Connecting rod needle roller bearing is joint bearings with rod end or mounted on the rod end, which belongs to a class of joint bearings.
Connecting needle roller bearing EH series (enhanced);Rod end joint bearing EG series (enhanced);Inch dimension rod end plain bearings normal series (dimension series code Z);Connecting rod needle roller bearing JK series (size series code for JK).Its structural material code and clearance group code are similar to joint bearings.
Connecting needle roller bearing are mainly used for supporting parts with low concentricity requirements, high pressure on the working surface and slow swing and rotary motion.
Rod-end plain bearings belong to sliding bearings, with wear-resistant non-metallic material lubrication type, and oil channel lubrication type.
Connecting needle roller bearing, rod end joint bearing vibration is sensitive to damage, such as peeling, indentation, rust, crack and wear will be reflected in the rod end joint bearing vibration measurement, therefore, through the use of special rod end joint bearing vibration tester (frequency analyzer, etc.) can measure the size of the vibration, through frequency points cannot deduce the abnormal situation.
The temperature of the connecting rod needle roller bearing can generally be inferred by the temperature outside the rod-end plain bearing. If the oil hole can be used to directly measure the temperature of the outer ring of the rod-end plain bearing, it is more appropriate.
Usually, the temperature of the connecting rod needle roller bearing to rise slowly with the operation of the connecting rod needle roller bearing, and reaches a stable state after 1-2 hours.The normal temperature of rod-end plain bearings is different due to the heat capacity, heat loss, speed and load of the machine.
