U-Groove™ - Greater load surface!
A unique oil groove design with a 90° groove shape. U-Groove™ increases bearing load capacity by expanding the surface area, while keeping oil flow capacity intact.
- Better load distribution across the bearing surface
- A more stable hydrodynamic lubrication regime
- Greater bearing durability at high RPM's

Bull's Eye Tolerance™ - Perfect clearance in every set!
Sets new standard in bearing thickness consistency and outperforms the industry’s wall thickness tolerance, ensuring the least thickness variation shell-to-shell
- No more multiple set purchases or “fishing” for bearings to reach right clearance
- No need to grind cranks “fat” or “thin”
- No need to adjust housing diameter
- Less taper across the bearing face

ElliptiX™ - Improved oil ingress!
Is newly designed oil slot/oil hole hybrid that improves oil ingress, without affecting the bearing’s surface. The innovative changes to the slot hole prevent a compromised load capacity.
- Increases oil passage capacity
- Produces higher oil supply reliability
- No need for custom-made oil hole enlargement

RadiaLock™ - Optimal crush height and heat transfer!
Is an optimal crush height value obtained from an optimization process that customizes each bearing crush height to its specific performance demands.
- Optimal press fit
- Improves bearing spin and fretting prevention
- Better heat transfer
- Reduces bearing and housing distortion

EccentriX™ - Superior hydrodynamic regime!
Is an optimized eccentricity value reached through elasto-hydrodynamic analysis and dynamic calculations. Each bearing’s eccentricity value is custom designed to meet specific performance requirements.
- Better oil wedge formation
- Stable hydrodynamic lubrication regime
- Minimized vibration and wear
- Prevention of oil film “wiping” in high RPM conditions
- Optimal load distribution across bearing surface
