BRASS MARINE BEARINGS
SELECTION – Sleeve and Flanged Bearings
Normal design practice is to select a bearing with a length equal to 4 times the shaft diameter. It may be acceptable to deviate from this rule when application load requirements permit the use of shorter bearing lengths.
The projected bearing area is the product of bearing I.D. (Shaft Diameter) x Bearing Length. Therefore the loading capability is determined by multiplying the Bearing Area x 35 psi.
Caution: If the bearing is to be shrink fitted, care is required to prevent damage to the bearing. Cool the bearing gradually. Do not cool the bearing below -20ºF (-28ºC). Dry ice or other super cool materials SHOULD NOT BE USED. Pounding the bearing in a chilled state can cause damage to the bond between the rubber and the shell material.
• Replacement clearances per Dept. Navy Ship System Command Tech Manual NAVSHIP 0901-0002. Standard practice for bore measurement is with plug gauges.
