Bellows flex CHP

Bellows flex CHP

Resin bellows employed in pursuit of flexible and low inertia.

· Using resin boots absorbs vibration.
· Compact design with integrated hub and boot, with no backlash.
· Coupling with extremely small shaft reactive force owing to vibration absorption or installation error, suitable for stepping motor, encoder, etc.
· Conforms to "RoHS" EU Directive, prohibiting the use of 6 hazardous chemical substances such as mercury and lead.
