Why not high temperature?

Tin based white metals generally having minimum 88% sn (tin) and rest is cd, cu, sb etc.

Tin based white metals have 4 times the load bearing characteristics and two and a half times the maximum surface speed of lead based white metals.

Bearing Materials is also known as BABBITT MATEL.

White metal have low melting point so C will be eliminated.

Tin based white bearing have low melting points, so, they can not handle high temperatures. They are most suitable to handle high pressures and loads due to their ductility, shock resistance along with low coefficient of friction.

Tin-lead and tin-copper alloys such as Babbitt metal have a low melting point that is ideal for use as solder, but these alloys also have ideal characteristics for plain bearings. Most importantly for bearings, the material should be hard and wear-resistant and have a low coefficient of friction. It must also be shock-resistant, tough and sufficiently ductile to allow for slight misalignment prior to running-in.

Tin based bearing quality having very strong and low temperature sensitive.

How can it handle the high pressure?

As we know that if pressure is high and temperature will get automatically increased.
