Description:
Put the grease sample into the ball bearings, and then loaded the bearings into bearing holder which has the specified clearance requirements and roll the holder at the speed of 600r/min±30r/min. To spray the water (under the temperature of 38C or 79C) to the bearing holder at the rate of 5mL/s+0.5mL/s and to measure the water resistant ability by the grease volume washed out by the water within 60 min.
Features:
- All-in-one structure, the instrument shell is made of refined steel plate and coated with glaze, very durable.
- The test bearing chamber and shell are in full compliance with the standard method requirements.
- Stainless steel water tank with inlet and out of water pipes, aluminum bearing rooms, copper chrome cycle pump, 1/4 HP motor.
- Stainless steel heater.
- The temperature controller of the instrument is integrated with control and display, and equipped with microprocessor for PID adjustment
- Unique design, you can start the pump circulation system independently without starting the test shaft.
- Fixed speed motor, no need to speed regulation, the speed is 600rpm.
