Status: unmeasured
Provisional grouping for the Riwa RA-series rotary cluster. A JD indexed snippet claims the "RIWA original" head fits RA-5301, RA-5503, RA-5505, RA-5308, RA-5309, and RA-5310. A separate JD price / search result advertises a non-original "four-petal rotary interface" ("四瓣旋转式接口") head fitting RA-5505 and related devices. Exact original head SKU was not captured. Spelling varies ("RA-5505", "RA5505", "RA--5505"). The "357A" token appears in marketplace titles but is not proven as an official head or device SKU.
Notes¶
Riwa RA-5505. ZOL / Yesky classify the RA-5505 as a rotary three-head body. JD indexed snippets list both an "original" RIWA head and a non-original "four-petal rotary interface" ("四瓣旋转式接口") replacement. The "four-petal" phrasing may encode an interface clue similar to the Xiaomi five-sided shaft vocabulary, but it remains a marketplace claim with no measured geometry.
