Designed with four matched tapered roller and raceway assemblies, they deliver exceptional rigidity and high load-bearing performance, making them ideal for heavy machinery applications like rolling mill stands, calenders, and large gearboxes.
These bearings feature optimized internal geometry for reduced friction and heat generation, ensuring stable operation even under high-speed and heavy-load conditions. They are available in various configurations (e.g., separable or non-separable designs) to suit diverse installation requirements, and can be customized with special coatings or lubrication for enhanced durability in harsh environments.
