NU 421 M

Designed to withstand rigorous industrial environments, the NU 421 M single row cylindrical roller bearing delivers exceptional radial load-carrying capacity and high-speed stability. Featuring a 105mm bore, a 260mm outer diameter, and a robust 60mm width, this premium component utilizes a machined brass cage (indicated by the 'M' suffix) that dramatically reduces friction and heat generation under heavy operational stress. Because the NU 421 M is engineered with two integral flanges on the outer ring and none on the inner ring, it allows for a completely separable design, simplifying mounting, dismounting, and routine maintenance checks. This specific configuration also permits unrestricted axial displacement within the bearing itself, accommodating shaft thermal expansion smoothly. Ultimately, the NU 421 M serves as a reliable, long-lasting solution for heavy-duty machinery, pumps, and gearboxes where dimensional precision and rotational integrity cannot be compromised.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
