3W FHUBX3 1/4

features

• Unique tooth form uses a 40° pressure angle and distributes the load over a larger area than couplings which use a 20° pressure angle
• Quality exposed fasteners consist of SAE grade 5 bolts with hex nuts and lock washers
• Clear rust inhibitive and corrosion-resistant finish protects coupling in normal industrial environments
• Sizes 1 through 7 compensate for up to ± 1 1/2° static angular misalignment per gear mesh
• Optional pilot rings provide positive register between identical halves (eliminates selective assembly required in male, female sleeves)
