How to store the slewing bearing is not used for a long time?

Many manufacturers will buy a lot of swing bearings at one time to ensure adequate inventory of the warehouse, but the slewing ring will not be used for a long time, rust will occur, resulting in the slewing bearing can not be used normally. Today, we will explain how to store the slewing bearing that is not used for a long time.

Long-term storage conditions and items of slewing bearing:
1.The warehouse temperature: slewing bearing are coated with anti-rust oil before they go out, the temperature too low or too high will lead to rust-proof oil metamorphism, room temperature should be controlled in 0 to 25 ℃;

FRB Bearings Slewing bearing application fields

The slewing bearing has to be adopted when,in a machinery or in mechanical plant,a structural part must rotate opposed to another part,along a fixed axis,ensuring the axial and radial link between the two parts.The slewing bearing,with the maximum stiffness offered by its design,must bear and transmit the operative loads of the structure it is linked to,and also it must guarantee the required motion precision,the respect of operational parameters,and the required lifetime.

It is evident how the slewing bearing is a fundamental component and its choice must be done according to specific technical studies.FRB Bearings technical staff can assist your company in the choice of the suitable bearing.

Common application are:
excavators
concrete pumps
boomlift,manlift
crane truck
civil and harbour crane
compactors
wind turbines
radar
manipulators
filling carousels
rotary tables
demolitions shears
wrapping machines
forest machines

What is the function of the cross roller bearing in the crane rotary mechanism?

The cross roller bearing of the crane plays the role of connecting the carriage and chassis parts in the rotary mechanism, and supports the whole rotating part of the crane.If the damage of steel ball slewing bearing, rolling wear will affect the work of slewing mechanism, serious when slewing mechanism will be rotary, the phenomenon such as noise, heavy rotary hydraulic system pressure will exceed the rating at the same time.When the lifting and unloading are stopped, the vibration of the slewing bearing down or upward will be too large, indicating that the clearance volume of the rotary support is seriously exceeded.At this time, the rotary support should be repaired or replaced.The general cause of mechanical failure is the lack of maintenance and improper use of cross roller bearing.
