Four Ball Tester | 4-Ball Wear Tester - Rtec Instruments

The tester comes with close loop down force control. This allows to apply up to 10,000 N load using motors (using no dead weights). 4 ball wear or 4 ball EP tests are automatic and very easy to use. In-line torque, friction, and acoustic signals automatically calculate the test results. The tester also creates quick screening methods.

Plate Load Testing | Plate Bearing Tests - Site Testing Services LTD

If the plate bearing test is carried out below the groundwater level, it is essential to lower the groundwater level by a system of wells or other measures outside and below the test position. The preparation of the test surface may cause an unavoidable change in the ground stress which may result in irreversible changes to the subsoil properties.

Engine Oil Viscosity and Bearing Wear: Field Test Results - SAE …

1/10/1992· These results were used to design a Field Test of nine oils in 45 taxicabs in New York City. The test oils (SAE OW-20 to 20W-20) were formulated to measure the effects of viscosity, viscosity index improver, and detergent inhibitor package. Bearing wear tended to be either low and unremarkable or very high, particularly in the thrust bearings.

30/1/2022· These peaks correspond to the ball bearing pass frequencies for the motor bearing. In the high-range spectra, harmonic markers are placed on each peak of the harmonic series with 4.9xM spacing. Note that the harmonic series has strong amplitudes in all three axes of the high range while only prominent in the axial direction in the low range data.
