of the box dry. Use of color changing desiccant will aid in

identifying when desiccant should be changed.

Storage Period

tDo not store the unit for longer than 3 months without

following long-term storage procedures recommended by

Sumitomo.

t$POTVMU4VNJUPNPXIFOTUPSJOHUIFVOJUGPSNPSFUIBOmonths. Rust prooﬁng procedures are required.

t$POTVMU4VNJUPNPXIFOFYQPSUJOHUIFVOJU3VTUQSPPmOHprocedures may be required.

If the Cyclo® BBB4 gearbox will be inactive for a long period of

time, long-term storage preparation is required to prevent rust

or other degradation to the gearbox.

LONG-TERM STORAGE SPECIFIED WITH ORDER:

If long-term storage is speciﬁed at the time of order entry, Shell

VSI Circulating Oil #32 or NP-20 [JIS] equivalent rust preventative

is already sprayed into the Cyclo® BBB4 reducer and the air vent is

replaced with a sealing plug before shipping the reducer from

Sumitomo factory. External machined surfaces are coated with a

suitable NP-19 [JIS] petroleum base corrosion preventative such

as Black Bear Par-Al-Ketone, Houghton Rust Veto 342, Daphne

Ever Coat No.1 or equivalent.

Consult Sumitomo for Long Term Storage procedures:

t4UPSBHFXJUIPVUGBDUPSZQSFQBSBUJPOTt0OHPJOHNBJOUFOBODFEVSJOHTUPSBHFQFSJPEOperation After Storage

Before operating the unit after an extended storage period, ﬂush

unit of rust preventative and ensure that non-metal parts, i.e., oil

seals, o-rings, air breather, have not deteriorated. Non-metal parts

may deteriorate easily from exposure to ambient conditions (i.e.,

extreme temperatures, UV rays). Replace deteriorated parts with

new before unit start-up.

After starting the unit, verify that there is no abnormal noise,

vibration, and/or temperature rise. Immediately stop the unit and

call your local distributor, Original Equipment Manufacturer or

Sumitomo directly if you observe any abnormality.

Transporting

tDo not stand directly under a unit suspended by a

lifting mechanism. Injury or death may occur if the

unit is dropped.

tBefore lifting the unit, determine its weight (refer

to catalog, packing list, etc.) and ensure that the

moving equipment will support the unit’s weight.

tNever hoist or move a unit that exceeds the

moving equipment’s rated capacity or else

personal injury and/or equipment damage may

occur.

tDo not allow the unit to drop or fall while moving.

Always use the eye bolts attached to the gear

housing (and on motor if supplied) when moving

the unit. After securing the unit to the machine,

remove the moving hooks/straps from the

eyebolts.

Ambient Humidity: 85% or less

Ambient Conditions: 14°F minimum

Altitude: 3,280 feet (1,000 m) or less

Atmosphere: The location should not contain corrosive gas,

explosive gas, or steam. The location should be free

of dust and well ventilated.

Location: Indoor – free of dust and water

Consult Sumitomo when the unit will operate in conditions other

than those speciﬁed above. Special unit modiﬁcations may be

required.

Units manufactured according to customer speciﬁed application

requirements (i.e. outdoor modiﬁcations, high-temperature

modiﬁcations) are designed to operate within the speciﬁed

environment.

Install the unit so inspection and/or maintenance procedures may

be easily performed. Install all units that are not shaft mounted

on a suﬃciently rigid base.

Torque arm clearance with machine structure is required to allow

for machine shaft run out. Refer to the Torque Arm Installation

section in this manual for additional information.

Installation Angle

Mount the unit in the speciﬁed position for which it was

ordered. Conﬁrm the mounting position from the gearbox

nameplate.

Consult your local distributor, Original Equipment Manufacturer

or Sumitomo directly if the mounting angle is to be other than

horizontal or vertical.

Severe Loading Conditions

For applications with severe vibration and/or frequent starts and

stops, Sumitomo recommends the use of high-strength mounting

bolts of Grade 8.8 (or greater).

Cyclo® BBB4

Installation onto Driven Shaft

Taper-Grip® Bushing

Taper-Grip® Bushing Introduction

The keylessTaper-Grip® bushing system provides a simple and reliable 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 your

equipment, please read, understand and follow these installation instructions.

Prior to installation of the Cyclo® BBB4 onto the driven shaft, ensure that

the shaft length meets or exceeds the minimum shaft engagement value

“TT” detailed in Table 1.

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® BBB4 must be externally supported prior to

insertion of driven shaft into bushing. External support MUST be

maintained until all bushing socket head cap screws have been

tightened to the appropriate operational torque.

Components of Taper-Grip® Bushing

As shown in the ﬁgure on the left, the Taper-Grip® bushing includes the bushing,

thrust collar, and socket head cap screws.
