Product description
The NJ2240ECMA/C3DR SKF is a double-row cylindrical roller bearing. This bearing has a particularly high radial load capacity. The design consists of a solid inner and outer ring with a double row of cylindrical rollers with a cage. The rolling elements are guided between flanges. This construction enables compact bearing arrangements with high radial stiffness and very high load capacity. The outer ring is separable from the inner ring, facilitating (dis)assembly.
The NJ2240ECMA/C3DR SKF is equipped with a cage that prevents the cylindrical rollers from coming into contact with each other. This design allows for controlled movement of the rolling elements. There is less friction than in full-complement cylindrical roller bearings. As a result, higher rotational speeds are possible, and less heat is generated.
