Polygon Company has collaborated with partner and distributor Kuhne Industrie to supply composite bearings to a major feeding technology company for use in a demanding mixer cart application.

The feeding technology company client in this case delivers premium feeding technology, including feed mixers and automatic feeding systems, to livestock farmers globally. The company’s feeding technology helps modern livestock farmers manage their farms more efficiently, and they consistently work to design new solutions and develop existing technologies to better suit farmers’ needs.

This company tested several other bearing types in their feeding technology applications, but all of the tested materials led to excessive wear and premature failure, loud noise, or couldn’t be properly sized to fit the application. In particular, after experiencing difficulty finding bearings that could stand up to the demands of their mixer cart’s walking tandem axle design over time, this company turned to Kuhne Industrie to find a better solution. Kuhne recognized that their longtime partner and supplier Polygon would be able to supply custom composite bearings to solve the customer challenge and extend the lifespan of the walking tandem axles.

Polygon worked together closely with Kuhne Industrie and the customer to select a composite material that would be suitable for withstanding the aggressive wear from the mixer cart’s axles, given the application’s high load and high oscillation. The result of this collaboration was a custom-designed composite bearing that eliminates prior issues of excessive noise and uneven wear. As a result, Polygon’s bearings help to reduce maintenance needs and extend the lifespan of the mixer cart product. Polygon’s bearings were immediately retrofitted onto existing equipment in the field and will be incorporated into the mixer cart’s manufacturing going forward.

The high-performance custom-engineered and standard composite plain bearings on display are ideal for challenging construction equipment applications, including wheel loaders, excavators, backhoes, and compact track loaders, as well as other applications requiring pivot joints with a long life expectancy. Featuring high load-bearing capacity, low frictional values, and corrosion resistance, the Polygon composite bearings are self-lubricated, requiring no greasing. This reduces maintenance labor costs and increases the interval before maintenance is required on rental equipment. It can also lower the number of greasing locations, ultimately resulting in fewer equipment warranty claims.

Also on display will be PolySlide composite tubing for pneumatic and low-pressure hydraulic applications, including fifth wheel actuation, gate valve actuators, water treatment flow control mechanisms, and tie rod cylinders. PolySlide tubing replaces metallic material in a variety of cylinder applications. Supplied as a cylinder tube ready for customer assembly, or as fully engineered cylinder assemblies for equipment manufacturer applications, the tubing is made of continuous filament-wound glass fiber and polymer resins. The fiberglass filament and resin materials combine together to form a high strength component that exhibits dimensional stability, is non-corroding, impingement resistant and is non-conductive. PolySlide is the solution for service in harsh environments. The cylinder tubing performs in high and low temperatures, grease, grit, salt, chemicals and other extreme conditions.

Polygon composite bearings are also an excellent choice for high-cycle agricultural equipment, including implements, foraging and harvesting equipment, applicators, carts, and spreaders. The greaseless bearings also help maintain cleanliness inside warehouses, avoiding any potential contamination of the work area by pallet lifting equipment.

Polygon composite bearings are made of continuous filament-wound glass fibres, polymer resins, and polytetrafluoroethylene (PTFE) fabric liners. The fibreglass filament and epoxy resin combine together to form a high strength backing. This precise filament-wound fibreglass structure allows for thin-walled, lightweight bearings. The bearings are typically retained through outside diameter (OD) interference fit.  Experts tailor material to fit customer requirements and provide engineering consultation and expertise.

The field retrofittable Polygon bearings can replace existing metallic bushings without changing mating parts, so they can be used to improve wear material without requiring complete equipment redesign. Availability of small-batch/short-run drop-in replacements means customers can increase bushing OD and length without a large tooling investment.

Working closely to help determine the right product for the application, Polygon engineers specify the proper bearing dimensions for the given available space, interference fit, clearance fit, and any limiting factors associated with retention, bearing OD/ID, axial stress, and hoop stress.
