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 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.

CIP uses a unique three-digit material coding system based on textile, lubricant, and resin combination.
Each CIP material is identified by a three-digit code — the first digit identifies the textile (cotton, glass, carbon, aramid), the second the solid lubricant (PTFE, graphite, MoS₂), and the third the thermoset resin system used.
This coding allows engineers to precisely specify material properties — load capacity, friction coefficient, temperature resistance, and chemical compatibility — for any application.
Cotton, woven glass, carbon fibre, and aramid textiles provide exceptional compressive strength and dimensional stability.
PTFE, graphite, and MoS₂ solid lubricants are impregnated throughout — eliminating external lubrication even underwater.
Phenolic and epoxy thermoset resin systems bond the composite for high-temperature and chemical resistance.
CIP composite bearings for lock gate and navigation structure pivots operating in submerged conditions without lubrication access.
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 — minimal friction, maximum service life in water.
Water-lubricated CIP stern tube bearings replace oil-lubricated systems, eliminating oil contamination risk in sensitive marine environments.
CIP composite rudder pintle and gudgeon bearings for boats, ships, and naval vessels — corrosion-resistant and maintenance-free.
Custom flanged, straight, and split bearings for a wide range of industrial machinery.
Self-aligning CIP spherical bearings for applications with misalignment or angular displacement.
