QA hit A river and checked

Just had this hand in 0.01/0.02 cash game, I 3 xraised and have a pretty tight image was I right to check the river regarding the board

theres no chance for a flush, just a sequence with a 2 and set of 3... if anyone payed your raise with a low pocket, they would bet and nobody did it. So at the river u probably got the best hand.

Is ok to check the river

Yes, okay to check this river with the intention to bluff-catch. Unless there is a lot of action like a bet and a raise. Betting out half-pot to get value from Ax is okay too. Very unlikely anyone has a pocket pair 55+. I expect these type of players to bet to "see where they stand" with 55+ or to just take a stab when no one seems interested in the pot. Of course someone might be slowplaying a full house, but once the turn brings some straight draws, I'd expect them to bet out. We do have the best hand the majority of the time.
