Rotary Joint

Rotary joint is a rotating connector to supply hydraulic/pneumatic pressure and/or coolant liquid from outside to a jig on a CNC rotary table. If liquid is supplied with ordinary hoses or cables, twisting will happen on them by rotation of the table. However, rotary joints can solve this problem as it rotates in accordance with the table.

Rotary tables with external rotary joint

Functions and features ・ On rotary tables with external rotary joint, the rotary axis rotates in accordance with the table. ・ External rotary joint can be set on a CNC rotary table after it is purchased. ・ Advise fluid to be used, pressure, number of port and dimensions. ・ Special size can be manufactured in regards to customer’s request.
