How to Manage Hot Bearings in Your Plant

Cooling the housing of a hot bearing can remove bearing clearances when the outer race cools, as the inner race will still be hot. The reduction in radial internal clearance will increase bearing friction and drastically reduce bearing life. The potential of catastrophic failure is also increased.

P. Kucsera et al. Hot Rolling Mill HGC Thickness Control Improvement – 98 – Another way to determine the thermal expansion of the work roll is the modelling of the heat transfer between the work rolls and the strip. This depends on the roll speed, strip thickness, the properties of the strip, roll gap, contact time and cooling parameters.

Rolling (metalworking) - Wikipedia

Hot-rolled metals generally have little directionality in their mechanical properties or deformation-induced residual stresses.However, in certain instances non-metallic inclusions will impart some directionality and workpieces less than 20 mm (0.79 in) thick often have some directional properties. Non-uniform cooling will induce a lot of residual stresses, which usually occurs in …
