CIP Composites are laminated polymer materials made by impregnating textiles with thermoset resins. Solid lubricants are added to the resin to provide evenly dispersed lubrication throughout the material, providing smooth operation.
CIP custom composite wear rings are a superior alternative to commonly used cotton phenolic and glass filled nylon materials. They allow smooth operation and high side loads while protecting the sealing elements and preventing metal to metal contact in hydraulic cylinders. CIP wear rings are preferred where high performance, large diameters and/or high temperatures are required.
CIP Composite wear rings provide manufacturers and servicers alike with solutions to reduce overall maintenance and increase wear life. CIP offers short lead times, reducing the costs associated with equipment downtime and repairs. CIP Composites are manufactured in the United States using only the highest quality materials.
Vesconite’s origins lie in the gold mining industry, a notoriously harsh working environment. The product was developed as a maintenance-free alternative to bronze bushings traditionally used in mining equipment. Unlike bronze, Vesconite eliminates three key issues: The need for regular lubrication; the effects of dirt and grit on costly components; the damage caused by water to traditional bushing materials. Vesconite offers up to 10 times the lifespan of traditional bushes in these harsh conditions, and saves hours of downtime caused by machines requiring frequent lubrication.
Vesconite Bushings on a Vertical Borer Stabilizer Rod
South Africa – A earth-boring company was looking for a durable material to create stabilizers for its borer machines. The machine bores between levels in mines and is capable of boring chutes up to 120m. The drill steel is subject to high levels of grit and rock. The Vesconite stabilizers help align the drill steel, thereby avoiding whip in the drill. Despite the dirty conditions, the new stabilizers required no lubrication between recommended overhaul schedules, and general maintenance and downtime were substantially reduced.
Equipment manufacturers, suppliers, and drill service providers have become highly competitive to secure remaining contracts in order to stay operational during this recent downturn in the industry. Looking for new strategies to succeed in this current market, companies are investigating alternative products and designs to maximize flexibility and efficiencies. Whether in the exploring, drilling, or production of oil, equipment manufacturers are looking for products that provide high levels of performance that will set themselves apart from the competition.

Whether you’re a farmer, repairer or manufacturer of harvesters, planters, sprayers, harrows, etc, Vesconite and Vesconite Hilube should be considered as bushing and wear material substitutes.
I can’t understand why more farmers don’t use Vesconite. -Old Farmer
This comment was made by an old farmer who had driven 185 miles (300km) to buy Vesconite bushings from our Johannesburg sales office. We can’t help but agree with this sentiment – that any farmer who hasn’t tried Vesconite for bushes, and other sliding wearing parts is unwittingly creating unnecessary work and expense for themself.
CIP Composites offer design engineers an attractive, cost effective alternative to the traditional materials used for bushings, bearings, wear pads, and thrust washers, such as bronze or nylon. CIP Composites are only 1/6 the weight of steel, easily machined, have good dimensional stability and do not contain harmful or toxic materials.
CIP offers material selections that provide high load capacity, and dimensional stability in high temp applications, up to 400°F (200°C). Materials such as CIP333 and CIP353 are manufactured with meta-aramid textile for reinforcement, a high-quality vinyl ester resin, and solid lubricants evenly dispersed throughout the entire material.
Industrial applications can be found in many industries and range from hydraulic cylinders to heavy duty equipment. Many industrial applications are in harsh environments including dirt and mud, chemicals, a range of temperatures, and hard to reach locations, making maintenance a challenge. Equipment down time for maintenance and repairs can be detrimental to the industry.
CIP Composites offers solutions for rigorous industrial applications by extending wear life while reducing or eliminating external lubricants and undesired maintenance. As a general guide, CIP Composite bushing materials can replace your current bronzeor nylon based wear and bearing materials. Sold in tubes or sheets for easy machining onsite, or custom manufactured with short lead times.
Hydraulic & Pneumatic
Hydraulic cylinders are the ideal choice for a host of mobile and industrial applications where power and reliability, along with low operating costs are required. Hydraulic (and even pneumatic and electrical actuator) cylinders are handling more demanding applications than in previous years, such as the use of smaller cylinders which force higher and higher operating pressures. Manufacturers and servicers alike depend on quality components to ensure that their finished product meet or exceeds the customer requirements including long service life, affordability, and availability.
The dirt, abrasion and loads associated with earthmoving equipment create notoriously harsh operating conditions for moving parts. Despite these conditions – more often than not combining dirt and water – Vesconite performs well, and is the ideal material for bushings operating under slow speeds or oscillating movements under high load. With its lubrication-free qualities, Vesconite can save machine operators considerable lubrication downtime, not to mention reduced wear on costly counter moving parts.
UK Dump Truck Manufacturer Continues to Fit Vesconite Bushings
United Kingdom – An original equipment dump truck manufacturer first tested the company’s Vesconite Hilube material in its articulation bushes in 2014, and established that they performed well in harsh operating conditions including large-scale construction projects, quarries and mine sites. The 355.95mm-outside-diameter Vesconite Hilube bushings were found to be cost-effective with prolonged durability in the long-run. The dump-truck manufacturer continues to order Vesconite bearings for its 38 ton dump trucks, which have a heaped capacity of 23.3m3 and an engine power of 331kW.
Vesconite has over several decades been successfully used in a number of railway applications. The material’s self-lubricating properties make it well suited to railway components that are prone to metal on metal wear and require regular greasing. Not only will a switch to Vesconite bushings avoid long periods of downtime, the noise and squeal issues commonly associated with rolling stock, is significantly reduced. With a resultant reduction in rolling resistance, considerable power savings have been noted with the use of Vesconite components.
Vesconite Hilube on Tram Drive Bushings
Australia – An Australian tram operator continues to order approximately 100 Vesconite Hilube motor axle bushings a year, following its successful introduction to the product in 2006. The motor axle bushings, which require no lubrication and are wear resistant, have completely replaced the standard metal main drive H-class-tram bushings, which had been in use prior to the introduction of the polymer product.
The sluice gate at Faraday Dam in Oregon operates fully submerged with approximately 40′ of head at the middle of the gate. The estimated operation pressure on each of the bushings is around 4,000psi (4ksi). The gate is used for water level control, therefore continuously makes small adjustments to its elevation.
The gate was removed in September 2014 to perform inspection of gate wheel assembly and bearings. It was determined that several of the wheels had either stopped working or fallen off due to corrosion and lack of lubrication. The remaining bearings were found to have excessive clearance due to wear. New stainless steel sleeves were fabricated by Portland Manufacturing and welded onto the gate wheel stub shafts. New composite greaseless bushings supplied by CIP were installed to replace the failed bearings.
Transportation / Automotive bushings require regular maintenance and greasing, and are prone to wear especially in wet or dirty conditions. Self-lubricating Vesconite and Vesconite Hilube eliminate the need for continual greasing and at the same time increases bushing life. Vesconite and Vesconite Hilube are tough and durable and perform well under the mechanical stress that occurs on vehicle suspension systems.
Rail container trailers fitted with Vesconite
South Africa – Vesconite flanged pivot bushings have been successfully installed and used on container trailers at the national rail utility. The Vesconite bushes, with a flange of 205 mm diameter and a bore of 165 mm, were fitted to the walking beam center pivot bearing that equalizes component parts of the rear axle bogies. This heavy duty application required a material which had high load carrying capacity, low friction, high wear resistance and good dimensional stability. Vesconite, with all these characteristics, was used on the trailers that are used to transport 12-m-long general purpose containers.
