OKS 425 is a synthetic grease for long-term lubrication of machine elements.
Areas of application
For the long time- or for lifetime- lubrication of fast running roller and plain bearings as well as linear guides, threaded and ball screw spindles, small gears and similar components, exposed to high pressures and higher temperatures
Advantages and benefits
Good adhesive and good media resistant
Good low-temperature behaviour, stress absorbing ability and smooth run at high speeds
Good plastic compatibility
The low start and running moment, especially at low temperatures, enables a high efficiency
The good wear protection increases the life time of the part and makes sure a reliable function
Operating temperature: -50 °C → +130 °C
NLGI grade: 2
DN factor (dm x n): 1,000,000 mm/min
Base oil viscosity (40 °C): 30 mm²/s
Four-ball test rig (welding load): 3,400 N
For best results clean the lubrication point with OKS 2610/OKS 2611 Universal Cleaner. Remove the corrosion protection media before initial filling. Fill the bearings in a way that all the functional surfaces are lubricated sufficiently. Slow moving bearings (DN-value 400,000) should be filled to 1/4, normal moving bearings to 1/3 of the free inner housing space. Observe the instructions of the bearing or machine manufacturer. Relubrication with a grease gun through the grease nipples or with an automatic lubrication system. Relubrication intervals and amount to be defined acc. to the service conditions.
