Rotary Joint

Applicable industry: Machine tools (Built-in bearing type) LX84M, 86M series

2 fluid type (Coolant and oil mist).
This rotary joint achieves longer lifetime because double drain structure prevents entering drain to bearing.

Applicable industry: Machine tools (Built-in bearing type) LX84V, 86V series

3 fluid type (Coolant, oil mist and dry air).
This rotary joint achieves longer lifetime because double drain structure prevents entering drain to bearing.

3 fluid type (Coolant, oil mist and dry air).
Bore-mounted type.
Applicable for high pressure and high speed.

Applicable industry: Machine tools (Built-in bearing type) LX88 series (for octagonal shaft)

3 fluid type (Coolant, oil mist and dry air).
Bore-mounted type.
Applicable for high pressure and high speed.

Applicable industry: Machine tools (Bearing-less type) ESX20M-S&E series

2 fluid type (Coolant and oil mist).

Applicable industry: Machine tools (Bearing-less type) ESX20M-13060, 61, 62

2 fluid type (Coolant and oil mist).
Easy install rotor.
Enables smooth movement of the stationary seal.
Superior sealing and durability performance.

Applicable industry: Machine tools (Bearing-less type) ESX20M-L series

2 fluid type (Coolant and oil mist).
Maximum stroke (axial movement) is 8 mm.
Seal type is "Heat shrink fit" that prevent seal separation by chemical influence of coolant.

Applicable industry: Machine tools (Bearing-less type) ESX20V-L series

3 fluid type (Coolant, oil mist and dry air).
Maximum stroke (axial movement) is 8 mm.
Seal type is "Heat shrink fit" that prevent seal separation by chemical influence of coolant.

Sludge adherence reduction type (Auto Flush)

The "Auto Flush" system developed by RIX reliably reduces "leakage" which has been a major problem with rotary joints for machine tools.

This system is a new technology that dramatically improves the biggest factor that causes leaks (opening/closing operation failure caused by sludge contained in coolant).

Applicable industry : Machine tools (Switching valve with ejector function) "Cln Vac"

・Suction of residual coolant inside the machining center spindle.
・Mist control inside the machining chamber.
・Reduction of air consumption during ATC.

For ball screw cooling (Bearing-less type) ES50 series

One rotary joint is able to supply and discharge coolant oil.
Easy to control heat generation and saving motor energy comparing with oil seal type.

For turning machine chuck (Built-in bearing type) LA1P series (Single port)

No oil air supply needed for dry air use because grease is enclosed at mechanical seal part.

For turning machine chuck (Built-in bearing type) EES-2P03 (Double ports)

No oil air supply needed for dry air use because grease is enclosed at mechanical seal part.

Applicable industry : Machine tools (for table cooling) Multi-port series

Suitable for various applications such as chucking, mating detection, air blow, and coolant-through.Supports high pressure and high-speed rotation.

Applicable industry: semiconductor (for pure water / chemical / slurry) single port

Reduces elution of metal ions into the fluid with non-metallic internal wetted parts.

Applicable industry: semiconductor (for vacuum chuck for wafer holding)

Low heat generation and minimal dust emission thanks to the clearance seal.

Applicable industry: semiconductor (for slip ring)

Slip rings can be combined thanks to hollow interior.

Applicable industry: semiconductor (for cooling table)

A hollow hole can be drilled in the center of the rotary shaft of a rotary joint.

Applicable industry: semiconductor (for CMP equipment)

Multi-port type suitable for simultaneous supply of multiple fluids (3 ports). Rotation without fluid is possible.

Applicable industry: Steel NJ type

Material of this rotary joint is stainless steel that are superior to corrosion resistance.
Therefore, these parts rarely need replacement.

For water and hot water (Applicable industry: General machinery) LC type

There is no seal force trouble caused by accumulated contamination in the fluid and water scale on spring part because spring for seal force is not in the fluid.

Applicable industry: Rubber and tire NB type

This rotary joint is superior to environmental resistance because material of main parts is Cu alloy and Stainless steel.
Maintenance free and no oil supply is needed.

Multi-port type (3 ports or more) MF type

Multi-port (3 ports or more) rotary joint is order made base.
Our proposal of rotary joint is based on customer requirements such as pressure, rotation speed, temperature, fluid type, number of ports and port size.

For hot water and heat transfer oil (Applicable industry: General machinery) LCH type

Applicable for maximum temperature 200 ℃ because packing and grease have heat tolerance.
Furthermore, no regular oil supply is needed.

Applicable industry: Paper V type

Adopted dry bearing (guide bearing) that is strong for vapor.
Material is no oil supply type and no baking trouble.
