Aggregate Plant Cuts Downtime and Saves US$50K with Sealmaster RPB Bearings
An aggregate producer was facing costly downtime and frequent maintenance due to bearing failures occurring every three weeks. These failures were caused by the extreme conditions of a ‘wet fines’ transfer conveyor, where abrasive slurry quickly compromised standard bearing seals. To address the issue, the operation upgraded to the Sealmaster RPB – a bearing designed specifically for tough, high-contamination environments.
With its advanced contact seal and ability to accommodate static shaft misalignment, the Sealmaster RPB bearing kept contaminants out and performance high. After five weeks in continuous operation, the bearing showed no signs of wear – far outperforming the previous solution.
This upgrade resulted in over US$50 000 in savings from reduced maintenance and replacement costs, while significantly improving conveyor uptime. With features like a unitised, replaceable cartridge insert, durable cast iron housing, and multiple sealing options, the Sealmaster RPB bearing is built to thrive in the toughest conditions.
