Why Choose Us?

1. Built for Extreme Metallurgical Demands

Our bearings are crafted from high-purity chromium steel (SUJ2/GCr15) and undergo specialized heat treatment to resist thermal deformation (<0.1mm at 150°C). Perfect for:

Heavy-load zones: Roughing stands, plate mills.
High-speed applications: Finishing stands (up to 1200 RPM).
Harsh conditions: Scale, dust, and water ingress.

2. Precision Customization for Unique Needs

Whether you need a φ5000mm bearing for legacy equipment or a tapered design for tandem mills, we deliver:

Tolerances as tight as ±0.01mm (ISO P5/P6 standards).
Non-standard solutions: Split cages, hybrid ceramic rollers.
IoT-ready bearings: Embedded sensors for real-time wear monitoring.

3. Rapid Response, Global Reach

48-hour delivery for standard bearings (ID 50mm–2000mm).
15-day lead time for custom orders (φ3000mm+).
Regional hubs in the EU, North America, and Asia ensure timely support.
