Double-row Cylindrical Roller Structure：The NNU49 double-row cylindrical roller bearings series features a double-row cylindrical roller arrangement. The rollers make line contact with the raceway, enabling them to efficiently carry radial loads and possess a certain axial load-bearing capacity, thus being able to handle complex force conditions of equipment.
High-precision Ring Machining：The inner and outer rings have undergone multiple precise processes such as fine forging, grinding, and heat treatment. The dimensional accuracy is controlled within a very small range, the surface is smooth and has high hardness, and it fits closely with the rollers to ensure the stable operation of the bearing.

Application

The bearings can be used in the following industries

Machine Tool Industry：Widely used in the spindle support of large CNC lathes and milling machines, ensuring machining accuracy and meeting the requirements for processing precision parts.
Metallurgical Field：In rolling mills and forging equipment, it bears high temperature, heavy loads, and frequent impacts, ensuring the continuous and stable production process.
Mining Extraction：Equipment such as crushers and ball mills rely on it for stable operation, coping with harsh environments and high-intensity operations, and improving mining efficiency.
