Timken National 416029N Radial Shaft Oil Seal

Timken National 416029N is a radial shaft oil seal (Type 41) engineered for heavy-duty industrial sealing tasks, providing lubricant retention and contaminant exclusion in rotating equipment such as gearboxes, pumps, electric motors, conveyors, compressors, and mining machinery. Its multi-lip ACM sealing element with a spring is housed in a steel case with an inner case, delivering reliable performance across demanding service conditions. Key dimensions include a shaft diameter of 5.750 in (146.050 mm), outside diameter of 7.881 in (200.177 mm), housing bore of 7.874 in (200.000 mm), and overall width of 0.750 in (19.050 mm); Redi-Coat treatment is present for easier installation. The seal tolerates up to 3000 ft/min shaft surface speed and accommodates misalignment of 0.015 in at 800 rpm or 0.010 in at 4200 rpm, with an operating temperature range of -20°F to 300°F (-29°C to 149°C). Commonly used for preventive maintenance, equipment repair, and seal replacement to minimize lubricant leakage and extend bearing life in heavy-duty power transmission systems. Cross references include SKF 416029N, CR 416029N, and National 416029N.
