Once driven shaft has been completely inserted into the unit’s keyed hollow bore,
secure the shaft in place using a keeper plate as shown to the left or some other means
of securing the unit to the driven shaft .
Do not operate unit until the torque arm has been attached .

Shrink Disc Type Mounting Introduction
The
keyless Shrink Disc
provides a reliable commodity shaft attachment for Sumitomo speed reducers and gearmotors . This system allows
bi-directional shaft rotation operation with a powerful, slip-free grip .
To assure peak performance of equipment, please read, understand and follow these installation instructions .
Do not
operate unit until the torque arm has been attached to the unit and fixed to a rigid structure . The torque arm prevents counter-
rotation during unit operation . Refer to Torque Arm Installation section in this manual for instructions .
CAUTION:
The Cyclo® BBB5 must be externally supported prior to insertion of driven shaft into hollow bore . External support
MUST be maintained until all shrink disc socket head cap screws have been tightened to the appropriate operational torque .
Bore and Shaft Tolerance Specifications
• Refer to the certified outline drawing or Cyclo® BBB5 Catalog for recommended machine shaft dimensions.
• Unless otherwise specified, the tolerance of the Shrink Disc Bore conforms to JIS H8.
• If application involves high shock loading and/or large radial loads, a shaft tolerance of JIS js6 or JIS k6 is recommended.
Shrink Disc Type Hollow Bore Installation onto Driven Shaft
Before placing unit onto driven shaft,
do not apply grease, oil, or anti-seize grease to the entire driven shaft or to the bore
of the shrink disc
. Use of these friction-minimizing products will adversely affect the ability of the unit to transmit torque .
1
Clean and degrease contact surfaces; reducer shaft and bore and the machine driven
shaft .
Apply Molykote 321 or an equivalent dry film lubricant to the driven shaft shoulder
opposite from the shrink disc .
Do Not
apply any friction minimizing compound to the driven shaft at or
near the shrink disc .
