First, whether the distribution of bearing load is reasonableBearing assemblies in a lack of a consistent support surface, a common mistake during the design phase of the support structure is that the slewing bearing assumes that the support structure is sufficiently rigid.Second, is the bolt strong enough?The main guarantee is to choose the right slewi...

First of all, we must do a good job in the inspection and maintenance of the slewing bearing. First use the slewing bearing for 100 working hours to check the bolt moment moment. Assuming that about 10% of the bolts are loose, check again after the 200th working hour. After that, check every 500 working hours; reduce the check distance for extreme loads...

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...

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...

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...
