BC4-0117

The BC4-0117 is a specialized four-row cylindrical roller bearing designed to excel in demanding industrial environments. With an inner diameter of 220 mm, an outer diameter of 310 mm, and a width of 192 mm, this bearing offers a substantial contact area, enabling it to support exceptionally high radial loads. Its robust construction ensures reliability under the intense pressures and high speeds commonly found in heavy machinery. The separable design, featuring an inner ring without flanges, allows for easier mounting, dismounting, and maintenance inspections by permitting the inner and outer rings to be fitted independently.

Engineered for superior performance, the BC4-0117 bearing incorporates several key design features that deliver significant operational advantages. The four rows of rollers provide maximum radial load-carrying capacity and high stiffness, which is critical for maintaining precision in applications like rolling mills. The internal design minimizes friction, which translates to lower operating temperatures and reduced energy consumption. This low-friction characteristic, combined with enhanced surface finishes on the rollers and raceways, promotes the formation of a hydrodynamic lubricant film, extending the bearing's service life and ensuring reliable operation over long periods.

The unique characteristics of the BC4-0117 make it an ideal choice for the work roll and backup roll positions in metal rolling mills. Its ability to accommodate very heavy radial loads and allow for axial displacement between the inner and outer rings is essential in this environment, where thermal expansion of the rolls is common. The bearing's durability and long service life contribute to increased uptime and reduced maintenance costs, providing a lower total cost of ownership for steel, aluminum, and other metal-forming operations. Its design ensures consistent performance where precision and reliability are paramount.
