Work up to a heavy single then do your working sets after, so your chest is used to the idea of one rep of heavy weight.
warm up your triceps before benching.
try messing around with your grip, I've got a narrow grip when I bench as my shoulder dexterity isn't great and it feels comfortable but a lot of people prefer a wider grip as the reps can be more controlled and less distance to travel.
That's what I'd suggest but I'm not a pro or anything haha.
