10.4.1.3 - Roller bearings housings with grease nipples
The bearings are lubricated in the factory.
The instructions required for bearing housing maintenance are
shown on the machine nameplate.
For motors of frame size equal to or greater than 200, the
bearing housings are fitted with bearings lubricated by
Técalémit-Hydraulic M8 x 125 type grease nipples.
The frequency of lubrication and quantity and
quality of grease are indicated on the nameplates.
Refer to these to ensure correct greasing of the bearings.
The interval between greasing operations must
never, under any circumstances, exceed 2 years,
even in the event of prolonged storage or downtime.
10.5 - Bearing housing maintenance
10.5.1 - Checking bearings
As soon as you detect any of the following on the motor:
- abnormal noise or vibration,
- abnormal heating at the bearing although it is properly
greased,
the condition of the bearings must be checked.
Damaged bearings must be replaced as soon as possible to
prevent worse damage to the motor and the equipment being
driven.
When one bearing needs to be replaced,
the other bearing
must also be replaced.
The free bearing must allow the rotor shaft to expand (check its
identification during dismantling).
10.5.2 - Refurbishing bearing housings
Roller bearing housings without grease nipples
Remove the motor (see § 10.2.1); remove the old grease (if the
bearings are not of the sealed type) and clean the bearings and
accessories using degreaser.
Apply new grease: the bearing housing must be filled to 50%
of the free volume with new grease.
Roller bearings housings with grease nipples
Always start by cleaning old grease from the channel
When the plated grease type is used, remove the covers and
clean the grease nipple heads.
When a grease other than the plated grease type is used, the
motor must be dismantled and bearings and accessories
cleaned using degreaser (carefully clean the grease inlet and
discharge channels) to remove all old grease before greasing
once more.
To ensure correct lubrication the internal free volumes of caps,
flanges must be filled and 30% of the free volume of bearings.
Then rotate the motor to distribute the grease.
Warning!
To great a quantity of grease can cause excessive heating of
the bearing (statistically the number of bearings damaged by
excess grease is greater than the number of bearings damaged
by lack of greasing).
Do not mix different types of grease (even if the soap
bases are the same). Non-miscible lubricants can
damage the bearings.
Important! Please note
The new grease must have been recently manufactured, and
must have equivalent performance levels and must not contain
any impurities (dust, water or other impurities).
Bearings may be electrically insulated. Their type of
marked on the nameplate.
