Solar protection for plain bearings: New igus material with enhanced UV resistance

Solar systems as well as other outdoor applications have to function for years often under extreme environmental conditions. This calls for machine components that offer a long service life and prolonged holding times. Plain bearings fulfil this service. For such special applications, igus now has an optimised, advanced development of its wear-resistant and durable standard material and has the long-lasting high-performance plastic, iglidur J, in its product range. This is the high-performance plastic iglidur J UV. The advanced development of this product is iglidur J UV. The new UV-stabilised material is especially suitable for continuous direct sunlight. The new material distinguishes itself with very good UV resistance and benefits from the low coefficients of friction and wear as well as the moisture resistance.

Like all igus plain bearings, the iglidur J UV plain bearings too, by virtue of their incorporated solid lubricants, are lubrication-free and thus maintenance-free as well as insensitive to dust and dirt. In addition, the long-term mechanical properties of iglidur J UV have been further enhanced. This provides the customer with the ideal material for extremely smooth-running, lubrication-free and long-lasting solar systems. iglidur J UV defies the Sun, wind and rain

Due to its corrosion-free properties and good resistance to media, moisture and other environmental influences are no obstacle to the use of iglidur J UV. The tribological properties such as friction and wear of the UV material are comparable to those of the standard material iglidur J. Its low coefficients of friction in dry operation and the extremely low stick-slip tendency are very important for very low speeds, as are common in tracking systems in the solar industry. High speeds of over 1 metre per second are also possible. In both cases, the static friction is very low, whereby, the stick-slip tendency is avoided. Bearings made of iglidur J UV are available upon request in all previous standard dimensions of iglidur J as well as in individually designed special geometries.
