Shaft Seal 1.5 x 2.125 in
The SKF 14875 is a rotary shaft seal designed to retain lubricants and exclude contaminants in automotive engine assemblies. It suits mechanics and engine builders who need a reliable lip seal for a 1.5 inch shaft diameter. This component is not for buyers who require a double-lip design or a seal rated for pressures above 10 psi.
Sustained Load Performance
The seal operates up to a maximum rotational speed of 3,360 RPM and a surface speed of 6.74 mps using a single nitrile rubber lip and carbon steel spring. The acrylic-coated case resists animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil, and mineral oils. Continuous operation beyond the stated speed or pressure limits will accelerate lip wear and leakage.
Installation Notes
Press the seal into the housing bore of 2.125 inches outside diameter using a flat driver that contacts the outer case only; avoid hammering the lip. The 0.313 inch overall width must match the housing depth to prevent cocking. Damage usually occurs when the lip is folded back during shaft insertion or when the spring is dislodged by an unchamfered shaft edge.

Questions about this item
How much heat does the NBR lip generate when the seal runs continuously at 3,360 RPM?
The nitrile rubber lip is rated for a maximum surface speed of 6.74 mps and a pressure limit of 10 psi, so heat build-up stays within design limits at the rated speed.
What shaft diameter and housing bore must I already have for the 1.5 in by 2.125 in seal to fit?
The seal requires a 1.5 in shaft diameter and a 2.125 in housing bore to match its inside and outside dimensions.
Will the acrylic-coated case and carbon-steel spring hold up against the mineral oil in my older engine?
Yes, the seal is listed for mineral oils, gasoline, diesel, greases and other fluids, and the acrylic coating plus carbon-steel spring are compatible with those media.
