Water Washout Tester As per ASTM D1264 The water washout apparatus is suitable for testing water washout characteristics of grease as per ASTM D1264. A sample of the lubricating grease under evaluation is tested in a bearing rotating under specific speed by spraying heated water and the loss of grease is determined. A tank is provided to hold about 750 ml of water with heating arrangement for heating the water to up to temperature 80°C. The equipment is provided with test bearing housing assembly as specified in the test method. The digital temperature controller with sensor is also provided for accurate indication of the temperature inside the equipment. The unit is provided with a ball bearing (ASTM 204) as specified in the test method. Circulating pump provided with a supply pressure and a return suction line, regulating valves, a splash nozzle and accessory.The pump is capable of delivering 300 ml/min heated water via 1mm capillary. The water containing washed out grease is collected in the tank, filtered & recycled during the test. Provision is made for fine adjustable of water flow through a bypass to allow the preheated water to circulate without passing through the jet or impinge on bearing housing. Features The bearing rotational speed is 600 ± 30 rpm. Supplied with test bearings – 2 Nos. Drain valve to remove the tested water. Provided with necessary tools and fixtures for assembling of bearing housing. Power supply : 120 V / 230 AC, Single Phase, 50 / 60 Hz

Drop Point of Grease Wide High Temperature Range The ASTM D2265 dropping point tester is used for high temperature grease testing than the ASTM D566 method. This equipment uses a different heating procedure as compared with ASTM D566. The test cell is inserted in an aluminum block oven maintained at a constant temperature that is higher than the expected dropping point of the sample. The sample temperature then rises to the dropping point without operator control. The equipment can be offered with Two / Four / Six sample testing capability. Maximum Temperature is 400 °C.

Leakage Tendencies of Wheel Bearing Grease tester, As per ASTM D 1263 This test method for Grease testing determines the tendency of grease to separate oil or grease under prescribed laboratory operating conditions. The test is performed at a high temperature in a modified automotive spindle-hub assembly rotated at the speed of 660 rpm. Any leakage of oil or grease during the test period is collected and weighed. The equipment is made of stainless steel oven with forced air circulation.The temperature is controlled by PID Controller. The accessories included are Wheel bearing spindle, front wheel hub, driving belt pulley, grease leakage collector, front roller bearing, rear roller bearing.
