Maintenance
End Cap and Lubricating Systems are essential in order to protect and lubricate
the Bearing Units. These should be fitted back in place only when the guide
carriage has been mounted on the Shafts. Otherwise, it is important to ensure
the movable wipers are pressed back when sliding the guide carriage onto the
Shaft, to ensure they are not bent.
Wipers located in the internal recesses of the end-face End Cap and Lubricating
Systems are also designed to take up the lubricant. They are pressed against
the guiding Shaft by a spring. These wipers are supplied pre-charged with lubri-
cant and can be topped up with lubricant as required via the hole in the cap.
In the event of considerable soiling, you may need to replace the wipers.
Ball Screw Units KGT are virtually maintenance-free. The initial greasing has to
be renewed after around 400 to 500 operating hours. The following intervals
vary according to operating conditions. As the amount of grease applied when
renewing lubrication is lower than the initial greasing, maintenance intervals
subsequently get shorter (approx. every 200 to 300 operating hours). A spray-
able grease with a mineral-oil base such as GLEITMO 815 (Fuchs Lubritech) is
particularly suitable. Lubrication is renewed via the lip seals. Apply a thin, even
coating of grease directly to the screw.
Suitable for use in dry conditions and over the temperature range -20°C to
+70°C.
If operating conditions are unusual, e.g. special type of installation, dust, short
stroke, influence of solvents etc., the lubrication intervals must be adapted
accordingly.
This information does not discharge the user from the obligation to carry out his
own assessments and checks.
It is important to bear in mind that our products are subject to a natural process
of wear and ageing.
The rollers of the guide are maintenance-free. The spring-loaded end cap and
lubricating felts can be topped up with lubricant as required via a hole.
Recommended re-oiling period: Every 6 months or every 2500 km. The felt
pieces are supplied in ready-oiled condition.
Synthetic lubrication oil ISO VG 460, e.g. item Track Oil for Linear Guides
(0.0.612.75).
Add the following quantity to each maintenance hole at the end of each mainte-
nance interval: 2 ml
Grease containing solid particles (e.g. graphite and MoS2 additives) must not
be used.
Oil Can for Linear Guides (one actuation delivers approx. 1 ml of oil).
To ensure adequate lubrication, the carriage must cover a minimum travel
distance. Minimum stroke length [mm]: 320 mm
Ideal operating conditions:
Ambient temperature: 10 °C ... 40 °C
Load:
<5%
The drawings and formulae can be used to help calculate the relevant end
positions when installing the Slide Stops in relation to travel. You can use both
sides of the support profile to install Slide Stop LRE 8.
In the case of Linear Units LRE with a rack drive, Slide Stop LRE 8 can only be
installed on the side opposite the Motor.
Roll the T-Slot Nuts into the groove under the shaft on the side where you are
going to install the Stop.
Use two screws (M6) to attach the basic unit, but do not tighten them at this
stage. When installing the basic unit, make sure the threads are facing toward
the Reverse Unit.
Next, slide the basic unit along the groove until the outside edge facing the
Reverse Unit is in line with the mark you made earlier and then tighten with the
appropriate torque.
Finally, use two M6 screws to attach the Slide Stop to the basic unit and tighten
with the appropriate torque – M = 9 Nm.
