SKF helps coal mine double conveyor bearing life and cut operating costs
The challenge
Along with soaring maintenance costs, the mine faced excessive lubrication and disposal expenses. Looking to cut operating costs and extend bearing replacement intervals to match other conveyor maintenance activities, the mine looked to SKF.
The SKF solution
SKF suggested replacing the open bearings with sealed spherical roller bearings. Mine management agreed, and SKF installed sealed spherical roller bearings, filled all of the housings with appropriate grease, and added PosiTrac Plus labyrinth seals.The results
Average bearing service life more than doubled from two years to more than four years, ultimately resulting in substantial savings on grease purchases and disposal costs, as well as less downtime and higher productivity.The life cycle extension also enabled the mine to reach its goal of matching bearing replacements with other maintenance activities, freeing up its maintenance team for other tasks.
