Expander System eliminates pivot wear by locking in place a tapered pin through the use of slotted expansion sleeves.
the life of the machine. “The standard expansion system consists of an assembly including a pin body that’s tapered at both ends, two slotted expansion sleeves, two tension washers and two fasteners,” explained company President Roger Svensson. “When you torque the fasteners, the tension washers push the expansion sleeves up the tapered part of the pin, thereby locking the system into the lug ears and eliminating the movement that causes pivot wear. Problem solved – once and for all.”
“To demonstrate our confidence in the product, we offer a 10-year, 10,000-hour warranty” Svensson founded Expander System in 1986. Soon after, the company was awarded the Nobel Prize for Innovation and Development. Expander System has been granted numerous
patents in the years since, as it continually works to improve the product. “To demonstrate our confidence in the product, we offer a 10-year, 10,000-hour warranty on the locking mechanism of Expander System,” says Svensson. “But based on years of field testing and results from end users, we fully expect it to last much longer than 10,000 hours, even in the most abrasive environments.” The Expander System is usually sold as an aftermarket part, but major machine manufacturers also use it as a factory “firstfit” OEM part for construction, mining, forestry and offshore oil and gas rig equipment. The products fit, or can be custommade to fit, every machine in the world – from the smallest to the largest, and any make, model or manufacturer.
