NJ 336 ECM

The NJ 336 ECM is a high-capacity single row cylindrical roller bearing specifically developed to handle substantial radial forces while accommodating high-speed rotations. Measuring 180x380x75mm, this unit features the classic NJ design, incorporating two fixed ribs on the outer ring and a single rib on the inner ring. This configuration is essential for applications requiring one-directional axial location, effectively managing shaft expansion without sacrificing performance. The "ECM" designation highlights the integration of an enhanced internal design with a solid brass cage, which is window-type and land-riding, providing exceptional durability and vibration resistance in volatile environments.

From a performance standpoint, the NJ 336 ECM is engineered to reduce internal friction, which directly translates to cooler operating temperatures and a prolonged grease life. Its optimized roller-to-raceway contact ensures an even distribution of stress, preventing premature fatigue and extending the overall service life of the machine. Because the bearing components are separable, engineers find it much easier to perform inspections and mountings, particularly in large-scale industrial setups like heavy-duty compressors, mining equipment, and traction motors. By choosing this brass-caged variant, operators gain a high-reliability component capable of withstanding the rigors of continuous 24/7 production cycles.
