These couplings are designed for use on
general applications. The units are offered
as standard, but can also be modified to
incorporate options including torque
limitation, torque measurement, etc.
The arrangement maybe adapted to
permit connection to machines by any
conventional form.
The following section outlines data for
the standard disc couplings for general
purpose use. The following points should
be noted in relation to these products:
• DS units will accept angular & axial
misalignment only. If radial
misalignment is expected, D or DJ units
should be considered.
• DJ units consist of factory assembled
transmission units. Installation involves
fitting this transmission unit between
the hubs and tightening the
attachment screws only. This leads to
easier and more rapid installation.
• Variations in DBSE are available to
suit customer’s requirements. For long
spans, fabricated steel spacers are
available (designation DJCT). The
composite shaft, DJCFT, units may be
considered.
• Maximum speeds are shown for
standard materials. When higher
speeds are required, consideration
should be given to the high
performance, HS, range of units.
• Momentary overloads of 2x and
shock loads of 3.7x the stated rating
are accepted by these units.
• Larger rated units are available by
special design. Please contact our staff
for more information.
