I can remember a few years back when our brakes weren't working on the front axle. Bearing temp was about 35 degrees C. Of course the summer temp is going to be higher than the winter temp. I'm generally not worried about bearing temp if I know there is plenty of grease there. Temp of brakes is significant though, the temp gun lets us make sure the braking effect is sort of uniform.
But before you panic about your readings, understand that temps rise and fall as a result of ambient temps and the road. Make sure there is a problem before you create one.

My temperature gun is a finger on the drum after a long run,if it's running hot which happened on my brother in laws van on one trip, the problem was solved by backing off the bearing nut a fraction to give more clearance.
We are getting techi with heat guns ?? Lol yes just use my hand also . Clearance and grease, lube quality is the main things .. Once a year or before long trip I repack bearings .. Never has a problem .. Even on boat trailers ..
When we stop I just go around all 4 wheels and touch the bearing cap. If it's too hot then something is in need of fixing NOW.

Same here - no high tech stuff just hand on the cap and side of the tyres when stopped after a run. Have done the same for many years with both vans and boats. But beware, don't grab hold - just touch to feel, because if there is a problem then you can get burned!!!!!!
Fingers for 50 yrs. Gun for around 3.
