time. If application needs dry running, please consult factortime. If application needs dry running, please consult factory.
INSTALLATION
- Do not connect Rotary Joint directly to piping. Rotary Joints are
designed to float with the flexible hoses.
- Install hose with curve in direction of rotation.
- Unless specified, all 50 Series Rotary Joints are shipped as P-type.
- All 50 Series Rotary Joints has a standard P type housing. S type
and RSP type joints consists of P-type housings with the appropriate
elbow (S or RSP) type.elbow (S or RSP) type.
- Always flood the Rotary Joint and purge any entrapped air in the

- 50 Series Rotary Joints are equipped with composite or bronze
bearing which are self lubricating which does not need lubrication for life.
- 50 Series Rotary Joints are maintenance free.
- Before maintenance, allow the machine and media to cool down.
- Be sure that no feed pressure is applied.
- If the rotary joint is defected and leaking occurs, replace seals with new ones and do not work with
leaking joints.
MAINTENANCE
1. First hold the housing of the joint with a bench wise. Do not clamp
too tightly, it will damage housing or bearings.
2. If the joint is used for single flow, apply adhesive or teflon tape to the
threads of the pipe plug and assemble it to the second port of the joint.
3. If the joint is used for dual flow,
3.a) For S Type; apply adhesive or teflon tape to the thread of the
siphon pipe and assemble it to the dual flow elbosiphon pipe and assemble it to the dual flow elbow.
3.b) For RSP Type; apply grease inside the bronze bearing in the
dual flow elbow and assemble siphon pipe gently inside the bearing.
3.c) Apply adhesive or teflon tape to the thread of the dual flow
elbow. Becareful when assembling dual flow elbow with siphon pipe
to the second port of the joint, internal siphon pipe may damage
internal parts of the joint.
4.4. Apply sealant/adhesive or teflon tape to the threads of the hoses
and assemble them to the housing.
5. If housing connections are SAE Flange, place o-rings into the
grooves and fix flanges of the hoses with appropriate bolts.
6. Clean machine bore surface before assembling.
7. Apply adhesive or teflon tape to the threads of the shaft and install
the joint to the machine. When installing, pay attention not to install
eccentricalleccentrically.
8. If the joint shaft is quick release; put a new copper washer into
the bore of the roll, assemble qr flange onto the shaft, place split
rings onto the socket on the shaft correspondingly, place qr flange
onto the split wedges and fix the flange to the bore of the roll with
appropriate bolts.
9. Connect hoses to the supply and return lines. Use flexible hoses
and never install joint directly to the pipes.and never install joint directly to the pipes.
10. After assembly; control rotation of joint. If any wobble, vibration,
knocking or noise show up or if any eccentricity seems; disassemble
the joint from the machine and assemble it again.
