High Speed Gcr15 Pillow Block Ball Bearings UCF306 30*125*44 For Replace / Repair

High Speed GCr15 Pillow Block Ball Bearings UCF306 seamlessly replaces equivalent metric-spec bearings (e.g., SKF UCF306, NSK UCF306). 40Cr alloy steel set screws (HRC 86-89)—1 HRC higher than UCF305 and 1 HRC lower than UCF307—with anti-loosening washers ensure firm fit with 30mm metric shafts, avoiding slippage under torque up to 1,400N·m—200N·m higher than UCF305 and 250N·m lower than UCF307. This makes it perfect for batch procurement by light-industry plants (e.g., food machinery factories, small electrical appliance assembly equipment manufacturers) with medium-capacity production lines, supporting transmission systems with load capacity up to 3,200kg—14.3% higher than UCF305 and 13.5% lower than UCF307—designed for 18-hour daily medium-duty industrial cycles.
