Motion plastics specialist igus introduces igubal spherical balls that can be inserted into existing metallic pillow block and flange bearing housings within a few seconds. These bearings, which are often used in construction machines and conveyor systems, are exposed to harsh environments requiring regular lubrication and maintenance. The igubal spherical balls are injection moulded in the high-performance plastic iglidur J, which is self-lubricating. The retrofitted bearings therefore are maintenance-free. Another advantage is that due to the absence of lubricant, dirt and impurities can no longer adhere to the bearings. Thus, there is no long downtime of the machines and plant for maintenance.

The long service life of the igubal spherical balls has already been proven in a biomass chipper. The original metal bearings on the conveyor belt of the machine had to be lubricated each month. When the flange bearings were retrofitted with igubal spherical balls, the bearings remained wear-free for more than a year, without the need for lubrication and maintenance.

The spherical balls made of iglidur J are not only cost-effective, but also have a very low coefficient of friction. As the material absorbs only little moisture, the spherical balls are also suitable for outdoor use. In addition, the high-performance plastic is also chemical-resistant and therefore the spherical balls can be retrofitted in bearings used in chemically demanding applications, such as agricultural equipment.

The igubal spherical balls are currently available in six dimensions for housing number 204-210. On request, igus also manufactures spherical balls made of other iglidur materials. As an alternative to injection moulding, spherical balls are also available machined from iglidur bar stock.

Igus

Igus is the largest producer of reinforced plastic energy chains and injection-moulded polymer bearings. The range of polymer bearings includes Iglidur plain, Igubal spherical and Drylin linear bearings. They offer an excellent price-to-life relationship and are developed under the toughest conditions. They are oil, maintenance and lubrication free, low wear, resistant to dirt and dust, corrosion free and simple to fit. Igus also has the data to precisely predict the lifetime of these bearings within a specific application.

Energy chains are the umbilical cord of modern machines. They minimise downtime and protect, support and extend the service life of cables and hoses. The broad range incorporates more than 30,000 innovative, low-cost products. From the smallest ‘micro’ chain to the largest chain in the world, the E4.350, Igus energy chains are capable of long and short travel distances at high speeds in all axes.

Igus also has its own cable series, Chainflex, specially designed with energy chains in mind. They are highly flexible cables, offering a long service life and very small bending radii. A wide range is available, from small signal cables to large power cables, high-speed data cables and glass fibre-optic cables.

The company’s energy chains and Chainlflex cables can be delivered as a fully harnessed and pre-assembled Readychain system, cutting purchasing, warehousing and installation costs.
