Product Description
EP-PB8 construction and application notes
EP-PB8 is the 8 mm-bore model in the PB Bronze-Lined family. Its nominal envelope is d 8 mm × D 22 mm with B 12 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-PB8, that construction is paired with a 8 mm bore, 22 mm outside diameter, 12 mm overall width, 6.8 kN dynamic rating and 14° catalogue articulation value.
For EP-PB8, 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-PB8, start the fit review from its 8 mm bore and 22 mm outside diameter, then check how the 12 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-PB8 in the joint
For EP-PB8, when this model is shortlisted, use the machine drawing to confirm the surrounding shoulders before looking at alternatives. Use the bore to identify the pin size, then confirm the outer ring has adequate seating across the available housing width. Describe dust, water, wash-down or other exposure because the same dimensions can exist in constructions with different sealing strategies. If the old code is incomplete, include clear photographs of both bearing faces and any readable suffixes.
Cross-Reference
