diameter & that cuts down the count or number of needles, simply need more needles at a smaller diameter for loading.
Just press a Koyo JR12x15x16 “inner ring” sleeve into the wrist pin rod end hole. Trim the sides off to your 15mm width. See Page 105 in the link below. Then use a common 9x12x15mm wide caged needle bearing like the K9x12x13FV on page 65, but wider if needed.
