SKF 19803 Rotary Shaft Seal

The SKF 19803 is a rotary shaft seal built for engine service work. It suits mechanics and technicians who need a reliable lip seal for rotating shafts in automotive applications. Buyers who require a sealed bearing assembly or a non-contact labyrinth design should look elsewhere.

Critical Specification HM14 Design Code

The HM14 design code is the single detail that confirms fitment for the intended housing and shaft arrangement. This code defines the seal geometry and lip profile, so verifying it against the equipment manual is essential before purchase. An incorrect design code will result in leakage or premature wear.

Installation and Common Issues

Press the seal squarely into the bore using a suitable driver to avoid distorting the nitrile rubber lip. The single lip design demands a clean, burr-free shaft surface; any roughness or misalignment will cause early failure. Ensure the uncoated case seats fully against the shoulder for proper retention.

Questions about this item

What does the 2-inch inside diameter mean when I install this seal in my engine?

The 2-inch inside diameter matches a 2-inch shaft, so the seal fits directly on that shaft size without adapters.

How does the HM14 design code limit what this seal can handle in service?

The HM14 design is rated for a maximum pressure of 10 psi and a maximum surface speed of 999 mps.

What physical dimensions must my housing and shaft have for this seal to fit and mount correctly?

The seal needs a 2-inch shaft diameter, a 2.75-inch housing bore, and 0.234-inch overall width to seat properly.
