Regreasing with grease nipples - while the machine is
running.
The table is prepared for horizontally mounted
machines. Lubrication intervals for vertical machines
are half of the above values.
The grease amount in the table given is used if small
quantities of fresh grease are replaced at regular
intervals as above.
As an alternative, when the machine is fitted with
grease escape valves, fresh grease may be pressed
into the bearings until the old grease is totally
replaced.
The table values are based on 80° C bearing
temperature. The values should be halved for every
15° C increase in bearing temperature.
If the maximum bearing temperature is 70° C, the table
values may be doubled.
The maximum operating temperature of the
grease and bearings must not be exceeded.

Higher speed operation, e.g. frequency converter
applications, or slower speed with heavy load will
require shortened lubrication intervals.
Typically a doubling of speed will require a reduction of
lubrication intervals to approx. 40% of values tabulated
above.
Suitability of bearings for high speed operation must
also be checked.
Lubricants:
When regreasing, use only special ball bearing grease
with the following properties:
good quality lithium base or lithium complex
grease
base oil viscosity 100-140 cST at 40° C
consistency NLGI grade 2 or 3
temperature range -30° C - +120° C, continuously.
Greases with the correct properties are available from
all the major lubricant manufacturers.
If the make of grease is changed and compatibility is
uncertain, lubricate several times at short intervals in
order to displace the old grease.
Highly loaded and/or slowly rotating bearings require
EPgrease.
If lubrication intervals are short due to bearing
temperatures of 80° C or above, use high temperature
greases which normally permit approximately 15 K
higher bearing temperatures.
If the ambient temperature is below -25° C consult the
manufacturer regarding the possible use of low
temperature grease.
NOTE
For high speed machines
machines), check that the fn factor of the grease is
sufficiently high.
fn = Dm x n
Dm = average bearing diameter (mm)
n = rotational speed (r/min)
Many greases can cause skin irritation and eye
inflammation.
Follow all safety precautions specified by the
manufacturer.
12.6.5 Spare parts
When ordering spare parts, the full type designation
and product code as stated on the rating plate must be
specified.
If the machine is stamped with a serial manufacturing
number, this should also be given.

12.6.6 Noise levels

Smaller machines have a sound pressure level which
does not exceed 70 dB(A).
The following table indicates the sound pressure level
of all motor types of the frame sizes 56 - 355, 2 / 4 / 6 /
8 pole.
