Shaft extension with standard dimensions, without feather
keyway
For motor series 1LE1, 1LE5, 1MB1, 1MB5, and 1PC1, the standard
shaft extension can be ordered with standard dimensions
without a feather keyway. The key convention does not have to
be stamped onto the rating plate for balancing.
Order code L04
Standard shaft made of stainless steel
A standard shaft made of stainless steel can be ordered for the
1LE1, 1LE5, 1MB1, 1MB5, and 1PC1 motor series (e.g. 1.4021).
This is only possible for shaft extensions of standard dimensions.
Order code L06
Special non-rusting materials are only available on request.
Non-standard cylindrical shaft extension
The non-standard cylindrical shaft extension can be used on the
drive end (DE) (with plain text according to table). The feather
keys are supplied in every case.
Order code Y58
For order code Y58 non-standard cylindrical shaft extension (DE):
• Dimension D: less than or equal to the inner diameter of the
roller bearing, tolerance band less than tolerance band acc.
to EN 50347.
• Dimension E: less than or equal to 2 × length E (standard) of
the shaft extension.
See the table below "Admissible changes to the shaft extension DE"
and the dimension tables in the relevant sections of the catalog.

Standard, cylindrical shaft extension NDE acc. to EN 50347
(second shaft extension)
Order code L05 (on request)
For a coupling output, the standard, cylindrical shaft extension
can transmit the full rated power.
Please also inquire about the transmitted power and admissible
cantilever force if belt pulleys, chains or gear pinions are used
on the standard, cylindrical shaft extension.
A standard, cylindrical shaft extension (second shaft extension)
NDE is not available if a rotary pulse encoder and/or a separately
driven fan has been mounted onto the motor. Please inquire
for mounted brakes.
Dimensions and tolerances for keyways and keys are designed
to EN 50347. The motors are always supplied with a key inserted
in the shaft.
If the second shaft extension has non-standard dimensions, this
must be ordered with order code Y59 non-standard shaft dimensions
NDE.
For the order code Y59 (with plain text specifications according
to the table).
• Dimension D: less than or equal to fan hub inner diameter, for
frame size 160 tolerance band is less than tolerance band to
EN 50347
• Dimension E: less than or equal to 2 × length E (standard) of
the shaft extension

NDE" and the dimension tables in the relevant sections of the

Non-standard, cylindrical shaft extensions up to the specified
lengths and diameters can be supplied for the motor series
listed in the tables "Admissible changes to the shaft extension
DE (Y58)" and "Admissible changes to the shaft extension NDE
(Y59)". All other dimensions are available on request.
It is the responsibility of the customer to ensure that the admissible
cantilever forces are reduced in accordance with the nonstandard
shaft extension.
1) At maximum admissible diameter, a step increase in shaft diameter is not
possible.
