K Series are multi-way rotary joints designed for middle and high speed high-pressure applications. They are used on machining center revolving tables, hydraulic workstations, coiling machines, wind generators, centrifugal machines and etc. ial carbon steel. If other material is required, please inform beforehand.
Main Features:
Supported by double high-precision maintenance-free bearings for high stability.
Special sealing structure designed for high-speed and high-pressure application that provides prolonged failure-free operation.
Low rotation torque.
Special structure to be free from friction heat under high speed.
Running torque unaffected by working pressure and temperature change.
Max working speed up to 6500RPM.
Drainage hole design to avoid exterior contamination.
Customization available for different customer applications.
Technical Ratings
Max Speedï¼?6500 r/min Temperatureï¼?-30ï½?+80
Max Pressureï¼?30Mpa Mediaï¼?Hydraulic Oil
Notes:
1.K Series use labyrinth sealing structure. During installation and operation, the drainage hole L must be connected by oil pipe to the oil collection tank. And the oil pipe must not be blocked to avoid back-pressure.
2.Inner leakage is allowed between each passage. Please pay attention to the compatibility of different working media to avoid crossed contamination.
3.The working fluid or hydraulic media should be filtered before being ued. The filtration precision should be no lower than 10um.
4.Working temperature rise will reduce the viscosity of the working fluid to increase the leakage volume. So during operation, cooling device should be accompanied.
5.The hydraulic system should be equipped with automatic pressure regulator to compensate the pressure loss caused by inner leakage.
The RF/DF mechanical chuck is designed with three large external sliding chunks, while it uses the cam structure inside. The expansion of the sliding chunks is done by the pushing of the cam structure, and the expanding sliding chunks then tighten the paperboard core and realize self-centering.
Main features:
Shaftless design for quick and efficient reeling and unreeling.
Excellent paperboard core holding and tightening realized by the sliding chunks with large contact area
and high stability, to avoid problems such like slipping, loosening, core breakage and etc.
The locking force reinforced by special convex-concave texture of the sliding chunks.
The cam structure provides even clamping force by use of self-weight.
Maintenance-free structure with low friction force.
Special excellent alloy steel material is adopted with great durability for high load capacity.
Excellent paperboard core holding and tightening realized by the sliding chunks with large contact area
and high stability, to avoid problems such like slipping, loosening, core breakage and etc.
M Series are multi-way rotary joints designed to carry multiple media continuously for low-speed and high-pressure equipment. They are used on machining center revolving tables, rotating platforms, coiling machines, converters, ladle turret, hydraulic machinery, multi-way high pressure controller and etc.
Main Featuresï¼?
Supported by double high-precision maintenance-free bearings for high stability.
High-quality imported sealing parts for prolonged service life.
Stainless steel rotor with special treatment to provide good durability.
Housing material available in aluminum, stainless steel or brass.
Special leakage reflux design to avoid exterior contamination.
Customization available for different applications.
Technical Ratings
Max Speed:300 r/min
Temperature:-30+80
Max Pressure:30Mpa
Media:Hydraulic Oil ,Air ,or similar
Notesï¼?
1.Operation under extreme ratings should be avoided. Maximal working speedis in reverse proportion to working pressure, and is also influenced by the media lubricity and the heat dissipation ability of the sealing components.
When the rotation speed is lower than 10RPM, the maximal pressure can be up to 30Mpa.
2.Inner leakage is allowed between each passage. Please pay attention to the compatibility of different working media to avoid crossed contamination.
3.The working fluid or hydraulic media should be filtered before beingused. The filtration precision should be no lower than 10um.
4.Drainage hole is accompanied for observation and collection of escaping media.
5.For other applications, please consult us beforehead.
Main Features:
Split structure and ready repair kit for easy maintenance and repair.
Double imported high-precision ball bearings for high stability.
Balanced mechanical sealing structure for prolonged service life.
Standard Sic/Carbon Graphite sealing pair for good sealing performance.
Optional Sic/Sic, Tungsten carbide/Tungsten carbide and other sealing pairs for strict environment.
