The single-row four-point contact ball slewing bearing consists of two raceway rings (an inner ring and an outer ring). It features a compact structure and light weight, with the rolling elements making four-point contact with the arc-shaped raceways, allowing it to simultaneously withstand axial loads, radial loads, and tilting moments.
It is suitable for rotary conveyors, welding manipulators, small and medium-sized cranes, excavators, and other types of construction machinery.
Series HS products feature an optimized design that delivers higher load-bearing capacity and a longer service life, making them well suited to heavy-duty construction machinery and harsh operating environments.
Series Q is our economy line, offering improved cost-effectiveness while preserving essential performance, making it a strong fit for cost-sensitive applications.
n1 denotes the number of lubrication holes. Based on your equipment’s maintenance requirements, we can specify the exact position of each lubrication hole (grease fitting M10×1, per standards JB/T 7940.1 through JB/T 7940.2).
n-∅ denotes the mounting holes, which are plain (unthreaded) by default. These can be converted to threaded holes to suit your mounting arrangement (thread diameter M, thread depth 2M).
Standard products are supplied with unspecified (free) tolerances on both the inner and outer diameters. If your host equipment requires a specific fit with the slewing bearing, please provide your exact requirements so we can arrange custom production for you.
We can provide special structural designs, dimensional specifications, material requirements (such as low-temperature or corrosion resistance), higher precision grades, and any other non-standard customization services.
