Product Description
FCDP88124450 is a heavy-duty FCDP-series four-row cylindrical roller bearing with standard dimensions of inner diameter 487mm, outer diameter 620mm, width 450mm, and net weight 436kg. Manufactured by Wafangdian Jinyu Bearing Manufacturing Co., Ltd., this bearing adopts high-carbon chromium bearing steel GCr15SiMn compliant with GB/T18254 national standard, equipped with matched 20# steel and 40# steel structural accessories, featuring reliable material performance and strong wear resistance.
This precision P0 grade bearing is configured with C3 standard radial clearance (basic radial clearance range: 0.21mm-0.31mm) and optimized internal structural design. It has a dynamic load rating (Cr) of 6890kN and a static load rating (Cor) of 19400kN, with axial clearance between rollers and washers controlled at 1.5mm. The four-row roller structure realizes uniform load distribution, effectively bearing heavy radial load and impact load, maintaining stable operation in low-speed and continuous working conditions. Widely applicable to various heavy-duty metallurgical rolling mill equipment, it is a core supporting component for hot strip mills, plate mills and slab mills.
