Century Arm & Cone Advantages
- HSN O-Ring Seals – For the high energy required, Century has designed and utilizes the largest seal in the industry. HSN Material utilized for wear, heat compression and chemical resistance properties.
- Premium Crowned Roller Bearings – Gives the bearing the capability to withstand the extreme high loads.
- Premium Floating Thrust Bearing – Allows for reduced frictional heat build-up to ensure lower operational temperatures under high-energy operations. This design facilitates the longer bit life Century’s reputation has been built around.
- Gage Row Protection – Double the number of carbide inserts that actively cut the gage diameter and assist in maintaining tight tolerances and extending in-gage bit life.
- Shirttail/Leg Protection – Hard Facing along with carbide inserts blanket the shirttail and leg providing superior wear resistance.
