Composite Marine Pump Shaft Bearings

Composite bearings, both cylindrical and flat, are manufactured from synthetic polyester resins combined with fabric that ads strength and durability to the finished product.   Combined with the resin is a lubricant that can be changed depending on the application.  For marine and hydro bearings PTFE and molybdenum disulfide are commonly used.  For industrial bearings graphite is commonly used.  Changes can be made depending on the project requirements.

The material displays exceptional dimensional stability when immersed in water, acids and chemical solutions. 

These bearings have excellent low friction qualities in wet conditions and provide very low conductivity and will not promote corrosion in unprotected steel housings and shafts.

The manufacturing process for cylindrical bearings is by wrapping the materials on a mandrel to make the rough bearing followed by a machining process to finish the bearing.  This means that bearings can be made of any inside diameter or outside diameter as needed.  Sheet of material are also available.

Actual production for a bearing is about 1 day plus machining time so quick delivery is possible if there are time constraints.

If there is an emergency, barring other projects, a 2 or 3 days delivery is not out of the question.
