The SD.855.25.00.B 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.
