SKF 17240 Rotary Shaft Seal
The SKF 17240 is a rotary shaft seal designed for grease-lubricated agricultural machinery. It features an HM14 design code with a single nitrile rubber lip suitable for animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils. The uncoated case measures 1.75 in inside diameter, 2.25 in outside diameter and .188 in overall width. Maximum rotational speed is 3,162 RPM at 10 psi pressure.
Verify shaft dimensions and fluid compatibility
Confirm the shaft outer diameter matches 1.75 in and the housing bore matches 2.25 in before ordering. The seal width of .188 in must fit the available gland depth in your equipment. Ensure the operating fluid is listed among the compatible media such as greases, mineral oils or diesel. Check that shaft speed does not exceed 3,162 RPM and pressure stays below 10 psi for reliable sealing performance.
Single-lip NBR design simplifies installation
The single nitrile rubber lip with no spring reduces assembly complexity compared to multi-lip or spring-loaded alternatives. Uncoated case material allows direct metal-to-metal fit in standard bores without additional surface preparation. HM14 design code indicates a specific profile optimised for the stated fluid range and speed limit. No extra tools or lubricants beyond the application grease are required for fitting.
