The ball screw drive is an assembly that converts rotary motion to linear motion (or vice versa). It consists of a ball screw and a ball nut packaged as an assembly with recirculating balls. The interface between the ball screw and the nut is made by balls which roll in matching ball forms. With rolling elements, the ball screw drive has a low friction coefficient (typically up to 98%). The forces transmitted are distributed over a large number of balls, giving a low relative load per ball comparatively.
Ball and Lead screws must be lubricated to operate properly and achieve the rated life.
The TriGEL grease can be applied directly tothe screw threads near the root of the ball track.
Screws may require lubrication frequently depending on both environmental and operating conditions. If the lubricant appears to be dispersed before this point or has become dry or crusted, the maintenance interval should be more frequent
Before adding additional grease, wipe the screw clean, removing the old grease and any particulate contamination seen on the screw
