A16-152E2 Bore 3685.032 Mm, Heavy Duty Slewing Rings With External Gears (four-point Contact Ball)
The A16-152E2 Single-row four-point contact ball slewing bearings are widely used in rotational applications requiring the ability to withstand combined loads (axial force, radial force, and overturning moment) and demanding a compact structure and low self-weight, such as engineering machinery (truck cranes, excavators), wind power generation (yaw bearings), port machinery, photovoltaic tracking systems, robotics, and medical devices.
The A16-152E2 bearing is a Heavy Duty Slewing Rings with External Gears (four-point contact ball) with an inner diameter of 3685.032 mm , an outer diameter of 4127.9826 mm, a width of 165.1 mm. 50Mn or 42CrMo rings, chrome-alloy steel rolling mlement. Double Sealed type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
A16-152E2 bearings ( 3685.032 mm x 4127.9826 mm x 165.1 mm) have the advantages of Compact structure, lightweight, small footprint, high cost-performance ratio, and are therefore widely used in the Robots, construction machinery, wind turbines, radar antennas, and various rotary worktables.

The A16-152E2 Single-row four-point contact ball slewing bearings mainly consist of an inner ring, an outer ring, steel balls, spacers, and a sealing device. The raceways are peach-shaped or arc-shaped, and the steel balls form four-point contact with the inner and outer ring raceways. Gears can be integrated into the inner and outer rings.
Single-row four-point contact ball slewing bearings feature a low axial height and light weight due to their single-row structure. One bearing can simultaneously withstand axial loads, radial loads, and overturning moments. The four-point contact design provides high load-bearing capacity, good rigidity, and easy installation and maintenance.
