Timken 416294 Oil Seal

The Timken National 416294 oil seal is a radial shaft seal engineered to retain lubricant and resist contamination in heavy-duty industrial rotating equipment, including gearboxes, pumps, electric motors, conveyors, and compressors, helping prevent lubricant leakage and extend bearing service life during preventive maintenance or equipment repair. It uses a Type 41 multi-lip with spring design and nitrile (NBR) lip material, sized for a 3.375 in shaft (85.725 mm) with an outside diameter of 4.254 in (108.052 mm), a housing bore of 4.249 in (107.925 mm), and an overall width of 0.500 in (12.700 mm), all housed in a steel case with inner case and Redi-Coat finish. The seal is rated for a maximum shaft surface speed of 3000 ft/min, with misalignment tolerance of 0.015 in at 800 rpm and 0.010 in at 4200 rpm, and an operating temperature range from -40°F to 225°F (-40°C to 107°C), making it suitable for demanding industrial environments. Common replacements include SKF 416294, CR 416294, and National 416294.
