The NU321MYC3 cylindrical roller bearing features a 105 mm bore diameter, 225 mm outer diameter, and 49 mm width, designed for high radial load capacity and durability. It has a single row of cylindrical rollers housed in a machined brass cage, which reduces friction and supports higher speeds. This bearing type includes two flanges on the outer ring and none on the inner ring, allowing axial displacement in both directions, ideal for accommodating thermal expansion. With a dynamic load rating of 340,000 N and static load rating of 385,000 N, it suits heavy-duty applications requiring reliable, smooth operation.
