ASB cast bronze standards are general-purpose bearings that provide the best mix of functional properties, availability and economical cost. They offer excellent load carrying capabilities with good anti-frictional properties. They can perform over a broad range of temperatures (up to 450°) and can readily be modified with grease grooves, oil grooves or self-lubricating graphite plugs.

All standard stock sizes are also available in other materials such as no-lead bronze, aluminum bronze, and manganese bronze. Special requests are welcomed with flexible stocking arrangements or just in time delivery schedules.
