Application overview
How Koyo bearings serve Steel & Rolling Mills
Rolling mill stands, mill gearboxes, roller tables and auxiliary drives work under heavy radial loads, high temperatures, water and scale. Their bearings must carry extreme loads while running in contaminated conditions. Plant maintenance departments put an exact reference match and fast replacement during breakdowns first.
- Use multi-row cylindrical or tapered roller bearings on roll necks and heavily loaded mill shafts, and match the exact series and suffix.
- Where temperatures run high, check the heat-stabilization and clearance suffixes rather than fitting standard-clearance bearings.
- Consider spherical roller thrust bearings for heavy axial loads on screw-down and pinion stands.
- Confirm the seal and lubrication arrangement on bearings exposed to cooling water and mill scale.
