Ball Screw Series

The threaded raceway features an arch curve, ensuring uniform force distribution and stable contact conditions; the lead screw shaft undergoes stabilisation heat treatment to minimise the risk of deformation during long-term operation.

Key Product Advantages
A rolling friction design ensures high transmission efficiency of over 90 per cent, effectively reducing the load on the servo motor and saving energy;
Stable Precision: Available in a range of precision grades including C3, C5 and C7; preloaded models achieve backlash-free transmission and offer excellent repeatability;
Durability and Reliability: The raceway surfaces possess sufficient hardness and excellent wear resistance; under appropriate lubrication conditions, they offer a long service life and outstanding fatigue resistance;
Flexible Compatibility: Featuring a multi-nut design and a variety of lead options, they support various installation configurations including high-speed, low-speed, vertical lifting and horizontal transmission; Custom specific requirements can easily be accommodated for.

Applications
Precision automation equipment. Machine tools such as CNC machining centres, engraving machines and grinding machines etc.
3C automation equipment, lithium-ion battery production fixtures and semiconductor testing platforms utilise high-precision versions to achieve precise positioning;
Logistics conveyor systems, packaging machinery and injection moulding auxiliary equipment employ standard models for reciprocating motion;
Medical automation equipment, optical experimental platforms and small servo modules primarily utilise low-noise, precision models.

Heavy-duty lifting platforms and heavy-duty gantry equipment can be fitted with heavy-duty ball screws featuring large lead.
As a core component of linear motion systems, CRK ball screws can be supplied as part of a complete system alongside our own linear guides, providing integrated motion solutions for high-end equipment.
