Emcor Grease Testing Machine
Catalog/Part Number:: K9440
Description
Test
Method
Measures
the ability of a grease to protect a bearing against corrosion in the presence
of water. Two sets of grease-coated bearings per station are partially immersed
in water and rotated at a speed of 80 rpm in a sequence of running and resting
periods. At the end of the test, the raceways of the bearing outer rings are
inspected for rust.
Features
- Evaluates
the rust preventive properties of greases and oils
- Performs
both standing and dynamic testing
Description
The
Emcor Grease Testing Machine evaluates the rust preventive properties of greases on bearing components, measuring the ability of a grease to
protect a bearing against corrosion in
the presence of water. As bearings are normally used in environments exposed to humidity and temperature variations, condensation may form on the bearing thus promoting the onset of rust.
Rust is detrimental to proper bearing operation and will compromise the
longevity of the bearing. A good quality
grease should be designed to protect the bearing from rust and corrosion under these conditions. The Emcor system features test method versatility, since both greases and
oils can be tested as well as variations can be made with regard to the test
medium (e.g., brine instead of
water). The costs for running these tests are minimal. The two test bearings are the only machined parts that have to be renewed
for each test, and the polyamide material for the housing is rigid and strong
and rarely ever needs replacement.
