Aerospace Bearings Heaters

The UNASIS Aerospace Bearing Heater comes with several features and advantages, including:

• 100% Heating Control
  • By accurately regulating power, the new Aerospace Bearing Heater offers easy, operator-friendly input for both the required and maximum temperature between the inner and outer ring.
• No Magnetism
  • Magnetism can lead to undesired bearing vibration during applications and drastically reduce service life. To combat this, UNASIS Aerospace Bearing Heaters are designed to not cause any magnetism.
• Touchscreen Interface
  • An intuitive user experience with a state-of-the-art touch screen user interface.

The UNASIS Aerospace Bearing Heater offers the following benefits and features:

• Precise Temperature Control with 4 heating options
• Separate temperature probes on both the inner and outer rings to monitor the temperature differential between the races and automatically regulate power accordingly
• The UNASIS Aerospace Bearing Heater removes the costly False Brinelling during assembly. In addition to the temperature control over the inner and outer rings, false brinelling due to a thermal expansion mismatch does not occur, protecting your investment.
• Creates Proof of Work Reports
  • Excel-formatted reports are produced to demonstrate that flight critical bearings were installed correctly.
  • Download data directly to the USB for graph creation to show the rate of heat for every component.

The inner ring heats up and expands faster than the outer ring when a bearing is heated in a conventional bearing heater or oven. When using an oven, there is no method to control the thermal expansion differential, which can lead to false brinelling occurring (or minor indentations on the raceway) and can sometimes exceed the bearing clearances. As discovered by a variety of equipment and machinery manufacturers, this can lead to premature bearing failure in application. In addition, it is impossible to see what is happening in an oven, leading to ‘hot’ and ‘cold’ spots being undetectable which can greatly damage bearings whilst remaining unseen until they reach their in-service destination.

As bearings can occasionally show unwanted in-service vibration when magnetised, our Aerospace Bearing Heaters are developed to produce no magnetism throughout operation. The heaters have been designed to provide users with a practical yet simple and precisely controlled method of heating up highly-priced bearings. The recording, data collection, and storage facility features of the Aerospace Bearing Heaters provide the ability to hone bearing heating to another level.

Proof of work reports in Excel formats can be stored and issued with data readily downloaded onto a USB stick detailing temperature differential between the two rings. With state-of-the-art touch-screen technology, it can be ensured that the maximum temperature differential can never be reached as our Aerospace Bearing Heaters can be set to automatically control temperature ramp up rate in real time. This data is collected as the rings are heated, with the option for users to graph this against time on a chart when making proof of work documents.

The UNASIS Aerospace Bearing Heater has separate temperature probes (one each on the inner and outer bearing rings) to ensure complete control and accuracy whilst stopping any deterioration of the bearing during the heating process. Not only does this allow users to assess the optimal temperature on either ring, it automatically adjusts the temperature ramp-up rate in real time to never exceed the maximum temperature differential. This removes the chance of differential thermal expansion leading to reduced performance and service life being caused by false brinelling.

The majority of bearing applications within the Aerospace industry can be supported by three different UNASIS Aerospace Bearing Heaters. The maximum weights possible are 50kg/110lbs, 150kg/330lbs, and 200kg/440lbs.
