Anti-Cage Creep Technology

Anti-Cage Creep (ACC) technology reduces cage creep in linear guides down to zero. Even with high accelerations up to 15G, it has been proven to be the most compact and robust solution available in the market.

The problem: cage creep

Cage creep can occur in non-recirculating linear guides applications where vibrations, improper mounting, very high acceleration (and de-acceleration), inadequate tolerances on the mounting surfaces, uneven preloading or moment loading are present. 

As the cage creeps out of its original position, increased friction, reduced travel length and premature wear of the linear guides occur. This results in a shorter lifetime and can result in premature failures. 


Our solution: anti-cage creep (ACC)

The engineers of PM have further enhanced the ACC technology, making it suitable for high-tech and extremely dynamic applications. ACC is integrated into a crossed roller guide with either a glued rack or with electro-chemical machining (ECM) directly into the rail.

For decades, the ACC solution of PM has proven its superior ability to prevent cage creep when applied in the most demanding applications and operating in the most challenging conditions. The ACC technology is integrated into the design of the linear guide without influencing the external boundary or mounting dimensions. This allows for drop-in replacement of guides in under-performing applications with the ACC solution without additional machining of table parts.

Friction force

The ACC solution is the result of an extremely careful design and manufacturing process. The graph illustrates the resulting fact that the force to be applied to overcome friction remains virtually unchanged. 

Operating temperature

Linear guides with ACC are capable of operating in temperatures up to +80 °C. This gives ACC a significant advantage over similar systems using plastic components.
