Materials (Bronze Alloys)

viiplus offers growing products of engineered self-lubricating bearings and graphite lubricating bearings products and services to keep industries moving efficiently and reliably.

Graphite is a dry form of lubrication that reduces friction between two metal surfaces. This form of lubrication can withstand higher temperatures than liquid or oil-based lubricants. Graphite is accomplished by grooving the ID face of the bearing and then pressing graphite into the cavities under extremely high pressure. Graphite is often used in bearing lubrication for hard-to-reach places that cannot be lubricated manually.

Diversified Bronze is skilled in the use of graphite as a lubricant in custom machined parts such as bushings and bearings.

We can assist you with everything from engineering advice to building your sliding bearings prototypes. And when it comes to oilless bearings material selection, we have one of the widest selections of products available today.

Custom Bearing Solutions

Custom Quality Cast, Groove, & Self-lubricating Bearings

graphite plugged BRONZE BUSHINGS

Graphite – Graphite lubrication on the I.D. face of the bearing will enable you to obtain long bearing life both at high operating temperatures and in applications lacking supplemental lubrication. Graphite is accomplished by grooving the I.D. and then pressing graphite into the cavities under extremely high pressure. A film of lubricant is transferred to the shaft as it starts to turn.
