Mode of Operation LinClamp S / SK
Beispiel:
NSK - Rail Star - Rail
LinClamp S / SK released:
The chamber between the two spring-steel
diaphragms is filled with compressed air. This
causes the spring plates to deform elastically and
contract horizontally. The clamping body expands
across the linear rail, and the carriage is released.

Mode of Operation
LinClamp S / SK
The air in the chamber between the two
diaphragms is set free, and they return to their
parallel position. The clamping expands at this
point and contracts across the brake blocks,
thereby clamping the rail.

Basic Design
LinClamp S / SK
• Operating principle :
To release the clamping action, the chamber between
the two spring diaphragms is filled with compressed
air. The diaphragms deflect outwards, allowing the
clamping body to return to its original relaxed position.
The brake blocks lift off the rail.
When the chamber is not inflated, the diaphragms
move back pushing apart the upper clamp body.
With the horizontal strut acting as fulcrum point, the
brake blocks are forced against the linear rail, thus
clamping the carriage.
Operating pressure: 5.5 – 6 bar. Other operating
pressures can be offered on request.
• Safety:
The clamping action is initiated on loss of power .
• Reaction times:
Short, due to the pneumatic action.
• Costs:
Low, due to the simple construction and the
pneumatic connection technique.
• Advantages:
- Minimal number of parts in the assembly.
- Can be used with all commonly available rails
- Large brake block surface area provides a long life.

**Holding forces are valid for roller guide ways (INA, STAR) on dry rail, other conditions and rail types upon request. Consider only about 60% of listed holding
forces for greasy rails depending on type of grease used. Special clamp pads with 100% holding forces (not for braking) are available for greasy rails. Clamp is
released at an operating pressure of 5.5 – 6 bar, other operating pressures available on request

Function:
LinClamp SA Active
Rail clamping
To activate the clamping action, the chamber under
the spring diaphragm is filled with compressed air.
The spring sheet is pushed upwards and stretched.
With the horizontal strut acting as fulcrum point, the
brake blocks are forced against the linear rail, thus
clamping the carriage.
When the chamber is not inflated, the diaphragm
moves back into the bended position and the upper
clamp body goes back in its original relaxed position.
The brake blocks lift off the rail.
Operating pressure: 4 – 6 bar.
Costs:
Low, due to the simple construction and the
pneumatic connection technique.
Advantage:
- can be used for nearly all on the market available
rail sizes
- Large braking and clamping bracket surface, long
lasting, durable, clamping and braking possible
- compact design length only 40 mm
- Fast and nearly reaction-free clamping
- Clean and easy to use with pneumatic connection
-Applications:
- Automation, Robotics, Woodworking

Tests from the PTW confirm:

Rail Version
Linclamp S rail clamps achieve verifiable proved
outstanding clamping and braking results, both on
dry, greased and oiled guide rails.
Due to their innovative brake linings of sintered
copper graphite the values remain high, even after
500 braking processes.
The PTW used a 5/3 way valve and showed in
reaction times of 0.02 seconds and braking times of
0.06 seconds.
Linclamp S achieved braking forces of over 8,000
N. During the tests we did not detect any damage
on the rail surfaces. The forces were almost
constant during the testing cycles. Further
permanent tests are ongoing.
All test data are based on standard Linclamp S45
elements with sintered copper graphite on a STAR
rail.
