NU 312 ECML

The NU 312 ECML is a high-performance single row cylindrical roller bearing designed to handle heavy radial loads with exceptional precision. As part of the NU design, the outer ring features two integral flanges while the inner ring is flange-less, allowing for axial displacement of the shaft relative to the housing in both directions. This makes it an ideal solution for non-locating bearing positions where thermal expansion of the shaft is a critical factor. The "EC" designation signifies an optimized internal geometry that increases load-carrying capacity and improves the formation of a lubricant film, effectively reducing friction and operating temperatures.

What sets the NU 312 ECML apart is its machined brass cage (ML), which is land-riding on the outer ring. This robust cage construction provides superior stability and durability compared to standard steel or polyamide cages, particularly in high-speed applications or environments prone to intense vibration and shock loads. With a 60mm bore and 130mm outer diameter, this bearing is engineered for longevity and reliability in demanding industrial machinery, such as large electric motors, gearboxes, and pumps. Its refined surface finish ensures quiet operation and a longer service life, even under grueling duty cycles.
