My brand new Volvo sterngland runs at about 50c measured with an ir thermometer on the outside surface. Greased and burped as required. Is this normal? I didn't expect it to get hot at all. Previous gland was stuffing box.

sounds hot to me - do you mean the shaft or the rubber sterngland? Assuming you have sized it correctly then I wonder about alignment of the rubber 'cutless' bearing inside the sterngland with the shaft..

I have one which i have never checked with IR but i have felt it after a long spell of motoring.
It was warm. Difficult to say if it was 50c.
Just a shot in the dark , are you sure it's the correct size , ie. not a s5mm gland with a 1" (25.4) shaft ?
No excessive vibration or shaft missalingment ?
Otherwsie if it's working Ok and not leaking just keep an eye on it............

Are you sure it was burped properly , did you get all the air out and only spurts of water left ?
The seal has 2 lip seals and a comparatively long 'guide section'.
Can't see the seal lips generating too much heat but the guide section , maybe.

I don't have a Volvo seal but I would say 50c is hot to the touch. With all that cold water up to the lip seals on the inside I would think something is wrong if it's 50c on the outside.

Hi,
I have a 30mm volvo seal on my sailboat and frequently check its temperature with an IR meter.
The temperature of the seal is typically 33-35C in summer when motor cruising at about 1200 shaft rpm (2500 engine rpm) for many hours with a near perfect shaft alignment.
Sometimes back I cruised with a gross misalignment in the shaft (about 0.6mm) and the seal temperature was hotter at about 42-45C. I also accidentally ran for about 15 minutes with air trapped in the seal and in that case the temperature went up to about 55C.

Not normal. Mine runs just a touch warm and that after a few hours running! I changed it 18 months ago before coming to Portugal. Crossing Biscay, the first day and night we sailed then the wind changed to on the nose, I put the donk on. It was on for two days and nights. After the first 24 hrs there was a noise, I checked the seal,it was hot, like yours. i greased it and burped it, there was a lot of air in it! It then worked fine all the rest of the way to La Coruna. Going down the Spanish and Portugueses coast I did this a couple of times. Even though Bene have a water bleed pipe in it it seems to have an issue with needing burping if running for a long time. i checked the alignment of the engine whilst in the water. It is ok
