Nachi Cylindrical Roller Bearing, Bore Dia 85 mm, Outer Dia 180 mm, Width 41 mm

The NU317MYC3 is a single-row cylindrical roller bearing featuring an 85 mm bore diameter, 180 mm outside diameter, and 41 mm width. It has two flanges on the outer ring and no flanges on the inner ring, designed for increased radial load capacity. The bearing includes a solid brass, two-piece roller-guided cage and offers larger than normal radial internal clearance (C3), enhancing performance under thermal expansion. It supports high static load ratings around 247,000 N and operates efficiently at speeds up to 3400 rpm with grease lubrication or 4000 rpm with oil. This robust bearing suits heavy-duty industrial applications requiring precision and durability.
