Oil Grooves vs. Grease Grooves
Oil Groove Bronze Bearings
Oil Groove Bronze Bushings

Grease grooves are typically wider and deeper than oil grooves. This is to hold a supply of grease and to provide for the thick grease to be forced in. Oil grooves typically vary in width but are shallower than grease grooves. Most oil grooves are operating in a constant loss or closed oiling system that continually feeds the less viscous oil to the grooves. Double loop groove & double figure eight groove recommended for grease only.

Graphite Bronze Bearing
Maintenance-Free bronze bearings and wearplates with graphite filled grooves and graphite plugs are available. The graphite acts as a dry lubricant and provides maintenance-free continuous lubrication. The ID groove patterns can be filled with a special hardenable graphite paste. Graphite Plugs can be press fit through the wall of the bearing with a special epoxy resin binder. Typical plug diameter is 7mm with a 25% surface coverage. The graphite plugs can be placed around special features of your parts. Graphite bronze parts should be run dry with no oil or grease. Our graphite plug bearings typically have a coefficient of friction between 0.10 and 0.15, depending on a variety of factors affecting performance.

What's Driving
Metal Prices

Factors creating the on-going surge in copper prices and base metal prices.

The U.S. imposed a 50% Section 232 tariff on the copper content of semi-finished and derivative copper products, effective August 1, 2025. These tariffs aim to bolster domestic production but create complexities for businesses in pricing, sourcing, and compliance, affecting global copper markets. 

In addition copper costs are soaring due to massive demand from the energy transition (EVs, renewables, grid) and AI data centers colliding with slow mine supply growth, production disruptions (labor, technical issues), aging mines, and government policies like tariffs, creating a structural supply deficit. 

Tin prices jumped to a record level due to a severe, ongoing global supply squeeze from mine disruptions (DRC, Myanmar, Indonesia) and increasing demand driven by its critical role in electronics (solder), green energy tech, and packaging, creating a significant market deficit and attracting speculative investment. Supply chain issues, including export permit delays and political instability in key producing regions, combined with growing recognition of tin's necessity for the energy transition, fueled a rally to multi-year highs in late 2025 and early 2026. 

Nickel prices are rising due to anticipated supply cuts from major producer Indonesia, tighter quotas, increased demand from stainless steel and EV battery sectors (despite some LFP shifts), speculative buying, and broader market strength in metals, with investors reacting to policy signals and potential disruptions.
