Perfect for my propeller shaft
Installed these on my boat last month. The rubber cladding provides a great seal and the brass holds up well against the shaft. No leaks so far.

Good but tight fit
Quality is excellent, but the outer diameter was slightly tight for my housing. Had to use a press to install. Once in, they work great.

Excellent wear resistance
We use these in our freshwater cooling systems. They last much longer than standard brass sleeves. The rubber layer reduces vibration noticeably.

Durable and reliable
I use these for pump repairs frequently. They are wear-resistant and the water lubrication works exactly as described. Highly recommend for marine applications.

No corrosion after 6 months
Been running in saltwater conditions for half a year. No signs of corrosion on the brass and the rubber is still flexible. Very satisfied.
Q: Are these suitable for continuous saltwater immersion?
A: Yes, they are marine-grade and designed to withstand continuous saltwater exposure without corroding.
Q: What is the hardness rating of the rubber layer?
A: The nitrile rubber cladding has a Shore A hardness of approximately 70, providing a balance of flexibility and durability.
Q: Is there a warranty included with this product?
A: Yes, these bearings come with a standard 1-year manufacturer warranty against defects in material and workmanship.
Q: Do I need adhesive to install these sleeves?
A: Typically, a press fit is sufficient. Adhesive is not required unless your housing specifications demand it for extra retention.
Q: Can these bearings be used with oil lubrication instead of water?
A: These are specifically designed for water lubrication. Using oil may degrade the rubber cladding over time. We recommend sticking to water.
