MF Coupling Series

NIHON MINIATURE

Low cost coupling that uses zinc die casting for the hub part (boss part), and urethane rubber for the sleeve.

[Features]
· MF coupling consists of one rubber sleeve and two hubs made of zinc die-cast (surface treated).
· Sleeves and hubs have splines on inner and outer diameters, respectively, which engage and transmit torque.
· Fastening to shaft is by set screw.
