We are trying to retain a bearing from coming off of a bearing mount plate. How do you keep it secure so that it won’t slide off? (We don’t have rivets)
We have done a couple of different ways over the years.
1.Shaft Colors or spacers to hold it in.
2. Drill and Tap Shaft, bolt with a washer that has an OD that matches the inside of the bearing.
3. Use 8-32 or 10-32 Screw heads to hold in the bearing.

Assuming the shaft goes across to another bearing on the opposing plate, you can cut & sand the shaft to the exact length so that it is flush with both bearings. Then if you tap the center of the shaft on both ends, you can install a screw and washer and this will retain the bearings and shaft
If you don’t have tapping capabilities, you can also cut the shaft a lil longer and place shaft collars on both ends

here is the easiest way to do it. Been doing it for over a decade. Would advise going to any local hardware store and getting rivets and a rivet tool. Will cost like 20-40 CAD for a rivet tool and 8 CAD for a 50 pack of rivets

Not optimal but if you don’t have taps or rivets, you can drill holes next to the bearing and put in bolts with washers to hold the flange on. (Unfortunately I dont have a photo but they were on our 2022 robot 
)
We definitely recommend using a 3d print over the bearing to hold it in place though!
We’re currently using that too.
Yeah we use a similar thing to the WCP bearing mounts, it’s 3-d printed with regular PLA, but holds the bearing down quite well. We have updated the design over the last 2 years. We use 2 #8-32 hex or button bolts spaced 2 inches apart to hold it down. Here’s the stl: bearingHolder.stl - Google Drive.
Take a look!
OP: Seriously. An inexpensive riveter and some rivets is an excellent investment. Rivets are far, far, faster to deal with than screws.
