Miller AL4 SeriesAir CylindersBumper Seal OptionBumper Seal Piston OptionImpact dampening Bumper Seals are now optional on allMiller AL4 air cylinders from 1-1/2" to 4" bore. TheBumper Seal piston combines the features of lowfriction,round lipseals and impact-dampening bumpersto provide reduced noise and smoother end-of-strokedeceleration. At pressures greater than 80 psi, thecompressible Buna Nitrile Bumper Seal has a minimaleffect on stroke loss. When specified, Bumper Seals willbe supplied on both ends of the piston, eliminating theneed to specify head end or cap end only.Specifying the Bumper Seal piston feature on Miller AL4 cylinders provides many benefits, such as:Advantage BenefitReduced noise upon piston impactQuieter operating environmentMinimal loss of stroke (or added piston thickness)Space-efficient design for applying cylinders in tight spacesSmoother end-of-stroke deceleration when used in combination with cushions Efficient cushioning increases cylinder and machine lifeRounded sealing lip is rated for non-lube serviceLong seal life without the need for external lubrication38
