What is a BowMet® flanged bearing?

A BowMet® flanged bearing is a heavy-duty plain bearing manufactured from ToughMet® spinodal bronze with an integrated flange to support both radial and axial loads. Designed for demanding industrial applications, it offers exceptional load capacity, wear resistance, and corrosion resistance while providing accurate component positioning.

Why choose ToughMet® spinodal bronze?

ToughMet® spinodal bronze delivers one of the highest load capacities of any proprietary plain bearing material. It combines exceptional strength, outstanding wear resistance, excellent corrosion protection, and resistance to galling and fatigue, making it ideal for severe-duty applications where conventional bronze bearings may wear prematurely.

What sizes of BowMet® flanged bearings are available?

BowMet® flanged bearings are available in a range of standard sizes to suit many industrial applications. For projects requiring non-standard dimensions, Bowman can manufacture bespoke bearings to meet your exact design and performance requirements.

Can I order custom BowMet® flanged sizes with grooves or oil holes?

Yes. Bowman offers bespoke manufacturing services for BowMet® flanged bearings, including custom diameters, flange dimensions, lubrication grooves, oil holes, and other application-specific features. Our in-house engineering team can manufacture bearings to your drawing or specification.

Which industries use BowMet® flanged bearings?

BowMet® flanged bearings are widely used in mining, construction, marine, oil and gas, agriculture, power generation, material handling, and heavy industrial machinery. They are particularly suited to high-load applications where long service life, corrosion resistance, and reliable performance are essential.
