Four Row Cylindrical Roller Bearings

PMK Four Row Cylindrical Roller Bearings are designed for extremely high radial loads in heavy-duty and high-speed applications such as rolling mills. These bearings provide high rigidity, low friction, and consistent accuracy under continuous load conditions.

Their multi-row construction ensures excellent load distribution and long service life even in harsh environments.

Key benefits

Ultra-high radial load capacity with excellent stiffness.
Ideal for continuous, high-speed, heavy-duty operation.
Low friction for reduced energy consumption.
High dimensional accuracy for consistent performance.
Long service life under shock and vibration.

Applications

Steel rolling mills and large drive systems.
Heavy industrial gearboxes and presses.
Continuous casting and metallurgical machinery.
Paper mills and power transmission systems.
