Shock
The shock load of the motors is indicated by providing the maximum permitted
acceleration in non-stationary use, such as during transport.
Damage to functions is prevented by maintaining the limit values specified.
Based on DIN EN 60721-3-3 and DIN EN 60068-2-6, the following values result

Output Shaft and Shaft Sealing Ring
9.9.1
Plain Shaft
The standard design recommended for MKE motors provides a non-positive
friction-locked shaft-hub connection without play and excellent running smooth‐
ness. Use clamping sets, clamping sleeves or clamping elements to couple the
machine elements to be driven.
9.9.2
Output Shaft with Key
The optional key according to DIN 6885, Sheet 1, version 08-1968, permits
keyed transmission of torques with constant direction, with low requirements
for the shaft-hub connection.
