Product Overview: The NU 318 Cylindrical Roller Bearing
The NU 318 bearing is a robust and essential component in the NU Series of Cylindrical Roller Bearings, specifically part of our NU 300 Series. Measuring 90mm in bore diameter, 190mm in outer diameter, and 43mm in thickness, this bearing is engineered to accommodate heavy radial loads and high speeds. Its design features an outer ring with two integral flanges and an inner ring without flanges, allowing for axial displacement of the shaft relative to the housing. This characteristic makes the NU 318 ideal for applications where thermal expansion or contraction might occur, or where axial movement needs to be compensated without inducing stress on other components.
As a leading supplier of industrial bearings and mechanical parts, we ensure that our NU 318 bearings are manufactured to rigorous industry standards. These bearings are renowned for their high rigidity, precision, and long service life, making them suitable for a wide array of demanding industrial environments. Their separable components facilitate easier mounting and dismounting, which simplifies maintenance and reduces downtime.
