The commonly harsh operating environments for heavy-duty conveyors often result in premature bearing failures, with costly downtime and repairs as a consequence. The traditional solutions to this problem are expensive sealing or a greasing procedure with a negative financial and environmental impact. Now, an SKF solution provides a convenient and cost saving solution to this problem. The conveyor unit sealed spherical roller bearing dramatically reduces the need for lubrication, extends mean time between failures and may improve the return on investment.
