Product Item:HXST-404
Model: Double volleyball slewing bearing (02 series)
Construction: Features two rows of ball bearings arranged in a specific pattern to provide stability and support during rotation
Material: Typically made from high-quality materials such as steel to ensure strength, durability, and resistance to wear
Installation: Proper mounting and alignment are crucial for optimal performance and longevity of the slewing bearing
Structural characteristics, performance, scope of application
The double volley ball slewing bearing has three races, and the steel balls and spacers can be directly discharged into the upper and lower raceways. According to the stress conditions, two rows of steel balls with different diameters are arranged. This open assembly is very convenient. The bearing angles of the upper and lower arc raceways are 90 °, which can withstand large axial forces and tipping moments. When the radial force is greater than 0.1 times the axial force, the raceway must be specially designed. The double volley ball slewing bearing has relatively large axial and radial dimensions, and its structure is tight. Particularly suitable for tower cranes, truck cranes and other loading and unloading machinery that require medium or larger diameters.
Note:
1. n1 is the number of lubricating oil holes, evenly distributed: oil cup M10 × 1 JB / T7940.1-TB7940.2.
2. The mounting hole n-Φ can be changed to a screw hole; the tooth width b can be changed to H-h.
