Original Bellows Shaft Seal

The Original "Bellows" face seal features a vibration-absorbing bellows ideal for use on sailboats, powerboats or workboats. Our AMORFLEX bellows are second to none. This product is constructed of silicon rubber and hand wrapped in three layers of fiberglass on the inside. The unit is then vulcanized, providing not only superior strength and durability, but also resistance to heat and diesel fuel.

Specially balanced for smooth rotation, the maintenance-free "Original" features 316 grade stainless steel and special carbon graphite for its sealing surfaces for shafts of 3/4" to 4" in size. For larger-sized shafts, 4-1/8" to 8", we use 316 stainless steel and an Oil Impregnated Nylon (OIN) seal surface. The OIN has superior resistance to suspended solids, such as sand and silt, and is tough, durable and won't crack or shatter. Like all Lasdrop models, a cutlass bearing is incorporated in to the product to ensure correct alignment with the shaft. The Original Bellows seal will fit stern tubes from 1-1/2" to 10-1/2" in diameter. Metric sizes also available.

• Clamp Ring assembly uses two clamps for maximum strength and proper balancing, preventing galling or damage to the shaft that can occur with setscrews.
• Seal ring is 316 stainless steel, set in a counter bore in the clamp ring assembly to ensure centering, eliminating metal-to-metal contact and risk of electrolysis.
• To insure the "O" Ring is not damaged during installation, it is clamped to the shaft after the assembly reaches it’s final location.
• AWAB hose clamps are 316 stainless steel, manufactured with indentations rather than perforations, providing twice the tensile strength and eliminating friction as in regular clamps.
