Product Description
EP-PB12 construction and application notes
EP-PB12 is the 12 mm-bore model in the PB Bronze-Lined family. Its nominal envelope is d 12 mm × D 30 mm with B 16 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-PB12, that construction is paired with a 12 mm bore, 30 mm outside diameter, 16 mm overall width, 13 kN dynamic rating and 13° catalogue articulation value.
For EP-PB12, 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-PB12, start the fit review from its 12 mm bore and 30 mm outside diameter, then check how the 16 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-PB12 in the joint
For EP-PB12, before treating this model as a repeat order, compare the installed joint with the current dimensional row. Compare the complete envelope with the removed part; a matching bore by itself does not establish the correct housing fit. Check how often the joint moves, how far it articulates and whether the installed bearing can actually be reached for maintenance. For MRO replacement, send the removed bearing code, housing condition and pin measurement rather than only the nominal bore.
