BT4-8049 G/HA1

The BT4-8049 G/HA1 is a high-performance four-row tapered roller bearing engineered for extreme operational demands. Specifically designed as a work roll bearing for rolling mill applications, its dimensions and internal geometry are optimized to handle immense combined loads. This bearing is built to manage the heavy radial forces and axial thrust loads that are characteristic of metal forming processes. The four-row configuration provides exceptional load-carrying capacity and rigidity within a compact design, ensuring the stability and precision required in heavy industrial machinery.

A key advantage of the BT4-8049 G/HA1 lies in its advanced material and design features. The "HA1" suffix indicates that the bearing rings and rollers are manufactured from case-hardened steel. This specialized heat treatment creates an extremely hard surface for superior wear and fatigue resistance while maintaining a tougher, more ductile core that can withstand high shock loads without fracturing. This results in a significantly extended service life even under the most punishing conditions. Furthermore, the internal design is optimized to reduce friction and heat generation, contributing to smoother operation and lower energy costs.

Primarily utilized in the demanding environment of steel and non-ferrous rolling mills, the BT4-8049 G/HA1 provides a reliable and long-lasting solution. Its ability to handle bidirectional axial loads makes it suitable for various stand positions. The design also allows for efficient lubrication and sealing arrangements, which are critical for protecting the bearing from contaminants like water and scale, common in mill environments. The overall construction ensures minimal downtime for maintenance, directly supporting continuous production cycles and maximizing operational efficiency.
