Industry-Tailored Solutions

🏭 Metallurgy & Steel Production

Survive scorching environments with our high-temperature series featuring ceramic-coated cages and 350°C-rated steel. Ideal for continuous casting rollers and blast furnace conveyors.

🚢 Port Machinery & Cranes

Prevent corrosion-induced failures in saltwater environments. Our impact-resistant series uses 20Cr2Ni4A alloy rollers and reinforced ribs to absorb shock loads from heavy container handling.

🏥 Medical Imaging Systems

Achieve whisper-quiet operation (<20dB) with ultra-precision P4-grade bearings. ISO cleanroom-certified designs ensure smooth rotation for MRI scanners and CT gantries.
