Johnson Cutless® Naval Brass Sleeve Bearings adapt equally well to strut and stern
tube mounts, and are often used effectively as rudder-stock and pintle bushings.
Bearing diameters are precision fitted to the designated shaft size with the correct
clearance for efficient water lubrication. External brass shells are machined and
polished to provide easy fitting.
Specially formulated oil and chemical resistant nitrile rubber is securely bonded to the
shell. Units with thin shells are available for the struts of small craft. Sleeve bearings are
usually installed by light press-fitting and locked in place with cone-pointed set screws.
PRECAUTION: When shrink fitting of the bearing is required, chilling must be
achieved by gradual cooling to not more than minus 20Ú F( -28Ú C) using freezer or
regular ice ( DO NOT DRY ICE) . NOTE: Pounding or shocking the bearing while in
the chilled state could cause the rubber to separate from the shell.
Approved Bearings: Johnson Cutless® Naval Brass Sleeve Bearings meet military
specification MIL-B-17901 ( Ships) Class II Full-Molded type and have full type
approval from The American Bureau of Shipping.
