Standard tests for determining resistance of grease in the

bearings against water washout run at test temperatures

of 38 °C and 79 °C under defined laboratory conditions

[25]. The tests differ from other field tests in the

operating conditions. The principal scheme of the test

rig conforming to the standards DIN ISO 11009, DIN

51807/2 and ASTM D1264 is shown in the Figure 10.

For running the 60 min. test a grease lubricated open

deep groove ball bearing 6204 is mounted into housing

and rotates at 600 rpm. Amount of grease in the test

bearing is 4 ± 0.05 g. Water jet is sprayed onto the

bearing with the flow rate 5 ± 0.5 cm3/s. The average of

the duplicate tests amount of washed-out grease is a

measure of its water resistance. A general view of the

new design of the machine implementing these tests is

shown in the Figure 11.

The up-to-date tester possesses the following

features and advantages: advanced control and sensor

technique; electronic data acquisition; user friendly

operation and maintenance; two separated water tanks

(Fig. 12) for duplicate or independent testing; two speed

levels 600 rpm and 3780 rpm, while variable speed

control is optionally possible too; test temperature up to

80 °C enables both tests at 38 °C / 79 °C and 40 °C / 80

°C and this way facilitates all the ASTM/DIN

standardised procedures; water tanks are equipped with

control heating unit, so no preheating is necessary; the

machine parts are resistant to brine corrosion; spacious

and easy to clean water tank; separate drive for pump

and bearing makes the belt as in older design (Fig. 10)

unnecessary; magnetic bearing drive for easy

disassembly and removal; volume flow setting by a

precise manual control valve.

For rating of the water washout test results the below

Table 3 is applicable [16].
