China Factory High Quality Nk Series Chrome Steel Needle Roller Bearing NK 45/20 For Excavator Bearing




Product Description


Needle roller bearings:
Needle bearings are cylindrical rollers with roller bearings. The rollers are thin and long relative to their diameter. This is called a needle bearing. Although it has a small cross-section, it has a high load carrying capacity and is equipped with slender
needle bearing (roller diameter D <5mm, L / D> 2.5, L is the length of the roller), so the diameter The radial structure is compact, and its diameter size and load capacity are the same as other types of bearings, the smallest diameter, especially for supporting structures with limited radial installation dimensions.

According to different occasions, bearings without inner ring or needle and cage assembly can be used. When the surface of the journal bearing surface and the surface of the bearing seat hole directly match the outer rolling surface of the bearing, the load capacity and operation under the same performance can be ensured.
