Corrosion Preventive Test

This test method covers the determination of the corrosion preventive properties of grease using grease-lubricated tapered roller bearings stored under wet conditions.

APPARATUS : Distributes a lubricating grease sample in a roller bearing by running the bearing under light thrust load. Corrosion preventive capability is determined on a pass/fail basis by the presence of rust spots (1mm or larger) on the bearing race after a 60 +3 second run-in period followed by prolonged exposure to water at constant temperature.

Complete with Variable Speed Controller with Electric Motor 1750rpm +50rpm Speed, Run-in stand, Bearing holder assemblies, Plastic test jar, Spindle/thrust loading device, Mechanical grease packer pliers and Test Bearings. Corrosion preventive equipment consists of the control panel with a rocker ON/OFF switch, Variable Speed Controller, Digital RPM meter and a stand with drive motor on base with driving cone hub, thrust, locking device, mechanical grease packer, test bearing etc.

Power supply : 230 +10% Volt AC, 1 Phase, 50 Hz.
