This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
錀 combines 金 (metal) with 侖, which likely contributes the sound. The exact historical development is uncertain, and the character is rare in modern Japanese.
The left side is metal 金, and the right side 侖 suggests a phonetic component. Without a clear meaning, picture a mysterious metal object with an unknown purpose.
For リン, imagine a rare metal ring made of 金: ring -> リン, and the ring is as mysterious as the kanji itself.
