Description

The type RT-CRM Series is coolant rotary union required to transfer fluids from stationary to rotating machine parts in case of complex applications such as machine tools. High speed around 15000 RPM and high pressure around 50 Bar needs rotary union that suits in this operating condition. Thus RotaTech offers complete range of rotary union and sealing system that suits individual needs and specification. Well balanced seal assemblies in carbide allow a low friction torque and long life even with a poor filtration of the coolant. The low torque feature makes this series ideal for high speed applications.

We also manufacture and supply  Air Vacuum Rotary Union, Multi Passage Rotary Union and Water Rotary Union as being topmost Rotary Union manufacturers in Mumbai as well as known as one of the most precise rotary Union manufacturing companies in India.

FAQ

  • It transfers coolant from a stationary supply to a rotating spindle or shaft.
  • Commonly used in CNC machines, machining centres and other rotating equipment.
  • It helps maintain continuous coolant flow during rotation.
  • Check coolant type, pressure, flow rate and RPM.
  • Shaft/thread size and mounting arrangement must also match.
  • Sharing your machine model, existing union details or drawing helps in selecting the correct unit.
  • Mount the rotary union according to the specified shaft and thread dimensions.
  • Connect the coolant inlet and outlet correctly.
  • Ensure proper alignment and avoid excessive side load on the union.
  • After installation, check for leakage before running at full RPM.
  • Yes, a suitable replacement can be provided for many existing brands.
  • You can share the old rotary union model number, dimensions, photo or drawing.
  • The replacement can then be matched according to fitting and operating conditions.
  • The maximum pressure and RPM depend on the model, seal design, coolant and application.
  • High-pressure and high-speed applications require the correct rotary union specification.
  • Provide your operating pressure, RPM and coolant details for proper selection.
