Compact sealing for needle bearings with the Skf seal

Practical benefits

Compact low profile design: With a narrow 4 mm width, you easily fit this radial shaft seal into tight needle roller bearing arrangements.
Dependable retention and exclusion: The single sealing lip tightly hugs the 20 mm shaft, retaining lubricant while keeping external contaminants out.
Secure damage free installation: The rubber outside diameter with steel reinforcement seals the 28 mm housing bore securely without risking bore damage.

In a nutshell

The right choise for

With the Skf g 20X28X4 radial shaft seal, you reliably protect compact needle roller bearing arrangements against contaminants and lubricant loss. Thanks to its narrow 4 mm width, you easily install this seal where axial mounting space in gearboxes and drive systems is strictly limited. The single nbr sealing lip tightly hugs the 20 mm shaft, while the steel-reinforced rubber outside diameter ensures a secure fit in the 28 mm housing bore without causing damage during installation. This maintains optimal lubrication and extends the service life of your rotating equipment.

Product description

Radial shaft seals with low cross-sectional height are intended for bearing arrangements that incorporate needle roller bearings. These contact seals are designed without garter springs. G design seals are made of rubber, with a single lip. Seals for shaft diameters >= 8 mm are reinforced with sheet steel. The rubber outside diameter enhances the seal around the housing bore and reduces the risk of damage to the seal and housing during installation and removal.
