New in box AC Servo Motor 2900W 23.8A 200V SGMG-30ASR Industrial Servo Motor

In some cases, water-cooling for the oil is impractical or undesirable and the normal operating oil temperature will be in range of 75-100°C (170-210ºF). Also, in some cases, the bearing size, thrust-load and speed are so high that even with water cooling the normal oil temperature may be as high as 100°C (210ºF). In these cases, it is especially important that proper viscosity, high-grade oil containing an oxidation inhibitor be used. Observe the condition of the oil frequently and change oil when it begins to show signs of deterioration.

Oil-lubricated bearing housings are provided with large settling chambers in which dust, dirt, and sludge collect. Unless the oil has been permitted to oxidize, the draining of the old oil during regular changes will usually provide sufficient flushing action to clean out the reservoir.

Whenever the motor is disassembled for general cleaning and reconditioning, the bearing housing may be washed out with a suitable cleaning solvent. 1,1,1, Trichloroethane may be used, following the same instructions and cautions as shown for cleaning windings. Avoid using any solvent that will soften the paint used on the interior of the oil reservoir. Be sure that the oil-metering hole is clear, and then dry the housing thoroughly before reassembly.
