NU 236 ECM

The NU 236 ECM stands as a robust solution for heavy-duty shafting systems requiring a dedicated non-locating bearing arrangement. Built with a 180mm inner diameter and a 320mm outer diameter, this single-row unit allows for unrestricted axial movement of the shaft relative to the housing, accommodating the inevitable thermal expansion found in high-torque machinery. Unlike standard variants, the ECM designation highlights a glass-fiber reinforced or machined brass cage that is precision-guided by the rollers. This design choice is critical for minimizing heat generation and ensuring consistent lubrication flow across the raceways, which directly prevents premature wear during continuous operation cycles.

Optimized for high-speed stability, the NU 236 ECM utilizes a refined internal geometry to manage extreme radial forces, boasting a dynamic load capacity of 720 kN. The separable architecture of the NU design-featuring a flangeless inner ring-streamlines the mounting process, enabling technicians to achieve interference fits on both rings without risking damage to the roller set. This makes the bearing particularly effective in sectors like power generation, mining equipment, and large-scale industrial transmissions where maintenance efficiency is as vital as mechanical strength. By distributing contact pressure via a specialized roller-to-race profile, the unit maintains operational integrity even when subjected to subtle shaft deflections or heavy impulse loads.
