What's the reason of cross roller bearing temperature raise?

Cross cylindrical roller bearing high temperature is a common fault of rotating equipment, which will reduce the bearing service life and increase the maintenance cost. When the temperature rises fast and the temperature exceeds the standard, it is easy to cause unplanned shutdown or load reduction of the unit, which has a great impact on economic benefits.Therefore, it is the guarantee of the continuous safe operation of the equipment to quickly determine the cause of the fault and take proper measures to solve it.

The reasons for cross cylindrical roller bearings temperature rise are as follows:

First: Does the quality of the lubricant deteriorate?If the lubricating oil viscosity is large, the precision cross roller bearing temperature will increase.

What's the slewing bearing performance and characteristics?

Slewing ring bearing is a kind of large bearing which can bear the combined load of large axial load, radial load and overturning moment at the same time.Generally, the swing bearing itself is equipped with mounting holes, lubricating oil and sealing devices, which can meet the different demands of various hosts working under various working conditions.On the other hand, the turntable bearing itself has the compact structure characteristics, easy to guide rotation, simple installation and easy maintenance, which is widely used in large slewing ring such as lifting transport machinery, extractors, construction machinery, port machinery, wind power generation, medical equipment, radar and missile launcher.

Swing ring usually consists of four parts, including inner ring, outer ring, rolling body and isolation block.As the core part adopts slewing bearing, it can bear axial force and radial force at the same time.It has many forms, but its structure is basically the same.
