- Cement Plants - used in bucket elevators and inclined conveyors for moving limestone and clay to crushers and silos.
COMMON INDUSTRIES
- MINING
- POWER GENERATING PLANTS
- CEMENT
- PORTS
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.
- Breather element is eliminated.
