Industrial Bearing Support Brackets

Triangle manufactures three- or four-arm style spider blower bearing brackets for the HVAC industry

Bearing support brackets facilitate accurate positioning of the shaft and blower wheel through its self-centering and self-aligning design. Our bearing frames are stamped from galvanized steel and then welded or crimped together to produce the entire assembly. We offer both universal brackets and custom-made blower bearing brackets to your specification.

Advantages of Triangle’s spider bearing brackets:

  • Preassembled or unassembled based on your shipping preference
  • Customizable lengths and gauges for maximum flexibility
  • Rigid assembly reinforces the strength of the blower side sheet
