Product Description

Achieve Micron-Level Precision: Bearings Engineered for Cold Rolling Mills

   In cold rolling, the margin for error is zero. The demand for ultra-thin, high-strength strip with impeccable surface finish requires mill equipment to operate with extreme precision, under enormous rolling forces, and at very high speeds. Any deflection, vibration, or inconsistency in the roll stand directly translates to gauge variation, strip defects, and production downtime. Our bearings are not just components; they are the foundation of your mill's precision and productivity.

  We specialize in manufacturing and supplying the highest grade bearings for every critical position in a cold rolling mill stand. Our multi-row cylindrical roller bearings for backup rolls provide maximum radial rigidity to minimize roll deflection. For work roll applications, our four-row tapered roller bearings and double row angular contact ball bearings handle combined radial and axial loads with exceptional accuracy, ensuring perfect roll positioning and consistent strip thickness profile. Advanced grinding techniques and ISO P5/P4 precision tolerances guarantee smooth, vibration-free operation at high speeds, directly contributing to superior surface quality.

  Made from specially selected and processed steel, our bearings offer superior resistance to fatigue and wear. They are designed with optimized internal geometries and surface treatments to manage the challenging lubrication conditions in a mill stand. By choosing our bearings, you invest in reduced roll chatter, extended roll life, lower energy consumption, and ultimately, higher yield of first-quality strip steel.

Features & Benefits

· Extreme Rigidity: Multi-row design and robust construction minimize elastic deformation under huge rolling forces, ensuring consistent strip gauge.
· Micron-Level Precision: Manufactured to super-precision grades (ISO P4, P5) for flawless running accuracy, critical for surface finish.
· High-Speed Capability: Precision-balanced and designed with optimized cages to reduce centrifugal forces and operating temperature.
· Superior Wear Resistance: Made from case-carburized or through-hardened bearing steel for maximum durability in contaminated oil environments.
· Simplified Maintenance: Designed for easier installation, removal, and lubrication, reducing mill downtime during roll changes.
· Enhanced Productivity: Enables higher rolling speeds, tighter tolerances, and fewer production stops, boosting overall equipment effectiveness (OEE).
