DPM 6188

DPM 6188 corresponds to Royco 22MS.

ROYCO 22MS is recommended for use in applications where severe operating conditions may include temperatures as high as 450 F and as low as -65 F, low speeds, high loads, extreme pressures on sliding surfaces, splines, ball screws, and anti-friction bearings where the graphite and MOS2 may provide an added measure of protection against seizure in the event of inadequate lubrication due to extreme temperatures or mechanical spread out of the lubricant.

For more information see Royco 22MS
