Tungsten Carbide Radial Bearings
The Optimist Advantage
Optimist is a privately owned company focused on engineered sourcing. We do not sell motors, we do not do directional work. We specialize in high performance bearings.
The Right Solution, Faster
A large manufacturing capacity enables us to deliver custom radial bearing solutions for a wide variety of applications with fast lead times.
Smaller is Better
Smaller diameter tungsten carbide inserts provide excellent hardness, wear properties and resistance to cracking under impact loads.
Strategic Spacing
Insert spacing has been optimized to deliver high carbide content while retaining outstanding toughness and resistance to cracking / flaking.
Superior Processes
A reliable infiltration process produces exceptional metallurgical bonding between the base metal, inserts and matrix.
Material Selection
Inserts boast a carbide content above 90%, while a high-carbide content matrix material delivers high wear and erosion resistance.
