PB Spherical Plain Bearing is a documented maintenance required series for industrial linkage or pivot applications. Steel/bronze sliding pair; lubrication groove and holes. Use the main image for identification and the full product description for model-by-model dimensions and load data.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.
PB is a serviceable spherical plain bearing with a bronze liner at the sliding interface. It is aimed at compact, low-speed joints where periodic lubrication is feasible and a steel/bronze contact is desired. The catalogue covers 5–30 mm bores.

Begin with the housing and pin dimensions, then check the published load ratings and permissible tilt. A bronze-lined bearing still needs good alignment: if the pin bends or the housing clamps unevenly, load concentrates near the edge.
Keep the lubrication holes aligned with the machine’s grease path and service with clean lubricant.
GE E / GE ES 2RS is a wider-range serviceable spherical family; PHS/POS use bronze-lined spherical surfaces inside threaded rod-end housings; GE C is a compact maintenance-free PTFE option.
