24 Aug A full-service solution package for copper mine
When CBC Regional Mining Manager, Sam Wilkinson, received a query from a copper mining customer in Northern Queensland about a bearing failure analysis on one of their flotation blowers, he moved quickly to draw up a proposal that included an NTN bearings solution.
“The fans move at very high speeds, and in this case the spherical roller bearings the customer was using on the fan were slipping due to poor axial and radial loading, causing bearing failure every 8-12 months,” explains Sam.
The Queensland engineering team suggested using a pair of NTN Angular Ball Bearings (7226) for the shaft to reduce skid, and a single NTN Deep-Groove Ball Bearing (6226) for a smoother barrel assembly.
