Reply to comment by whayd in What’s the best way to create smooth movement between a wheel and a 2x4 axle? by whayd

Then it shouldn't matter if the axle moves smoothly or is locked in place as the smooth motion of the wheels comes from their bearings. In that situation, you could even fix the axle rigidly to the 4x2 and it will work fine.
For something like that, I'd be tempted to use threaded rod and have washers and nuts clamp the axle in place then use nuts to clamp the inner race of the bearing to the axle

That’s my current setup actually. The steel rod is held rigidly by the conduit clamps. The wheel turns around the rod, and only occasionally “engages” the bearing (it basically moves around the axle without needing the bearing). Is it common/recommended to secure the inner ring of the bearing to the axle so the bearing remains stationary?

In other words… the wheel has a 5/8 bore. Rod is 5/8 diameter, but there’s still a bit of play, so the bearing isn’t snug.
