The Spherical Plain Bearing is a unique bearing designed with an intricate arrangement of ball bearings set in a cage structure that rotates freely within an outer spherical raceway on the inner ring or housing, allowing for self-lubricating, low friction motion across multiple orientations. A double row option also exists featuring two rows of balls rolling within two separate raceways resulting in greater capacity for heavy loads and tighter clearances.
