Description

Naval brass Sleeve bearings are preferred in marine environments as they are corrosion-resistant and suitable for salt or fresh water. The outer brass casing is durable and polished for precision fitment. Internally reinforced nitrile rubber offers excellent resistance to wear, abrasion, and chemicals, making them ideal for harsh marine conditions. The fluting allows water to lubricate and cool while flushing particles to prevent scratching or pitting.
