- LCD-125T7 and LCD-155T7 are semi-standard products (delivery time confirmed).
- The allowable radial direction displacement represents the case the eccentricity and tilt angle are zero.
- The eccentricity and tilt angle act simultaneously. The system restricts the allowable tilt angle. Insert the shaft up to the marking line J correctly.
- The moment of inertia and mass represent the maximum shaft hole diameter.
- The recommended shaft tolerance is h6, corresponding to a tolerance of 0 to 0.010 for a shaft diameter of 35 mm.
- The maximum rotational speed does not account for dynamic balance.
