1. PRODUCT DESCRIPTION
1.1 Introduction
1.1.1. Utilization
The vertical unit VE 22/52/82 (Type A, B) is able to execute linear movements
in any position. This linear movement can be adjusted in its working area
(stroke).
1.1.2. Safety Precautions
Before starting to operate the vertical unit VE 22/52/82 (Type A, B), it is
necessary to check that no body parts are within the working range of the element.
In such a case the unit must not be operated.
The maximum supply pressure of 8 bar must not be surpassed.
1.1.3. Danger Area
Any body parts are to be kept out of the working area (stroke area) of the unit in
order to avoid mangling.

2.2 Specifically
Under no circumstances are any changes or modifications to be made on the unit.
3. CONSTRUCTION AND FUNCTION
The stroke adjustment can be made infinitely variable with the end screw AS
08/40 (Pos.101) in order to check the occurred movement, the end screws can be
fitted with our sensing elements (see Meto-Fer
4. INITIAL OPERATION
4.1 Compressed Air
Remove the safety caps from the air connections. In order to regulate the velocity
of the movement, we recommend our flow controls DV-M5 (see sheet 5.021).
Unused air connections must be covered with the M5 caps.
®
Electronics catalog).
4.2 Stroke Adjustment
- loosen security nut on the end screw
- adjust the required stroke with the end screw (Pos.101)
- tighten security nut on the end screw
4.3 Cushion Adjustment
The basic adjustment of the cushions has to be optimized by the user upon
his special requirements.
The position of the cushions can be seen on the construction drawing.
The brake resistance can be changed by adjusting the length of the brake path.
When using oil and elastomer cushions, it must be checked that the end stop is
not made by the cushions. The cushions should show a remainder stroke of
0.039” (1mm).

5. MAINTENANCE
5.1 Introduction
The mini linear unit does not require any special maintenance procedure. Never
use any type of solvents in order to clean the unit.
5.2 Air Supply
The mini linear unit is equipped with oil-free seals and can be operated with dry
and non-oiled compressed air. If oiled compressed air is used, we recommend:
- Airpress compound SAE 5 (Klueber Order No. 063027)
6. REPAIR
6.1 Introduction
If the unit no longer meets the desired requirements (leakage, wear, etc.) the
defective parts must be replaced.
6.2 Safety Precautions
Before dismounting the unit, it is necessary to check that the compressed air
supply is turned off. It is best to disconnect the compressed air supply from the
unit.
When repair work is done, only the original spare parts and lubrication must be
used.
6.3 Replacing the Seals
- Remove the top end plate (Pos.2) by loosening screws (Pos.216 and 202).
- Remove the bottom end plate (Pos.3) by loosening screws (Pos.202) and
extract by help of press.
- Extract guide rod (Pos.5).
- Remove the clips by the end cylinder caps (Pos.203) and
5
- Extract the two caps (Pos.7) by disassembling the clip (Pos.203).
OPERATING MANUAL (VE)
- Extract the piston rod (Pos.4).
- Clean all parts.
- Replace the seals.
Grease the cylinder, piston rod, guide shaft (see Chapter 7.2).
- The parts are then assembled in reverse order as described above.
6.4 Replacing the linear ball bushings
- Remove the plate (Pos.2). Extract all parts as described in Chapter 6.3.
- Remove the cylinder (Pos.1).
- Remove linear ball bushings (Pos. 211) and replace with new greased
bushings. Please note that the seal rings lie on the outside of the housing.
