Specification :

THB Single row four point contact slewing ring
is consisted of two rings ( one inner ring and one outer ring.) It has compact
structure and light weight. As its balls are four point contacted with the
raceway, the slewing ring can take axial load, radial road, and tilting moment
at the same time. It is used widely for the application of rotary welding
machinery, medium and small series crane and excavators etc.

Our slewing
ring for the excavator slewing ring types will be updated from time to
time.
