Ultracomp Composite Bearings are designed for extreme loads where impact and vibration may occur. Because of it’s very high impact strength it can take extreme loads as well as shock loads. Ultracomp requires no lubrication which eliminates maintenance, is much kinder to the environment and reduces overall costs of ownership.  Ultracomp absorbs virtually no moisture, takes static loads up to 55,000 psi and handles dirty, gritty environments. Ultracomp is also an excellent underwater bearing for applications as diverse as bowthrusters, rudder bearings, roller bearings, dockside equipment exposed to salt air and water. Also an excellent bearing material for construction, material handling and ag equipment.

Rulon bearing materials, and other filled PTFE materials like Fluorosint and Ultraflon, have a unique reaction where coefficient of friction is concerned. Unlike most materials which theorize that higher loads and speeds mean higher friction, filled PTFE products are just the opposite. WIth these materials, the higher the load – the lower the friction. Same goes for speed as a general rule. Design your PTFE bearings with the thought in mind that surface contact area can be reduced dramatically to optimize friction properties. Remember, more is not necessarily better when it comes to PTFE based bearing materials.
