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.
No need to monitor oil levels, refill the backstop or worry about moisture in the lubricant.
Provides trouble-free performance with minimized maintenance requirements.

DROP IN DESIGN

Tsubaki offers the narrowest backstop with an I-beam torque arm.
Quick and easy field replacement. Drop in compatible with most competitive products.

3 STEP
EASY CONNECTION
