INNOVATIVE FEATURES:
NON-ROLLOVER CAM
- Provides higher torque ratings than the leading competitors due to the larger profile and greater contact area.
- Improves performance and prevents costly and potentially dangerous rollover.
>
SPECIAL LABYRINTH SEAL
- New seal design prevents the ingress of dust and other contaminants typically found in mining and cement plants, which extends the life of the lubricant.
- Minimizes heat generation and provides trouble-free service with minimal scheduled maintenance.
>
Superior Performance in the Harshest Environments
GREASE LUBRICATION
- Offers synthetic grease lubrication in a sealed backstop design.
