The Ball Screw is a high-efficiency feed screw with the ball making a rolling motion between the screw axis and the nut. Compared with a conventional sliding screw, this product has drive torque of one-third or less, making it most suitable for saving drive motor power.
If lubricating ball screw with grease it is recommended that a way cover or bellow is installed to protect from debris Also if lubricating with grease, it is not recommended to completely fill the ball nut cavity and should not exceed more than 65% full, as this can exert pressure on the wipers and ball returns.
Grease is more commonly used for ball screw lubrication because it doesn’t entail complicated delivery methods, and it requires less frequent re-lubrication intervals. But despite the simplicity of using grease, in many applications, oil lubrication is the better choice for ball screw assemblies.
A greaseing amount of 40 to 50% of the bearing internal space volume is recommended for a ball screw support bearing (open type). For information about internal space volume of bearings and calculation formula for grease amount, see Table 3. In order to secure the outer ring of a bearing in the axial

Standard ball screw bearings typically require regrinding of end caps to achieve proper fit. With extremely tight width tolerances and the new marking of the individual width set, Timken bearings virtually eliminate the need for regrinding. This reduces assembly costs and machine downtime when servicing ball screws.

The right oil or grease lubrication for ball screw assemblies reduces unscheduled downtime for repair by ensuring that the assemblies deliver their expected service life. The necessary parameters to consider when you select or design a ball screw assembly are operating load, speed, accuracy ...
The noise of grease lubrication is relatively low, and when the working environment temperature is low, low viscosity oil is used. High working oils use high viscosity oils. When the linear bearing is in working condition, the impact force is more difficult to measure.
