Columbia Industrial Products (CIP) was founded in 1998 by Stephen Phillips in Eugene, Oregon, USA. CIP is a manufacturer and global supplier of custom composite bearing materials focused on high-strength, low-friction textile reinforced composites.
CIP bearings are laminated polymer materials made by impregnating textiles with thermoset resins and solid lubricants. The resulting material is self-lubricating — requiring no external grease or oil — and performs exceptionally in wet and submerged conditions.
Nvirotech is CIP's authorised distributor in India, providing local engineering support, custom fabrication, and fast delivery to Indian customers.

CIP uses a unique three-digit material coding system based on the combination of textile, lubricant, and resin used in each grade.
Each CIP material is identified by a three-digit code — the first digit identifies the textile (e.g., cotton, glass, carbon, aramid), the second the solid lubricant (e.g., PTFE, graphite, MoS₂), and the third the thermoset resin system used.
This coding system allows engineers to precisely specify material properties — including load capacity, friction coefficient, temperature resistance, and chemical compatibility — for any given application.
Cotton, woven glass, carbon fibre, and aramid textiles provide the structural backbone, giving CIP composites exceptional compressive strength and dimensional stability.
PTFE, graphite, and molybdenum disulphide (MoS₂) solid lubricants are impregnated throughout, eliminating the need for any external lubrication — even underwater.
Phenolic and epoxy thermoset resin systems bond the composite for high-temperature resistance, chemical resistance, and long service life in demanding environments.
CIP composite bearings are ideal for lock gate and navigation structure pivots that operate in submerged conditions without access for lubrication.
Water-lubricated CIP shaft bearings for deep-well vertical turbine pumps, replacing traditional grease-lubricated bronze bearings.
CIP trunnion and gate bearings for hydroelectric turbine wicket gates, designed for minimal friction and maximum service life in water.
Water-lubricated CIP stern tube bearings replace traditional oil-lubricated systems, eliminating oil contamination risk in sensitive marine environments.
