What are the used screws requirements in building mechanical slewing bearings?

It is well known that slewing bearings are used in many fields and are also  one of the most important construction machinery parts.To ensure the safe  operation of slewing ring, the whole process of production and installation  of slewing bearings is often involved.FRB Bearings will introduce what are  the used screws requirements in building mechanical slewing bearings?, come  together to understand!

1. Requirements for bolts used:
The size of bolts used shall conform to the regulations of GB/ T5782-2000  and GB/ T5783-2000, and the strength grade shall not be lower than the 8.8  level specified in GB/ T3098.1-2000, and the proper strength grade shall be  selected according to the bearing capacity.So make sure you choose the  right bolt.That's how it works.

2. Operating standard of nuts:
The size of nuts shall comply with the provisions of GB/ T6170-2000 and GB/  T6175-2000, and their mechanical properties shall comply with the  provisions of GB/ T3098.2-2000.Therefore, the standard of nut use is also  very strict, which should be noted.

How is the slewing bearing sealed at high temperature?

Slewing bearing is an important part of mechanical equipment, which is not only used in engineering machinery, but also widely used in port, military, wharf and other fields.But now many friends are asking about the slewing bearing at high temperature if the bearing is sealed.Here, FRB BEARINGS are simple to talk about.

The slewing bearing is mainly composed of upper ring, lower ring and a full complement ball.These two single row and double row designs, as well as the convenience of pre-drilled mounting holes.In real life, some bearings are only tightened at the fixed blade end, some are tightened at both the fixed blade end and the moving blade end, the way of tightening is cylinder type, there are also institutional linkage.Under the working environment of heavy load and low speed, the bearing is sealed by rubber sealing ring or labyrinth seal.
