34 0841 01 Bore 772 Mm, Square Sections Ball Slewing Rings With External Gear With Spacers
The 34 0841 01 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 34 0841 01 bearing is a Square sections ball slewing rings with External gear with spacers with an inner diameter of 772 mm , an outer diameter of 950 mm, a width of 56 mm. It typically uses P0, P6, P5 grade precision tolerances and XC45 rings, GCr15 rolling mlement. It primarily bears axial, radial and tilting moment loads, its static radial rated load is approximately 840000 N. Double sealed type, NBR (Nitrile Butadiene Rubber). together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
34 0841 01 bearings ( 772 mm x 950 mm x 56 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 34 0841 01 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.
