Johnson Cutless® Non-Metallic Sleeve Bearings (3” x 4”)

Shaft Size: 3". OD: 4". Length: 12". These bearings feature a dense structure of engineered reinforced thermoset plastic. The specially compounded Nitrile Rubber is securely bonded to the shell with all tolerances maintained for proper lubrication. Being non-corrosive and inherently resistant to all known chemicals, oil and grease, as well as being anti-electrolytic, the Johnson Cutless Non-Metallic Sleeve Bearings are ideally suited for installations wherever corrosion or electrolysis is a problem. PRECAUTION: When shrink fitting of the bearing is required, chilling must be achieved by gradual cooling to not more than minus 20� F (-28� 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. All other standard sizes available upon request.
