In the world of industrial handling<\/strong> and controlled friction mechanical systems<\/strong>, the choice of bushing material is crucial to ensure durability, smoothness, and reliability over time<\/strong>.
\nToday, self-lubricating compounds<\/strong> represent one of the most efficient solutions, eliminating the need for external lubricants and minimizing the wear of associated metal components.<\/p>\n

Self-lubricating Bushings for Forklifts: the GGB Case<\/h2>\n

A major forklift<\/strong> manufacturer has designed an innovative steering system, where the steering column<\/strong> can rotate 30\u00b0, facilitating operator access to the cabin.
\nThe movement is made possible by two self-lubricating bushings<\/strong> developed by GGB<\/strong> using the LATILUB EP\u00ae22 compound<\/strong>, based on PBT and loaded with PTFE.<\/p>\n

Advantages over Traditional Reinforced Materials<\/h2>\n

Previously, bushings were made of glass fiber reinforced polymers<\/strong>, but this solution accelerated the wear of the oscillating metal column.
\nThe EP\u00ae22 self-lubricating compound<\/strong>, free of glass fibers, eliminates the abrasion problem, ensuring: <\/p>\n
