SKF UJ334 633 RETN 1790 2HU3 Universal Joint

SKF UJ334 is a heavy-duty universal joint used to connect driveline shafts and transmit torque through angular misalignment in industrial and automotive applications. Designed as part of SKF's crucetas family, it features forged steel cross and cups, large grease reservoirs at the journal ends, a nitrile triple‑lip seal shielded by metal, a check valve at the journal ends for grease retention, and a dual-greaser arrangement to support maintenance. It is pre-lubricated with high-temperature grease to help extend service life. SKF cross-reference materials associate UJ334 with the 1710-series drive components and CP280X cross references (5-0280X), reflecting compatibility with common heavy-duty driveline assemblies.
