Rimtec couplings' unique taper lock design is ideal for precision,
Rimtec Corporation introduces a series of zero-backlash bellows
and torque-limiting safety couplings designed specifically to meet
the demands of today's highly dynamic digital servo drives, spindles
and tools operating at speeds up to 10,000 rpm. Designed with an outside
conical hub, the high-performance couplings are ideal for precision
machine tool applications.
couplings provide servo-quality stiffness and low inertia for high-production
transfer lines; the ballscrew slides and gearboxes of robots; CNC
machine tools; packaging, textile and printing machines; and other
manufacturing applications with high rotational speeds and high-torque
The unique outside taper lock is self-aligning, which enables the
couplings to be assembled without the concern for misalignment that
is common with inside tapers. The outside conical hubs automatically
quick-release when disassembling, resulting in highly accurate manufacturing
tolerances, improved bearing wear, and dramatically less machine downtime.
Release set screws are also available for the demands of the highest-torque
The lightweight, torsionally rigid stainless steel line of
AK/SB metal bellows couplings accurately compensate for heat,
pressure and elastic deformation that commonly cause axial, radial
and angular misalignment. The line transmits torque from 160 in-lbs
(18 Nm) to 44,400 in-lbs (5,000 Nm) on shaft sizes from 3/8" (9 mm)
to 3.35" (85 mm).
DMK/SB safety couplings are similar to the AK/SB line, except the
inside conical hub and rear flange are one part ... thus reducing
the possibility for misalignment. These couplings are ideal for high-speed
tooling, as the flange on which the gear is mounted can meet run-out
tolerances of up to 0.0008" (0.02 mm). The line transmits torque
from 90 in-lbs (10 Nm) to 14,400 in-lbs (1600 Nm) on shaft sizes from
1/2" (12 mm) to 3.5" (90 mm).
