Mining excavators and shovels


The slewing bearing OEM alternative

When it's time to replace or repair a worn hydraulic excavator or shovel slewing bearing, mine operators are saving $100,000s by choosing Kaydon, an SKF Group brand, over the OEM.

New replacement for any OEM slewing bearing
Kaydon manufactures new slewing bearings to any OEM specs, applying the same engineering expertise we use to design new bearings for flight-critical aerospace and defense applications. Kaydon's slewing bearing inventory includes many excavator and shovel makes and models. If we don't have your model on hand, we can design and manufacture a new bearing to order.

You can count on your new Kaydon replacement bearing to meet or exceed the original OEM specs; perform as well as or better than (and as long as or longer than) the original; and come with a prorated two-year warranty*. Kaydon is the OEM alternative that can save large mine operators hundreds of thousands of dollars.

Remanufactured slewing bearing for any OEM
Through Kaydon's bearing remanufacturing process, worn bearing cores are thoroughly inspected and repaired to meet or exceed original OEM specs, with as-new or better performance and a full one-year warranty. Our slewing bearing inventory includes some remanufactured cores as well as new replacement bearings. If we don't have your model in inventory, we can locate a core or remanufacture your worn bearing.

Mine operators have saved up to $250,000 and found that their Kaydon remanufactured bearing lasts as long or longer than the original. Others order a new replacement and have us remanufacture their worn bearing to use as a spare. Find out how much major mine operators have saved in our surface mining newsletter.

Have a worn bearing you'd rather sell? Ask us about our bearing purchase program.

* Full warranty for 15 months after date of delivery, then declining cost of replacement of ten percent (10%) each month to twenty-four (24) months after date of delivery.
