BENEFITS
CIP Composites are commonly used to replace more traditional bronze, babbitt, nylon and wood bearing materials. Ideally suited for high load, slow speed applications, CIP Composites are designed to operate without external lubrication, and offer smooth, quiet performance. CIP Composites offers higher load capacity and better dimensional stability than many other nonmetallic materials. When high strength, low friction and wear are important, CIP is the clear choice.

Benefit definitions
The following is a list of common benefits to using CIP Composites, along with brief definitions. This list is in alphabetical order, not in order of most importance. Throughout the website we refer to benefits that best fit your industry, however, these benefits are true of all our materials (unless otherwise stated).
Self-Lubricating
Eliminates noisy stick-slip problems, extends operating life and reduces wear making for better operating efficiency. Low coefficients of friction can be achieved while operating dry or in wet environments. In low speed or oscillating operation CIP can offer bearing solutions with lower friction and wear rates than greased bronze alternatives. Static coefficient of friction is generally very similar to dynamic, even after prolonged periods of rest, where other materials may develop high break-away torque requirements.
Solid lubricants are dispersed evenly throughout the material, eliminating the need for external lubrication. Offering a variety of advanced lubricants, additives and material combinations CIP can provide a product solution for a wide scope of application demands.
CIP Composites are lubricated completely throughout the bearing and have no fiberglass or metallic shell. The ability to make a material that has no abrasive fillers or reinforcements allows CIP to provide a product that will not damage the shaft material, and risk equipment failure due to abrasive contact surfaces.
CIP uses high strength synthetic fibers, advanced resin systems with evenly dispersed solid lubricants and additives to create a family of materials that are highly resistive to wear and abrasion. CIP provides solutions for challenging operating conditions and environments. Slow speed and oscillatory motion can result in high wear rates with greased bearings, but are ideal for CIP Composites.
CIP materials do not contain toxic or harmful materials. CIP is self lubricating, therefore eliminates the need to introduce external lubricants such as greases which can be carried away by water or heat.
CIP materials do not contain abrasive fillers such as calcium carbonate.
CIP Composites are capable of running in fresh or salt water, many chemicals, or dry sometimes dirty environments making them an extremely versatile and durable material choice.
dimensionally stable
CIP offers materials that are stable in temperatures up to 400° F (204° C).
Being a textile reinforced thermoset resin composite, CIP is able to offer more controlled sizing and dimensional stability than other common plastics. CIP Composites also retain their strength longer at elevated temperatures, and offer materials that are capable of operating at temperatures as high as 400°F (200°C).
CIP Composites are chemically resistant to most chemicals, unlike bronze and other materials that can corrode. For excellent chemical resistance, use our high temp resin material.
<0.15% water swell on all of our products, with the exception of CIP Hydro which is rated at <0.1% water swell. This dimensional stability allows the designer to specify sizes and tolerances appropriate for the application, and have assurance that the machined material will maintain these dimensions once installed and put into operation below the water line.
CIP Composite bearings can be designed for freeze-fit, press-fit, mechanically fasten, or bonding installation.
Tubes and sheets can be easily machined onsite using conventional tooling and methods. Customers can use the same methodology as they would with aluminum or bronze. CIP is non-toxic, but the use of a dust mask and/or work area vacuum dust extraction is suggested. Carbide or diamond-tipped tools are suggested for best results.
CIP offers materials that are excellent electrical insulators providing volume resistivity of 4.2 x 10^15 ohm-cm, and dielectric strengths up to 240 volts/mil. They do not conduct heat or electrical current like metallic materials. In many cases this benefit is used to provide not only a bearing surface, but also to prevent galvanic corrosion between dissimilar metals.
CIP Composites do not swell or lose mechanical properties when immersed in fresh or salt water. Many common plastics can swell and change shape considerably, which requires careful planning, handling, and installation of the bearings. CIP avoids all these pitfalls by retaining its machined shape and tolerances even when immersed.
high compressive strength
Due to the thermoset resin construction of CIP Composites, they exhibit very high strength to weight ratio, and are highly resistant to chemical corrosion and oxidation.
Stable where side loading is anticipated, and where slight misalignment is present without damage or fracture. CIP materials offer a unique ability to provide high load capacity with enough compliance to distribute stresses when there is an edge or shock loading condition. The use of high quality thermoset resins with strong synthetic textile reinforcement results in a material with high impact and energy absorbing properties.
Ideal for high load, slow speed applications.
CIP materials are made by reinforcing resin with high strength textile giving our finished materials a compressive strength of up to 50,000 PSI, and tensile strengths up to 12,000 PSI. In addition to exhibiting high ultimate strengths, CIP materials are resilient and durable in shock and misaligned loading conditions. Their ability to absorb vibrations and load fluctuation while retaining their shape and mechanical strength set them apart from many alternative materials in the marketplace. This mechanical strength also applies to a wide range of temperatures, providing application acceptance in environments found all over the world. Commonly used to replace bronze components, CIP materials have the mechanical strength required to provide design assurance they can take the pressure and succeed.
In large bearing and component sizes, the weight savings of going from a bronze or other metallic solution to CIP Composites is substantial. Greatly reducing the material handling issues and installation challenges customers may have experienced with typical greased metallic bearing solutions.
CIP Composites are ideal for replacing traditional bronze and plugged bronze bearings. Metallic bearings require a consistent film of external lubrication for operation. CIP Composites can reduce or eliminate external lubrication systems with its self lubricating properties. Graphite plugged bronze bushings rely on full rotational movement to create an even lubrication layer. In slow oscillating applications, the lubrication layer may be uneven or non-existent and high friction or stick-slip can become a concern. CIP’s even distribution of lubrication additives allow for low dynamic and static coefficients of friction, eliminating stick-slip and noise.
