SKF UJ334 647 ATAT 3530 1CVL3 Universal Joint

SKF UJ334 647 ATAT 3530 1CVL3 U-JOINT UNIVERSAL JOINT is a universal joint from SKF identified by the part numbers UJ334 and 647 ATAT 3530 1CVL3. In SKF’s UJ-series, this joint serves as a torque-transmitting link between shafts that do not share a fixed axis. The designation indicates compatibility with a range of yoke configurations and bearing assemblies used in precision power transmission systems. The UJ334 family is known for robust cross bearings and seals designed to sustain rotational loads across angular misalignment. This type of joint is commonly employed in driveshaft assemblies across automotive and industrial applications to accommodate shaft misalignment and facilitate smooth rotational motion. The UJ334 model number helps engineers reference the correct fitment in SKF catalogs and supplier listings when selecting a universal joint for a given drive system. For reliable, long-term performance, engineers typically consult the SKF product data sheet and installation guidelines to ensure correct cross-bearing seating, lubrication, and mating yoke sizes.
