1. PRODUCT DESCRIPTION
1.1 Introduction
1.1.1. Utilization
The linear unit LH 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 linear unit LH, 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. SAFETY REGULATIONS
2.1 In general
®
See chapters 1.1.1
1.1.2
1.1.3
2.2 Specifically
Do not make any changes or modifications to the unit (voids warranty).
3. CONSTRUCTION AND FUNCTION
The stroke adjustment can be made infinitely variable with the end screws AS
12/60 (Pos.101) in order to check the occurred movement, the end screws can be
fitted with our sensing elements (see Meto-Fer
4
®
Electronics catalog).
OPERATING MANUAL (LH)
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 one-way restrictors DV-R1/8" (see sheet
5.021). Unused air connections must be covered with the R1/8 caps.
4.2 Stroke Adjustment
- Loosen screw (Pos.102 and 110) and plate (Pos.9), move to the needed
position.
- Tighten screw, make sure piston rod and shaft (Pos.6) are parallel.
- Loosen nut on stop screw.
- Adjust the needed stroke on AS 12/60 (Pos.115).
- Tighten security nut on the stop 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
5
The linear unit does not require any special maintenance procedure. Never use
any type of solvents in order to clean the unit.
OPERATING MANUAL (LH)
5.2 Air Supply
The 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 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 interrupted. 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 end plate (Pos.9) by loosening the screws (Pos. 102, 110).
- Loosen the set screws (Pos.106) and remove plate (Pos.8).
- Extract the housings (Pos.1).
- Extract the piston rod and guide shaft (Pos. 5 and 6).
- Extract the cylinder pipe (Pos.4).
- Clean the parts.
6
- Replace the seals.
- Check all parts for wear and grease cylinder pipe, guide shaft, piston rod
(see Chapter 7.2).
OPERATING MANUAL (LH)
- The parts are then assembled in reverse order as described above.
6.4 Replacing the linear ball bushings
Disassembly same as Chapter 6.3.
- Extract linear ball bushings.
- When assembling the ball bushings, make sure the seal rings lie on the
outside of the housing.
The parts are then assembled in reverse order as described in Chapter 6.3.
