PB 6 

The PB 6 is a miniature spherical plain bearing designed for small-shaft applications where compact size and smooth rotation with angular accommodation are required. With a 6 mm bore, 18 mm outer diameter, and 9 mm width, PB 6 is ideal for very compact linkages, small actuators, or light mechanical pivots. It supports a dynamic radial load of approximately 4.3 kN and a static radial load of around 9.8 kN, sufficient for light-load conditions or delicate link mechanisms. The bearing’s hardened inner spherical ring and durable outer ring provide reliable sliding contact and resistance to wear, even during repeated cycles of motion. PB 6 is especially useful for small-scale automation, mechanical linkages, or lightweight pivot joints where space is limited but smooth, stable movement is critical.
