B-2. MEDIUM AND LOW SPEED AND
SMALL FEED ANGLE
(Feed frequency : N = Up to 300 times/min.)
(Feed angle : θ = Up to 90°;N ×θ= 20,000 max.)
Indexing in this application range is applicable to
many machines. The figure shows an example of use
in the paper feeding section of an automatic stapler.
The reciprocating movement of the eccentric disk is
converted by the Cam Clutch into an intermittent feed
motion, which drives the belt conveyor. Hence,
stapling is timed to the intermittent feeding motion and
load overrun is prevented by a brake. Stapling is done
at an exact pitch. This indexing can be applied
extensively to food and other packaging machines.

B-3. LOW SPEED AND LARGE FEED
ANGLE
(Feed frequency : N = Up to 150 times/min.)
(Feed angle : θ = 90° and up; N ×θ= 50,000 max.)
Segmented gears and rack & pinions are often used
to produce the reciprocal movement to be transmitted
to the Cam Clutch. The figure below gives an
application example of a pouch making machine.
Since the reciprocal movement of the eccentric disk is
accelerated through the rack & pinion assembly, the
reciprocal action of the Cam Clutch outer race is
enlarged to 860°. In this machine, the 60 mm vinyl
sheet feeding length is indexed at a speed of 40 to 60
times per minute. In this case, the acceleration of the
Cam Clutch increases, a large torque acts repeatedly,
and the cam slipping distance at overrunning
becomes longer. Hence, a cam is required that has
superior engagement and higher anti-abrasive
properties. A brake is used in order to improve the
precision of the vinyl sheet feeding pitch.

• For medium speeds (up to 300 times/min.).
• Since a free-action type cam retainer is used, the
cam has excellent follow-up response at the time
of engagement.
• For low speed (up to 150 times/min.).
• No maintenance.
• For low speed (up to 150 times/min.).
• Since this series is mounted directly on the shaft,
it is possible to use a shaft of large diameter.
• For low speeds (up to 100 times/min.).
• Same dimensions as #62 bearing.
• For low speeds (up to 150 times/min.).
• Sleeve-type outer race enables mounting of
sprocket or gears as well as torque arms with
small boss diameter.
• For low speeds (up to 100 times/min.).
• For light loads, no maintenance.

MI-S
• The MI-S Series has been developed exclusively
for these applications.
• Special cam surface hardening treatment
improves the abrasion resistance.
• The shape and structure of the cam are specially
designed so that it can handle abrupt speed
changes (e.g. great acceleration) when engaging.
