Bronze bearings handle higher temperatures

Unimatic Engineers is introducing a range of bronze bearings for use in commercial ovens and other applications subject to constant or intermittent high temperatures. A development of the patented self-clinching and self-aligning bearings developed by Spyraflo in Florida the new high-temperature plain bearings are available in graphite bronze as standard and Teflon bronze for high load carrying capacity. Applications that would benefit from these bearings include commercial ovens, particularly those in fast food establishments and institutional kitchens as in hospitals, schools etc. Also, OEM equipment manufacturers often use a powdered paint process that heats surfaces to temperatures in excess of 200C. This 'baking' process necessitates bearings that can withstand high temperatures. Although standard Spryraflo bronze bearings can be used in temperatures reaching 190C, the new line of high temperature bronze bearings can go up to 280C. For self-clinching, Spyraflo bearings incorporate a serrated flange and outer profile of the bearing, encouraging 'cold flow' into the sheet metal as the bearing is pressed into the material. This simplifies the assembly process and results in a bearing that withstands shock, vibration and side load. Additionally, a self-aligning capability ensures smooth shaft rotation. The self-clinch, self-align design is available in sizes of 6, 8, 10 and 12mm. They can also be clinched into a standard two-bolt hole steel flange, forming a flange-mount with self-aligning capability, ready mounted and perfect for applications requiring subsequent replacement or adjustment.
