Product Description
EP-PB25 construction and application notes
EP-PB25 is the 25 mm-bore model in the PB Bronze-Lined family. Its nominal envelope is d 25 mm × D 56 mm with B 31 mm overall width.
Outer race lined with a bronze liner, with a lubricating groove and hole in the outer ring. The steel/bronze sliding pair is intended for lubricated pivoting service, with inspection of wear, lubrication path and adjacent pin condition remaining part of maintenance. On EP-PB25, that construction is paired with a 25 mm bore, 56 mm outside diameter, 31 mm overall width, 47 kN dynamic rating and 15° catalogue articulation value.
For EP-PB25, the PB family uses a bronze-lined sliding interface and a lubricated pivoting service strategy. Its construction should be compared with PTFE-lined and steel-on-steel alternatives by considering lubrication access, motion pattern and the available joint envelope.
Installation and fit
For EP-PB25, start the fit review from its 25 mm bore and 56 mm outside diameter, then check how the 31 mm bearing width is supported by the housing shoulders. The fitting-tolerance resource includes H7 and h6 among the reference classes; final fit still depends on ring loading, housing stiffness, temperature and the machine interface.
Selection Context
How to verify EP-PB25 in the joint
For EP-PB25, this size is best reviewed from the actual pin and housing rather than from the designation alone. The dimensional check should cover bore, outside diameter and both width values so the bearing is supported as intended. If lubrication is part of the design, confirm the grease path reaches the sliding contact instead of stopping at the surrounding joint. If the housing has been repaired or re-machined, include the current bore measurement rather than relying on the original machine manual.
