Tensioner Devices
Guide roller suspensions with tensioners SE and
pre-tensioning devices VS
For the accurate definition of the required pre-tension and
limitation of the roller travel we do recommend the use of
our pre-tensioning clamp VS allowing angle adjustments
from 0 – 15° (for all SE-sizes available).
DAT (Double Arm Tensioner)
For the transfer of very high tension-forces we do recom-
mend to use double arm tensioners, avoiding any misalign-
ment or fault of parallelism between tensioner housing and
inner square-core-generating belt eating angular off-set of
the tensioning pulley.
