Male connector
Low torque rotation style
Rotary One-touch fittings
Applicable to use for oscillating
and rotating sections in robots.
Brass parts are all electroless
nickel plated.
Thread sealant is standard.
2.1-31
Slide bearing
Smooth operation and longer life from an oil
containing slide bearing.
Rotary seal
A special rotary seal minimizes friction while
providing an excellent seal.
Holder
Standard nickel plated allows copper-free
applications.
Ball bearing
A ball bearing ensures low torque rotation.
Stud
Threads are coated with a Teflon
sealant for quick assembly.

an excellent seal.
Seal is fire and
shock proof fluo-
rine rubber. Proves
against high friction heat
in high speed rotation
and longer life.
