Detailed Product Description

Three seat-ring steel balls and spacers may be directly arranged into upper and lower raceways
Two rows of steel balls with different diameters are fitted according to load.
Load angles of both upper and lower race are 90 degrees, which enable bearing to bear large axial force from resultant movement, radial force when larger than 1/10 of axial force raceways should be specially designed.
Suitable for tower cranes which requires working diameter over medium range, mobile cranes and loading and unloading machines, as axial and radial dimension of double-row ball slewing rings are rather large and bearing construction is sturdy
