Higher Load Capacity, Longer Bearing Life As the track modules are subject to shocks when a vehicle runs over rocks and other obstacles, GGB recommended using GAR-MAX® fiber-reinforced composite plain bearings to provide good friction and wear properties under slow-speed oscillating or rotating movements, like those of the tensioning mechanism for ATI’s modular track systems. In addition to their high load capacity and extended bearing life, GAR-MAX® self-lubricating plain bearings also exhibit good resistance to shock loads and chemical attack. Another requirement of ATI Inc. was to provide the 10,000 to 12,000 operational hours required by their construction equipment customers. After testing, GAR-MAX® plain bearings were shown to provide around 25,000 hours: more than double the safety factor. All bearings in the track system are sealed and lubricated for life, reducing the customer’s need for maintenance. GGB’s GAR-MAX® plain bearings are an ideal match for the application as their self-lubricating properties provide maintenance-free operation. Related links: ATI Inc.
