The Timken Company 416239 Radial Shaft Oil Seal

The Timken National 416239 radial shaft oil seal provides dependable lubricant retention and contaminant exclusion for industrial gearboxes, pumps, electric motors, conveyors, and compressors—critical in general-purpose power transmission applications. This Type 41, multi-lip with spring seal uses a nitrile (NBR) sealing element and is housed in a steel case with inner case as part of the 410000 series; it fits a shaft diameter of 7.000 in, an outside diameter of 8.509 in, and a housing bore of 8.500 in, with an overall width of 0.625 in, and it is Redi-Coat ready. Operating under -40°F to 225°F (-40°C to 107°C), it supports up to 3000 ft/min shaft surface speed and offers misalignment tolerance of 0.015 in at 800 rpm and 0.010 in at 4200 rpm to maintain sealing performance under typical industrial loading. This seal is designed for general-purpose industrial shaft sealing applications, with common replacements including SKF 70053, CR 416239, and National 416239.
