Slewing bearing lubrication and maintenance methods
  • 2017-12-12 03:52:00

1. A small amount of No. 2 extreme pressure lithium-based lubricating grease (GB/T7324-1994) is coated on the track of the slewing bearing when it leaves the factory. When it is put into use, it should be filled with new lubricating grease according to different operating conditions.2. The raceway of the slewing bearing should be filled with lubricating...

Four categories of slewing bearing materials
  • 2017-10-25 06:56:00

1. Under normal circumstances, 50Mn is used for the slewing bearing ring, but sometimes 42CrMo is used to meet the needs of the host in special applications.2. GCr15SiMn is generally used for rolling elements.3. The type of retainer has different structural types such as integral type, segment type, isolation block type, etc. The integral or segmented r...

Low temperature bearings
  • 2017-09-14 08:01:00

1. Bearings whose working temperature is lower than -60℃ are low temperature bearings. Mainly used in various liquid pumps, such as liquefied natural gas pumps, liquid nitrogen (hydrogen, oxygen) pumps, butane pumps, liquid pumps for rocket missiles, spacecraft, etc. Commonly used low-temperature bearing structures are mostly single-row deep groove ball...

Load capacity and friction of spherical roller bearings
  • 2017-07-11 11:02:00

The load carrying capacity of spherical roller bearings is mainly used to bear radial loads. But it can also carry a certain amount of axial load in either direction. When the radial clearance of the bearing increases within a certain range, this bearing has the characteristics of an angular contact ball bearing, and can also bear a large axial load.Com...

Judgment criteria for abnormal bearing temperature rise
  • 2017-06-15 01:06:00

The temperature of the bearing can generally be inferred from the outdoor temperature of the bearing. If the oil hole is used, the temperature of the outer ring of the bearing can be directly measured. The temperature of the bearing starts to rise slowly with the operation of the bearing, and reaches a stable state after 1 to 2 hours. The normal tempera...
