دی NU317 EM is a type of cylindrical roller bearing. Here’s a breakdown of its specifications and features:

1. Bearing Type: NU317 EM

NU NU: Indicates the bearing type. “NU NU” means it is a cylindrical roller bearing with two flanges on the outer ring and no flanges on the inner ring. This design allows for axial displacement of the shaft relative to the housing, making it suitable for applications where thermal expansion or misalignment might occur.
317: Specifies the size of the bearing. دی “317” corresponds to the bore diameter, outer diameter, and width of the bearing.
EM: This suffix typically indicates the bearing’s internal design and cage material. “EM” often refers to a reinforced cage design made of machined brass (solid brass cage), which provides higher strength and durability, especially in high-speed or high-temperature applications.

2. ابعاد (typical for NU317):

Bore Diameter (d): 85 ملی میٹر
Outer Diameter (D): 180 ملی میٹر
چوڑائی (B): 41 ملی میٹر

3. Key Features:

High Radial Load Capacity: Cylindrical roller bearings are designed to handle high radial loads.
Axial Displacement: The NU design allows for free axial movement of the shaft, making it suitable for applications with thermal expansion.
Solid Brass Cage (EM): The machined brass cage provides better performance in high-speed or high-temperature environments compared to stamped steel or polymer cages.
Precision Engineering: Suitable for applications requiring high precision and reliability.

4. Applications:

Industrial Machinery: Used in gearboxes, pumps, and electric motors.
Heavy Equipment: Suitable for construction and mining equipment.
Paper and Steel Mills: Commonly used in rolling mills and other heavy industrial applications.
High-Speed Applications: The EM cage design makes it suitable for high-speed operations.

5. Advantages of NU317 EM:

High load-carrying capacity.
Accommodates axial displacement.
Durable brass cage for enhanced performance.
Suitable for high-speed and high-temperature environments.

6. Equivalent Bearings:

Different manufacturers may have their own designations for the same bearing. For example:
- SKF: NU317 ECM
- FAG: NU317 E.TVP2
- NSK: NU317 EM
