When the Kamaz bearing china suppliers disassembles the bearing for inspection, it first records the appearance by photography and other methods. Also, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing.
a. The cleaning of the bearing is divided into rough cleaning and fine cleaning, and a metal grid frame can be placed at the bottom of the container used.
b. During rough cleaning, use a brush in the oil to remove grease or stickies. At this time, if the bearing is rotated in oil, be careful that the rolling surface will be damaged by foreign objects.
c. During fine cleaning, turn the bearing slowly in the oil, which must be done carefully.
The cleaning agent usually used is neutral water-free diesel or kerosene, and sometimes warm lye is used as needed. No matter what kind of cleaning agent is used, it must be filtered frequently to keep it clean.
After cleaning, apply anti-rust oil or anti-rust grease to the bearing immediately.

application

Large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and lifting and transporting machinery, etc.

Accuracy class

Cylindrical roller bearings can be divided into PO, P6, P5, P4, P2 according to the accuracy grade. The accuracy grade is sorted from low to high.

features

  1. The rollers and the raceway are in line contact or trimmed line contact, with large radial bearing capacity, suitable for bearing heavy loads and impact loads.
  2. The friction coefficient is small, suitable for high speed, and the limit speed is close to that of deep groove ball bearings.
  3. N type and NU type can move axially, can adapt to the change of the relative position between the shaft and the shell caused by thermal expansion or installation error, and can be used as free end support.
  4. The processing requirements for the shaft or seat hole are relatively high. After the bearing is installed, the relative deflection of the axis of the outer ring must be strictly controlled to avoid contact stress concentration.
  5. The inner or outer ring can be separated for easy installation and removal.
