Increasing industrial demands on lubrication greases for high-speed and high-temperature applications on rolling bearings represent a tremendous challenge for grease manufacturers. Lubricating greases developed for these kinds of applications should offer what they promise. The challenge is to check that these promises are fulfilled. Current test methods do not have the flexibility to allow tests to be conducted under variable conditions with respect to speed, load and temperature, or while simulating the customer’s application. This is why SKF developed its own grease testing machine in order to determine the most suitable grease to
ensure the best possible performance for SKF high-quality bearings. The SKF Grease Test Rig RHF 1 is now available on the market.
The SKF Grease Test Rig RHF 1 essentially consists of three parts – a mechanical test unit, an electrical cabinet which incorporates the PC, the keyboard and the screen, all control functions for the test mechanics and an external cooling system supporting the high-speed spindle drive.
All important parts of the machine can be accessed from the front side. Various test bearings can be used (see technical data).
For the shielded bearings, the shields are delivered separately. The high-precision shaft is rotated by a frequency-controlled high-speed spindle drive. The cast iron housing contains two heating elements.
Each half of the housing has a temperature probe to check and regulate the temperature.
