Description
B 1.8807 Swing clamps without swing stroke

In this version without axial swing stroke, the clamping arm swivels in one plane and does not make any axial movement when swivelled. 

Special features
• Reinforced swing mechanism
• Connections for pipe threads and drilled channels
 • Radial anti-rotation device in the clamping stroke
 • Indexing of clamping arm for repeatable alignment

Reinforced swing mechanism
The reinforced swing mechanism ensures that the angle position of the clamping arm remains the same even if a slight collision with the workpiece during loading and unloading or during clamping occurs.

Radial anti-rotation device in the clamping stroke
With swivelling clamping devices, workpieces can also be machined overhead. In the event of a sudden drop in clamping pressure, the radial anti-rotation device prevents the clamping arm from swivelling back. The workpiece is then no longer clamped. However, a sensible arrangement of several swing clamps and workpiece positioning aids can prevent the workpiece from falling out of the fixture (see also the note in the operating manual).

Advantages
● Compact design partially recessible
● Compact design
● Extremely short clamping and unclamping times
● Swinging in into narrow recesses
● Wiper with metal swarf protection

Versions
• 3 sizes
• Clamping arm seat with cone 1: 10, pendulum eye or fork head
• 2 clamping strokes per size
• Clockwise, counterclockwise or non-swivelling swing motion 
• Swing angle 0°, 15° to 75° and 90°
• Angle of clamping position selectable for pendulum eye or fork head

Seals
NBR = nitrile butadiene rubber

Double clamping arm
This allows space-saving clamping of workpieces in multiple clamping fixtures. 
Piston rods with pendulum eyes and fork heads are available so that optimally fitting double clamping arms can be attached. 
For a newly designed double clamping arm, the moment of inertia must be determined to 
calculate the admissible flow rate using the formula on page 9 of the catalogue sheet.
