NA59 series

The NA59 series is a single row fully loaded needle roller bearing with an inner ring. The inner ring is integrated with dual gear edges, and the outer ring is equipped with dual gear edges and a cage. The full needle arrangement has no cage spacing, pure radial bearing, and ultra compact radial section. It is suitable for industrial scenarios with low-speed heavy load and limited radial space. It is commonly used for shaft end/middle support in metallurgy, mining, engineering machinery, heavy-duty gearboxes, paper machinery and other equipment.
