BS/UR is a lip seal with a secondary sealing lip and tight fit at the outer diameter. Wear and dry run are largely prevented by the additional lubricant retained under the seal by the secondary lip.
BS is mainly designed for the sealing of piston rods and plungers in heavy duty applications in mobile and stationary hydraulics.
