Size range:Inter diameter 200-1500mm（Customizable within the scope）
Material: GCr15/GCr15SiMn/G20Cr2Ni4A
Type: NNU and NN series cylindrical roller bearing. The NN design has an inner ring with two ribs and an outer ring without ribs.

Double-row cylindrical roller bearings are designed to provide exceptionally high radial load capacity, enhanced rigidity, and stable performance for heavy-duty applications. Featuring two rows of precision-machined cylindrical rollers, this bearing type offers improved load distribution and greater stiffness compared to single-row designs, making it ideal for machinery that demands higher strength and reliability.
