Jackson Brothers Coupling
1/4" Shaft
(SHW) 5610
2 kv Jackson Brothers English flexible shaft coupling is great for those small jobs not requiring much torque, voltage withstanding or alignment correction. 3/4" diameter. Plastic dielectric has hole in center allowing shafts to touch if fully inserted or seperate for maximum voltage breakdown. 1/4" shaft both sides.
$15 each - $12 (10+)
Ceramic Coupling
1/4" Shaft

Flexible
(SHW) 39009
Millen coupling rated at 7 kv but we have used them successfully to 15 kv. Flexible but with 250 Oz./In. maximum torque. Self-aligning coupling adjusts for up to 13% angular shaft misalignment by flexing. 1-5/8" diameter. Open center allows user to set shaft separation.
$72 each - $67 (6+)
Ceramic Coupling
1/4" Shaft
(SHW) 39006
Millen coupling rated at 2 kv but we have used them successfully to 5 kv. Flexible but with 140 oz. / in. maximum torque. Self-aligning coupling adjusts for up to 13% angular shaft mis-alignment by flexing. 1-1/16" diameter. Adds 3/16" length in shaft separation.
$27 each - $25 (6+)
