Housing Flange Specifications

Spyraflo Aluminum Housing Flanges come with a choice of Self-Aligning Bearings.  Combining the light weight, clean lines, and dimensional consistency of sintered aluminum with the load carrying
capability of Needle Roller Bearings, Teflon-Bronze Bearings, or SAE 840 Bronze plain bearings, our Housing Flanges are often able to replace more expensive, larger and heavier weight cast iron / ball bearing assemblies.  The low profile of the Spyraflo Housing Flange, is a benefit and a simple solution to often-expensive Housing Flange Block mounting challenges.

Housing Flange Features:

• Lightweight and Corrosion Resistant
• Low Profile / Economic Option
• Bronze option is a drop-in replacement for the Bunting Lube-Align
