Min. Order:1 Piece

The VA 160302 N 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 VA 160302 N bearing is a Four point contact bearing, slewing ring, external teeth with an inner diameter of 238 mm , an outer diameter of 384 mm, a width of 32 mm. It typically uses P5, P6, P0 grade precision tolerances and 50Mn,42CrMo rings, GCr15 rolling mlement. It primarily bears axial, radial and tilting moment loads, Its dynamic radial rated load is approximately 123000 N, its static radial rated load is approximately 270000 N. Its dynamic axial rated load is approximately 136000 N, its static axial rated load is approximately 590000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

Designation Breakdown

The VA 160302 N 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.
