Sealing of the motor shaft
Table 3- 10 Motor shaft sealing
IP64 IP65 IP67
Labyrinth seal
It is not permissible that there is
any moisture in the area around
the shaft and the flange.
Note:
For IP 64 degree of protection it is
not permissible that liquid collects
in the flange. Shaft outlet is not
dust-tight
Radial shaft sealing ring without annular
spring
Shaft outlet seal to protect against
spray water and cooling-lubricating
medium. It is permissible that the radial
shaft sealing ring runs dry. Lifetime
approx. 25000 h (nominal value).
For IP65 degree of protection it is not
permissible that liquid collects in the
flange.
Radial shaft sealing ring
For gearbox mounting (for gearboxes that
are not sealed) to seal against oil.
The sealing lip must be adequately cooled
and lubricated by the gearbox oil in order to
guarantee reliable function.
Lifetime approx. 10000 h (nominal value).
If a radial shaft sealing ring runs dry, then
this has a strong negative impact on the
functionality and the lifetime.
3.5 Bearing version
The 1FT7 motors are equipped with greased-for-life deep-groove ball bearings. The location
bearing is at the DE.
