applications
- Can be used to directly connect any two shaft ends from 1/2" to over 4" in diameter on centrifugal pumps, small compressors, blowers, conveyor drives, fan drives, and all other similiar medium-duty, moderate-speed applications
- When driving and driven shafts are widely separated, an unsupported or floating shaft is used to the span the gap. The two couplings required at each end of that shaft consist of one half of a standard coupling bolted to a Rigid Hub, each unit called a F
features
- All-metal end ring seal design for maximum service life. The industry standard for over 75 years.
- Provides 300% greater lubricant capacity than o-ring style couplings.
- Greater lubricant capacity allows longer periods between scheduled lubrications and longer service life.
- Straight tooth design provides improved load distribution, lower stresses and longer life for the gear teeth.
