Dependable protection with Skf seals

Practical benefits

Low cross sectional height: You can easily fit this seal into compact needle roller bearing arrangements where radial space is extremely limited.
Effective lubricant retention performance: The contact lip retains essential lubricants inside the bearing while reliably keeping external dust and contaminants out.
Reduced risk of damage: The rubber outside diameter improves housing bore sealing and helps you prevent damage during installation and removal.

In a nutshell

The right choise for

Protect your compact needle roller bearing arrangements reliably against dirt, dust, and moisture with the Skf g 30X40X4 radial shaft seal. Featuring a low cross-sectional height with dimensions of 30 mm x 40 mm x 4 mm, this seal fits easily into tight assemblies where standard oil seals are too wide. The nbr contact lip retains lubricating oil and grease inside the bearing, reducing wear and extending the service life of shafts and machinery. Reinforced with sheet steel, its rubber outside diameter provides optimal sealing in the housing bore while preventing damage during fitting, ensuring dependable operation in temperatures from -30 °C to 110 °C.
