PB 18 | Spherical Plain Bearing (Rod End Type Insert)

PB 18 

The PB 18 is a robust spherical plain bearing designed to accommodate both rotational and angular motion while supporting substantial radial loads. With an 18 mm bore, 42 mm outer diameter, and 23 mm overall width, it offers a compact yet sturdy profile suitable for mechanical linkages, pivots, suspension arms, and oscillating components. Its spherical inner design allows tilting or angular misalignment up to approximately 15°, making PB 18 especially useful in assemblies where alignment varies during motion. Constructed from high-carbon steel and bearing-grade materials, PB 18 provides high strength and durability under demanding operational conditions. With a dynamic load capacity of around 25,700 N, this bearing is ideal for heavy-duty applications where reliability, smooth articulation, and resistance to wear are required, such as in agricultural machinery, industrial linkages, hydraulic systems, and mechanical suspension components.
