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
