A. Construction Rear Housing Stopper Carriage-Nut Grease Nipple Ballscrew Upper Seal End Cap End Seal U Rail Front Housing B. Characteristics KM series consist of linear guideway unit and ballscrew unit. For saving space, PMI combine the carriage of linear guideway and nut of ballscrew to a integral Carriage-Nut. The carriagenut cooperate with the U rail designed for high rigidity to achieve the high rigidity and high accuracy in the minimal space, especially to saving time of installation. Moreover, the design of two rows with Gothic-arch groove and contact angle of 45°can bear four...

Saving Space Combine the carriage of linear guideway and nut of ballscrew to a carriage-nut, KM series can achieve the best use of space. Unit : mm MONO STAGE High Rigidity Base on the optimal analysis of FEM for the shape of U rail, it has the balance between light weight and high ridigity. Y High Accuracy Note* IXGeometrical moment of inertia around X axis IYGeometrical moment of inertia around Y axis The design of two rows with Gothic-arch groove and stable manufacturing technology can control the variation by load at the minimum. It can provide the smooth feed with high accuracy. C5

E. Load Ratings The load ratings of KM series are divided to linear guideway and ballscrew, the load ratings of each part are shown below. Linear Guideway Basic dynamic load rating C (kN) Basic static load rating C0 (kN) Basic dynamic load rating Ca (kN) Basic static load rating C0a (kN) Ball Thread center to Ballscrew Lead minor center diameter (mm) diameter High, High, diameter (mm) Normal Normal (mm) Precision Precision C、D (mm) N N H、P H、P

F. Static Permissible Moments MONO STAGE Unit : N-m Static Permissible Moments Model Note*: The static permissible moments of B and D type are base on two carnage nuts used in closed contact with each other.

KM series is classified into normal grade (N), high (H) and precision grade (P), the standards are shown below.

The calculation of nominal life of each component is shown below. The nominal life is defined as the total running distance that 90% of identical linear guideways or ballscrew in a group, when they are applied under the same conditions, can work without developing flaking.
