Reduce maintenance in high contamination joints

miningEach project has its own set of unique challenges, sources of delay, and scheduling constraints. Polygon Company can be a source of certainty when it comes to equipment reliability by eliminating the need for maintenance. Operators can focus on productivity instead of trying to remember if they greased that hard to reach area or checked the oil reservoir. Polygon composite bearings keep assets producing while eliminating some of the labor cost associated with frequent preventative maintenance.

Maintenance Free, Never Needs Greasing

PolyLube composite bearings are used in many pieces of mining equipment. Many of these joints are unsealed and all of them run dry. With the PolyLube line of products, customers can worry about project timeline, equipment logistics, and project bids rather than number of hours since the last round of grease, who can I get to do the greasing, and is my worker reliable enough to find an hit the hard to reach joints.
