Those rams are rated @210 bar continous and 250bar intermittend.

Affordable gearpumps in smaller sizes can go up to 250 bar. But in the somewhat larger size, it's 210 bar.

By coincidence, the old maximum pressure on hydraulic pressure.

So, 2/2*3.14*210= 2640 kg of force.

@250 bar = 3150 kg.

For comparisation, Razer was around 6500 kg.
