Straight Side Plate Chain
Ò¶ÒèI_ýÞSK
This chain is based on ANSI standard roller chain but outer plates are the
same as inner plates in straight form, thickness and height. It has greater
fatigue strength performance than standard roller chain and can also be
used for a conveyor

The Heavy Series Roller (H) Chain has increased thickness of the
roller link plate and the pin link plate than the Standard Roller
Chain. Accordingly, it has enhanced ultimate tensile strength and
allowable load by about 10%. By specially processing pin holes of
the pin link plate, we improved minimized chain extension.

Dong Bo Leaf chains consist of only simple Link plates held
together by riveted pins for a high strength linkage. Combined
with their greater tensile strength and directional flexibility, they
find excellent applications, such as balance or counterweight, lift
truck, fork lifts and other lifting machinery, which more at low
speed.

The general wear resistant conveyor chain is produced from the
quenched & tempered Heat-Treatment to alloy steel of
materials. This Wear-Resistant Bucket Elevator Chain is
produced by combination of selected materials and technology
through our lots of experiment. In this point, chain parts of Pin,
Bush Roller, are ultimately designed with considering
dimensions, clearance & hardness. This specially designed
chain can guarantee improved life by 2times than general
Wear-Resistant Conveyor Chain.

Bearing Roller Chains
ì ¯BrbSK
Ball bearing chain ì ¯BSK
This chain contains ball bearings inside the rollers.
Low rotating frictional force of the roller allows minimal operational
loss and high allowable load compared to other rollers.
hDimensions of the assembled chain and
attachments are identical to general conveyor chains.
hGeneral conveyor chain sprockets are used.
hCoefficient of rotating friction f : 0.035~0.05

This is a horizontal Scraper (within 10° gradient, adjustable upward
or downward) Chain for conveying grains.
Purpose of the scratch plate is to prevent conveyed items from
breaking, and the cleaner prevents conveyed items from remaining
in the case.

Case Conveyor Chain
¾I ¶ìI ¯SK
The case conveyor rotates a chain inside a casing with square
sections.
The chain has the most logical shape according to the type of the
conveyor and the characteristics of conveyed items. There are T
and U-types and special UA, UB and UC-types. This chain
maintains sufficient strength through our unique heat processing
technique, is light, has high density, and is adequate for harsh
conditions.

Material of top roller (No code: steel, P: plastic)
The Top Roller chain places items on top of continuously running top
roller of the chain and they can be freely conveyed regardless of direction
or speed. You can choose steel or plastic resin as a roller's material
according to applications.
-Advantages of Steel Roller Type: higher max. allowable Load and
approval working temperature (-10_150)
- Advantages of Plastic Resin Roller Type : light weight, less noise

Double Plus Chains
ÓØSK
Double Plus Chain (also called Triple Speed chains) are used typically on
accumulating assembly line conveyors. This chain's two rollers rotate
identically according to the frictional force between the large and small
rollers. Items are conveyed about 2.5 times faster than the speed of the
chain (the chain speed according to the ratio of the roller's outer diameter) In
addition, when braking forces are applied, slip occurs between the large and
small rollers, making the chain to be conveyed freely. Double Plus Chain
are available with 'snap covers' to keep particles out, in resin rollers and with
protective coatings (nickel, chromium plating).

Dong Bo's lube-free chain NOS combines a special oil-
impregnated sintered Bushing and coated pin for long-term
internal lubrication.
The advantages of the Dong Bo Lube-Free chain [NOS]
!ŸUp to 40 times longer service life in comparison with standard
roller chains without lubrication in low operating speed 30m/min
and up to 10 times longer service life in normal speed 90m/min.
!ŸNo further lubrication required
!ŸClean application, no soiling of machinery and transported
goods
!ŸFit for standard sprocket
!ŸThe same breaking load at Dong Bo standard Roller chain’s.

Environment Resistant Chains
r 'r ÌSK
1. Stainless Steel Chain Series *Kè pSK
The chain is ideal for acidic or alkaline environments, or where
the chain will be exposed to water and for very high or low
temperature locations, where resistance to corrosion is
required.
Dong Bo Chain offers either SS 300 Series(austenitic
stainless) or SS 400 Series (martensitic stainless).

<Features>
* Wide range of stainless steel attachments
* improved maximum allowable load
* A Stainless Steel chain is the highest in corrosion resistance
and heat resistance, and can be used in all chemical plants,
food processing machines, water treatment machines, etc.
* Can be used in corrosive chemicals, acids and alkalis, tap
water, salt Water and in high levels of moisture
* High and low temperature capability
(approval working temperature: -20~400)
* Rustless
* Minimized weight
* Attention: After cold working, chain can be a little magnetic.

Result from nickel plated surface, this chain can be used under
outdoors, acid vapor or salty environment. Nickel plating delays
the corrosive effect on the chain.
But in general, nickel plating is specified when appearance of
chain is critical, for the cost is less than comparable stainless
steel chains. Nickel-plated chain offers acceptable protection
for mildly corrosive environments. For more corrosive
environments, please consider stainless steel chains.

The Side Bow Chain has special flexibility allowance
between pin and bush, and between the roller link plate
and the pin link plate. This gives additional radius for
curving sideways and basic dimensions are identical to
Standard Roller Chains. By applying various attachments
to the chain, it can also act as a precision conveyor
chain.

Marine Diesel Engine Chains
¶Å @$ ÂÓSK
The Marine Diesel Engine Chain is attached to engines of various
types of vessels and rotates the camshaft axis. It is manufactured
with high durability, fatigue resistance, and strength. The Marine
Diesel Engine Chain, all over the world, including Dong Boss
products, conforms to the British Standard. Dong Bo chain has
acquired certicate for the chain by MAN Diesel & Turbo, the 4th
chain brand in the world.

This chain is generally selected and applied proportional to the
motorcycle displacement, and the chain number is internationally
compatible. Required enormous force for high-speed rotations, the
chain is forced to withstand from impact, abrasion, and fatigue.
Therefore the chain is also widely used in various power transmission
equipment of farm machine, general machinery fordyeing wearing,
etc.

The O-ring Chain is designed by inserting o-rings
between the roller link plate and the pin link plate of
motorcycle’ drive chains to prevent protect the
components from friction, heat generation and foreign
substance penetration between the roller link plate and
the pin link plate which are rotate at high-speeds. This
chain is adequate for motorcycles with large
displacements.

Dong Bo Pin Oven Chain is specially designed for can painting
and labeling conveyor lines. The chain can withstand in high
operating temperature (available in 250) and at high speed
(250m/min = an output capacity of 1,800~ 2,000 cans perminute).

Trolley Chain (Overhead Type)
_;SK
Trolley conveyor allows for maximum conveying flexibility in small
spaces, because they can use the space three dimensionally.
Dong Bo produce various range of trolly chains for this conveyor
system.
Typical applications for our trolley chains include:
- Assembly lines : in Automobile and electronic industries.
- Conveying lines: Tyre, steel, textile, sanitary goods, etc.
- Painting, plating and drying lines in all industries.
Dong Bo trolley chain with high-precision built-in vertical bearings
has outstanding stability, making much less noise than other
brands and the chain can be custom-configured to any
requirement. Our trolley chains are used in most modern
automobile factories world wide.

All components are manufactured with carefully selected stainless steel
through the precision press procedure.
This chain is designed with high precision and has light weight. It maintains
sufficient ultimate tensile strength and has excellent capabilities to
withstand from corrosion and abrasion.
SF-4 attachments are placed on Sludge Collector Flights, D-22
attachments on Grit Collector Bucket Elevators, and A-2 attachments on
Dust Collector Rakes.
