Rolling (metalworking) - Wikipedia

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

The general rule is to provide the minimum viscosity required at the expected operating temperature: 100SUS (20cst) for roller bearings and 70SUS (13cst) for ball bearings. In addition, the increased thermal expansion of the shaft must be accounted for both axially (to ensure that high thrust loads are not induced) and radially (to ensure that radial internal clearance is adequate to avoid ...

Benchtop Machine Shop: Bearing Preload

Bearing preload is critical for machine tool spindles since it keeps the spindle rigid, especially under load. It's the amount of compressive force placed on the bearings at rest, and is usually expressed in pounds force or newtons force. For example, my mill spindle has approximately 100 pounds of preload.
