Ball screw drives KGT
5.6 Oil-mist lubrication
In the case of central lubrication with oil
mist, note that only ball screw nuts with-
out wipers may be used.
5.7 Oil lubrication
The oil supply should not exceed the vol-
ume lost via the wipers; otherwise use
recirculating-oil lubrication.
Oil types: Viscosity 25 to 100 mm

100°C.
6. Operating temperature
The permissible operating temperature
range for ball screw drives is between
–30°C and +80°C, up to 110°C for brief
periods. A precondition for this is correct
lubrication.
The torque may increase by a factor of up
to 10 at temperatures below –20°C.
