Hoffmann Brass Cage Bearings
Hoffmann Brass Cage Bearings are first choice in industries such as petrochemical where unexpected failures can be catastrophic. Brass lends itself to preventative maintenance programmes, where vibration monitors are used to get early warning of potential failures. This is possible because brass fails very gradually, giving indication of failure along the way. In contrast, polyamide cages do not lend themselves to vibration monitoring programs and pressed steel cages can fail catastrophically without warning. This is the major reason why operators of petrochemical plants have replaced pressed steel and polyamide cage bearings with brass caged split roller bearings.
