This ball screw grease is a precision‑grade lubricating grease using high‑performance synthetic base oil and dedicated thickener with compound functional additives. It features excellent shear stability and low‑friction characteristics under circulating‑ball movement. The grease resists oil separation under continuous cyclic operation, minimizes micro‑abrasion on screw raceways, and provides long‑term lubricating protection for ball screw drive assemblies on CNC machine tools.

Product Detail

Product DetailsBall Screw Grease Synthetic Oil, for Precision Drive CNC Machine Tool Ball ScrewThis ball screw grease is compounded with premium synthetic base fluid, refined soap‑based thickener and integrated additive package including anti‑wear, friction modifier, anti‑oxidant and anti‑rust components. The formulation is tailored for the unique kinematic condition of recirculating ball assemblies inside ball screw nuts. It maintains suitable paste consistency, avoiding excessive softening that leads to centrifugal oil throw‑off during high‑speed screw rotation, while not becoming too stiff to restrict ball circulation.

When applied to screw thread raceways, ball nut internal grooves and circulating ball return channels, the grease establishes a continuous boundary lubricating film between steel balls and hardened raceway surfaces. During high‑speed forward‑reverse rotation of CNC feed axes, it reduces rolling‑sliding mixed friction. Stable friction performance helps the servo‑drive system achieve accurate positioning and repetitive positioning, lowering positioning error induced by fluctuating frictional resistance.

Under sustained cyclic mechanical shearing from circulating steel balls, the grease structural network maintains good integrity and effectively inhibits oil bleeding. The antioxidant additives slow thermal ageing triggered by frictional heat generated during frequent acceleration‑deceleration cycles of machine‑tool feed drives. Anti‑rust ingredients offer protection for precision‑ground screw surfaces against trace ambient moisture inside the machining workshop, preventing tiny rust spots that would scratch the raceway.

It is suitable for pre‑lubrication during ball‑screw component assembly and periodic maintenance re‑greasing for vertical and horizontal feed‑drive ball screws on CNC lathes, machining centers and milling machines. A thin uniform coating is required. Excessive grease filling inside the ball nut cavity will produce viscous churning resistance, generate extra heat and deteriorate the dynamic response of precision feed axes.

Do not mix this synthetic ball screw grease with polyurea, fluorinated PFPE grease or heavy‑duty sulfonate greases. Incompatible blending will damage the grease network, increase friction coefficient and impair precision‑drive performance. Store in tightly sealed original containers inside cool, dry indoor warehouse. Avoid prolonged high‑temperature storage to retain original shear‑stable consistency for CNC machine tool precision ball screw drive lubrication.
