Rotary Joint

Clearance seal type MFC type

There is no seal lifetime because this is non-contact seal type.
Furthermore, it is low heat generation and low dust emission.

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) 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.

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) ESX20M-S&E series

2 fluid type (Coolant and oil mist).
Applicable for hollow motor and built-in spindle.

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

2 fluid type (Coolant and oil mist).
Minimum length type.
Applicable for M10 rotor.

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.

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) LX88 series (Hexagonal connection)

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 (Octagonal connection)

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

For turning machine for chucking (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 for chucking (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.

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 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.

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: Steel NJ type

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

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.

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.

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.

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).
