that looks like a PF T47, it looks like a wide cylinder for a 386, and narrow? Either way, these press fit that screw together are very easy to install, you just need to buy the right tool, which is always cheap using AliX. There are lots of standards, but you can find the tool for each of them.
I recommend Liqui Molly 3312 on all the interfaces, that stuff is magical to avoid / remove BB creaks.
When you will want to remove it, you will need a BB removal tool. AliX also has it, the new versions have oval shaped things to REMOVE the BB. Typically with these "2 parts that screw together PF BBs", when you remove it, one part unscrews and pops off, and the other part is stuck in the frame. If you want to be civilised, you then use a BB removal tool.
Installing and removing PF BBs is good for the brain. you have 50 different bits in the kit and you got to find the right combo to achieve the desired goal.
