Top 100: SystemOne Aims to Cut Track Costs

September 28, 2010

Caterpillar SystemOneAt the heart of Caterpillar 's SystemOne undercarriage, available for certain of its crawler dozers and loaders, is a uniquely designed and manufactured pin-and-bushing cartridge, which is sealed and lubricated for life, eliminates the need for turning pins and bushings, and allows the bushing to turn while under sprocket load. The cartridge, assembled in a clean room, is laser-welded and has lifetime internal seals. Remaining undercarriage components are essentially designed to last as long as the cartridge. The SystemOne undercarriage is estimated to cost 25 to 30 percent more than a conventional system, but projections of extended life range from 50 to 70 percent.
