SKF 5522 Rotary Shaft Seal HM14

The SKF 5522 is a single-lip rotary shaft seal built to HM14 design code for grease-lubricated agricultural machinery. It fits a shaft diameter of .563 in and a bore of .875 in with an overall width of .188 in. The nitrile rubber lip handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils.

Sustained load behaviour

Under continuous operation the seal is rated for a maximum rotational speed of 660 RPM and a pressure limit of 10 psi. The single nitrile lip maintains contact with the shaft to retain grease and exclude contaminants during extended duty cycles. No spring is fitted, so sealing force relies solely on lip interference and material elasticity.

Practical interface limits

The inch-dimensioned housing requires a bore of .875 in and a shaft of .563 in with adequate surface finish for the nitrile lip to function. The 10 psi pressure ceiling and 660 RPM speed cap define the operational envelope for the specified fluids. Exceeding either limit risks lip roll-over, excessive wear or leakage.

Questions about this item

How much heat and noise does the SKF 5522 generate at its maximum 3,660 RPM?

The nitrile lip and single-spring design produce minimal frictional heat and virtually no audible noise at 3,660 RPM in grease-lubricated applications.

What shaft and housing dimensions must already be present for the 0.563 in ID and 0.875 in OD seal to seat correctly?

A shaft of 0.563 in diameter with a suitable surface finish and a housing bore of 0.875 in are required for proper press-fit installation.

Will the 0.188 in wide HM14 seal replace older seals that used different lip materials or case coatings?

Yes, the nitrile lip and uncoated case are compatible with the same shaft and bore dimensions used by many legacy agricultural and light-industrial seals.
