- The LCS-125T7 and LCS-155T7 are semi-standard products (delivery time confirmed).
- The allowable radial direction displacement indicates the case the eccentricity and tilt angle are zero.
- Please insert the shaft up to the marking line J correctly.
- The moment of inertia and mass are shown for the maximum shaft hole diameter.
- The recommended shaft tolerance is h6. (For a shaft diameter of 35 mm, it corresponds to a tolerance of +0.010).
- The maximum rotational speed does not consider dynamic balance.
