STANDARD FLANGED MARINE BEARINGS

Heavy-duty flange bearings are engineered to meet the toughest application requirements in marine and industrial applications. The flange type bearing requires only a light press fit and is locked into position by bolting thru the flange. The flange is supplied plain enabling you to machine bolt holes to individual requirements.

They operate in any water-base liquids, most chemicals and petro products. Operating temperatures range from +39º to 158ºF, +4º to 70ºC.

Normal loading capacity up to 35 psi, .0246 kg. per sq. mm. Shaft is cushioned by continuous flow of 2 gals/in.; 7.5 liters/25 mm of shaft diameter/min. through the bearing.

All materials meet U.S. Navy specifications. MIL-B-17901A CLII.

Prices on split shaft bearings and other sizes available on request.

Bolt holes drilled to your requirements. Prices furnished upon request.

Sizes thru 12” shaft diameter are in stock for immediate shipment. All other standard sizes manufactured on request.

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.
