Mining Bearings


Mining is arguably one of the most demanding operating environments of any industry and will extract the most punishing wear on equipment and their components. Subject to dirty, humid, cold, abrasive and wet conditions, greased bronze bushings traditionally used in mining equipment require regular maintenance. This is not the case with Thordon Bearings. As an ideal replacement for greased bronze bushings, Thordon grease free bushings can be found in countless mining equipment applications; crushers and feeders, skip pivots, centrifuges, chaseblocks, and truck stabilizers. Thordon bearings are a proven solution offering a comprehensive lineup of polymer bearings that continually outperform traditional greased bushings, by significantly reducing associated operating and labour costs. By maintaining stability through heavy shocks with littler wear, Thordon bearings significantly decrease downtime by reducing the frequency of maintaining bushings.

Use the Material Selection Guides below to determine which Thordon bearing grade is best for your application.

  • Performs well in abrasive environments
  • Long wear life, low maintenance, and no need to grease
  • Quick and easy onsite installation and conversion capability
  • Able  to withstand high impact and shock loads

ThorPlas-Blue

    Thordon Materials Keep Comeau Marine Railway Ltd. Operational Under Extreme Conditions

    Apr 13, 2021
    Thordon’s heavy-duty elastomeric bearing materials have been keeping the Comeau Marine Railway operational under locally concentrated loads and in some of the harshest, abrasive waterways for more than forty years. Comeau Marine’s 600t-capacity railway, one of Nova Scotia’s oldest patent slips, operates year-round to maintain and service much of the inshore fishing fleet as well as the parent company Comeau’s Sea Foods Ltd.’s fishing fleet.

    Omissions in Proposed VIDA has Serious Environmental Implications, States Thordon Bearings

    Dec 21, 2020
    Thordon Bearings has added to the growing concern over proposed changes to Vessel Incidental Discharge National Standards of Performance (VIDA) requirements, citing far reaching environmental consequences if clauses in the existing document are removed. In a statement submitted to the United States Environmental Protection Agency on November 20th 2020, the Canada-based bearings and seals pioneer “strongly questions the removal of some text” in the proposed amendments, stating that such omissions will mean existing zero pollution solutions will be overlooked.
