High Temperature Wheel Bearing Grease Tester

As per ASTM D3527 ,D4290, D4950. The equipment is used for testing of grease for evaluating its life performance by testing at high-temperature. The equipment consists of a modified front wheel hub-spindle-bearings assembly housed in a constant temperature oven and coupled to a ¼ Hp variable-speed drive motor. It Control the test functions automatically and provides continuous digital display of motor torque, rpm, chamber temperature, spindle temperature, time cycle and elapsed time. Test parameters outside of ASTM specifications can be selected by the operator for in-house testing. Automatically terminates test and displays elapsed on-cycle hours when grease deterioration causes drive motor torque to increase to the calibrated end point. A built-in thirty second time delay circuit prevents erroneous test terminations due to momentary surges in motor torque at the beginning of the on-cycle. Insulated constant temperature oven is equipped with a 1200W heater and balanced 1/20 hp circulation fan for efficient heat distribution. Sliding access doors and a movable platform that swings the drive motor out of the way provide easy access to the spindle assembly. Modified steel spindle and hub assembly conforms to all critical 1971 Chevy II dimensions and is fitted with thermocouple, bearing thrust loading device and anodized aluminum grease collector. All controls and monitors are housed in a separate cabinet. Digital controls and displays: Timer : on/off cycle and real time Motor rpm : 0-1725 rpm Motor Torque: current draw Elapsed Time: 9999.9 hr. Maximum Temperature: 177°C Electrical Requirements 220-240V 50Hz, Single Phase, 7A Included Accessories Thermocouples (2) Thermometer holder Bearings (1 set) Grease Packer Assembly Bearing Installation/Removal Tools: Bearing installer, small and large bearing cup removers, bearing cup installer, bearing puller and spindle wrenches (pins)

Grease Testing Equipment

Drop Point of Grease Wide High Temperature Range

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.

Water Spray Off Tester

WATER SPRAY OFF TESTER As per ASTM D 4049 Water spray off tester evaluates the ability of a lubricating grease to adhere to a metal surface when subjected to a direct water spray under controlled conditions. The percentage of grease sprayed off a stainless steel test panel after a specified period is determined by weight. - It Conforms to ASTM D4049 specifications The equipment including spray chamber, delivery system and constant temperature reservoir. It Sprays water at the specified rate and temperature on a test panel coated with sample grease. To test for water spray resistance, fill reservoir with 8L of tap water and set the temperature comtroller at test temperature. Circulate the water through the system to attain temperature equilibrium and insert the coated test panel in the spray chamber. Adjust water spray to 40psi (276kPa) and continue for 5 minutes. Water spray system includes 1.3hp positive displacement pump; spray nozzle with snubber fitting: 0-60psi pressure gauge; bypass valve; shut-off and drain valves; and flexible high pressure water lines. Hinged acrylic spray chamber cover is recessed into the chamber housing to insure watertight operation.
