About Product
Efficient: Direct power transmission by pure cylindrical contact geometry.
Rigid: knee lever with homogeneous pressure distribution all around without edge pressure.
Precise: Accuracy from the one-piece design is transferred to the application.
Self-centering: high coaxiality by means of 360° symmetry.
NMTG Clamping Sleeve is designed to overcome disadvantages of keyed connection or Shrink fit connection. Clamping Sleeves eliminate need of expensive machining operations such as shaft-hub keyways, splines & bolt holes by creating instant Shrink-fit connection & returns to their original condition for easy disassembly when unclamped. The need of Reliability, Dynamic Stress level is increasing. So, NMTG Clamping Sleeve is high quality shaft-hub connection which satisfies modern Engineering Demands.

Introduction
NMTG Clamping Sleeve is designed to overcome disadvantages of keyed connection or Shrink fit connection. Clamping Sleeves eliminate need of expensive machining operations such as shaft-hub keyways, splines & bolt holes by creating instant Shrink-fit connection & returns to their original condition for easy disassembly when unclamped.
The need of Reliability, Dynamic Stress level is increasing. So, NMTG Clamping Sleeve is high quality shaft-hub connection which satisfies modern Engineering Demands.
Function:
NMTG Clamping Sleeves are Cylindrical Symmetric components with a Predetermined Internal & External Grooves. Now, when these Clamping Sleeves will get axially compressed by Clamping Force, Radial Force will generate which create high concentric shrink-fit connection between Shaft, Clamping sleeves & Hub. This Shrink-fit connection will provide backlash free Torque Transmission. When Clamping force removed or relaxed, Clamping Sleeve will retain its original position for easy removal.
Though apparently seems simple but preparing keyway is one of the difficult machining operations:
The cumulative effect of the all above (operational) errors, is really calls for an alternative system-keyless Transmission.
NMTG Keyless Transmission Elements entirely eliminates drawbacks of key transmission and conventional shrink connections and also involved calculations, extremely close machining tolerances - creating problems while fitting & removing parts and during repair work - adjustment, exchanging, etc. It efficiently replaces, key & polygon connections, splined shafts, etc.
