Silindrical rola bearings

Awọn NU318 EM jẹ iru kan ti yiyi rola ti nso. Eyi ni didenukole ti awọn pato ati awọn ẹya rẹ:

1. Ti nso Iru:

• Kii ṣe: This indicates the type of cylindrical roller bearing. NU-type bearings have two fixed ribs on the outer ring and no ribs on the inner ring, allowing the inner ring to move axially relative to the outer ring. This design is suitable for applications where axial displacement needs to be accommodated.

2. Awọn iwọn:

• Awọn 318 in the bearing code refers to its size. The dimensions for NU318 are:
  • Giga ila opin (d): 90 mm
  • Iwọn ila opin (D): 190 mm
  • Ìbú (B): 43 mm

3. Suffix:

• EM: Suffix yii tọkasi apẹrẹ inu inu ati ohun elo ẹyẹ. Fun idi eyi:
  • E: Optimized internal design for higher load capacity.
  • M: Indicates that the cage is made of machined brass (ri to idẹ ẹyẹ), which is suitable for high-speed applications and provides better lubrication retention.

4. Agbara fifuye:

• NU318 EM bearings are designed to handle high radial loads due to their cylindrical roller design. They are not suitable for axial loads because of the NU design (no ribs on the inner ring).

5. Awọn ohun elo:

• NU-type cylindrical roller bearings are commonly used in applications where high radial loads and axial displacement are present, bi eleyi:
  • Awọn ẹrọ itanna
  • Awọn apoti
  • Ẹrọ ile-iṣẹ
  • Awọn ifa
  • Paper manufacturing equipment

6. Lubrication:

• Proper lubrication is essential for optimal performance. Grease or oil lubrication can be used depending on the application and operating conditions.

7. Mounting and Maintenance:

• NU318 EM bearings require precise mounting to ensure proper alignment and load distribution. Regular maintenance, including lubrication and inspection, is necessary to extend the bearing’s lifespan.
