Looking at all the bite force studies and charts that we have, it has pretty much been established that Agriotherium Africanum had the absolute highest bite force of any bear in history, while the sun bear and panda bear have the strongest bite force relative to its size. Sun bears its believed because it can bite hardwood trees in pursuit of insects, and Panda bears because they eat bamboo.

The most extensive study on bite forces has been conducted by Christiansen and Wroe in 2007; just like King Kodiak said, however, there are two things that would need further investigations in my eyes:
1. The jaguar has always been considered to have the strongest relative bite force among all cats; yet he sits behind the cougar/leopard in this study; maybe due to a small sample size? 2. The spotted hyena has been labeled a powerful bone crusher and yet has a relatively low BFQ (99.9) in comparison to the brown hyena/striped hyena; maybe also due to a small sample size?

The sun bear has a surprisingly powerful bite. I say surprising because he feeds on ( to my knowledge ) mostly soft fruits and honey. Both of the bears not of the subfamily Ursinae have extremely powerful bites; the giant panda and the Andean bear. I was really surprised with the spotted hyena; but perhaps 'Taker has discovered the problem. The scavenger who leaves behind hardly any leftovers should have a wicked bite-force.

/\ Spotted hyenas do have an extremely strong crushing bite but their canine pressure might not be as strong and slicing bite not as efficient.

Feeding ecology and morphology of the upper canines in bears (carnivora: Ursidae)
The morphology and mechanical strength of the upper canines in all eight extant species of ursids is analyzed, and the findings are discussed in relation to feeding ecology. Ursids have proportionally smaller canines than other large carnivores with a specialized feeding ecology, such as large felids, and the upper canine morphology is both canid‐like and felid‐like. The giant panda is the most divergent species, and its short, blunt, and cone‐like canines appear well adapted for tearing into bamboo. The almost equally herbivorous spectacled bear has a less derived canine morphology. The large canines of the sun bear are divergent from other ursine ursids, and may be an adaptation for tearing open tree trunks in search of insects. Discriminant Analysis is successful in separating ursid species on the basis of canine morphology, but the canines of ursine ursids, and also of the spectacled bear, show greater resemblance among the species than the marked differences in feeding ecology would suggest. This could be in part due to a short evolutionary history, and in part due to canines not having been subjected to much evolutionary selection as has been the case among other large carnivores, such as large felids. Ursids are probably evolutionarily and ecologically successful due to physical size and strength rather than a derived craniodental anatomy.

Polar bears have the sharpest canines for tearing into thick hide and blubber while the giant panda has blunt canines for crushing bamboo.
