The results have been applied to Baosteel 2050 hot rolling mill, effectively solving the problem of short life and burning loss of rolling mill combined bearing. The comparison test on site shows that the device reduces the original offset coefficient of the combined bearing to 1.04 from 1.47.
Comparative testing with bearings made from standard materials shows that when running with contaminated lubricant, STF bearings achieve a service life that is around ten times longer. In practice, service lives of up to three times the usual service life can be expected.
Jun. 23, 2022. Analysis of the failure of the guide roller bearing in the finishing mill guiding device shows that the main failure forms are wear, fracture, burnout and contact fatigue. The main reason …
After installation, it was quickly demonstrated that the STF tapered roller bearings with Sealed Clean seals achieved a significantly longer service life than the …
Optimal solutions can be found when bearing manufacturers and users work closely together. This is demonstrated by a project to optimise work roll bearings, which NSK carried out in cooperation with the maintenance department of a European hot rolling mill. Hot wide strip rolling mills process red-hot slabs into steel strip using a high rolling ...

(5) Too much or too little grease in the rolling bearing of the ball mill will form rolling elements. Stirring the grease will generate heat, and the heat is not easy to disperse. If the lubrication is too little or poor, add enough oil according to the regulations, generally 1/3 ~ 1/2 of the bearing clearance.
Roll Repair. Reclaim roll life through Xtek's Roll Reconditioning and Repair Services. The bearing journals of forged steel work rolls often become worn below blueprint specifications after many extended campaigns in the mill.
ε = life factor, ε = 3 for ball bearings, and ε = 10/3 for roller bearings. It is known that the basic nominal life of the bearing is one million turns (1 × 106r) as the basic nominal dynamic load is Cr, PεL10 = 1 x Crε Thus, the equation of …
