Kop-Flex Industrial Coupling Product Catalog - Form 8887E

Fast’s ® Brake Wheel Couplings
Types DMW, DEW & DRW
FAST'S ® Brake Wheel couplings permit a
choice of applying the braking effort directly
to the load or to the driving motor. The brake
wheel can be mounted on that coupling in
the drive system which is closest to the
load. Standardized dimensions, less WR2,
versatility of mounting positions, replaceable
brake wheels, reduced maintenance, and
lower replacement costs are features
of these units. Types DE and DM flexhalves
with a bolted-on end ring facilitate
installation and maintenance.
All Brake Wheel couplings can be used
without modification for vertical operation.
Wheels are machined from Grade 80-60-.03
ductile iron to conform to ASTM-A-339-55
and most mill crane specifications. Grade
GA Meehanite** is a substitute material.
A brake wheel position is measured from
the centerline of the wheel face to the end
of the driving shaft.
