NU 336 ECM

The NU 336 ECM is a premium single row cylindrical roller bearing designed to handle heavy radial loads at high rotational speeds. Its robust construction features a machined brass cage (designated by the "M") which provides excellent guidance for the rollers, ensuring stability and reliability even under demanding operating conditions. This bearing is a non-locating type, meaning it accommodates axial displacement of the shaft relative to the housing in both directions, making it an ideal choice for applications where thermal expansion and contraction are factors. The separable inner ring design simplifies mounting and dismounting procedures, streamlining maintenance and reducing downtime.

A key advantage of the NU 336 ECM lies in its optimized internal design and enhanced roller-to-raceway contact. The "EC" designation signifies an improved internal geometry that increases the bearing's load-carrying capacity and extends its service life. The logarithmic profile of the rollers minimizes edge stresses, which in turn reduces friction and operating temperatures. This leads to greater energy efficiency and allows the bearing to perform reliably for longer periods, even in continuous operation. The superior surface finish on all contact surfaces further enhances lubricant film formation, crucial for preventing metal-to-metal contact and premature wear.

Thanks to its combination of high load capacity, accommodation for axial displacement, and long operational life, the NU 336 ECM is a versatile bearing solution for a wide array of heavy industrial equipment. It is frequently specified for use in applications such as industrial gearboxes, pumps and compressors, electric motors, and machinery in the mining and construction sectors. For engineers and maintenance professionals, the NU 336 ECM represents a dependable component that enhances machine reliability, improves efficiency, and offers a lower total cost of ownership through its durable and low-maintenance design.
