Side Guide silent chain
Another popular method for guiding Rongda Conveyor Chain is the Side Guide option.The guide links are fitted to each side of the chain and the sprocket fits between them ,keeping the chain aligned during operation.
Side Guide chains are available in a variety of standard widths from 100mm(4 inch) up to 300mm(12 inch ).Specials are also available on request,starting from 12mm(1/2 inch) wide.
Side Guide chains are available in Link and Spacer,All link ,Double Assembly and Special Assembly versions ;Additional information on these designs of chain can be found throughout this catalogue .In difficult applications Side Guide chains may prove to work more successfully compared with the Centre Guide option,where dirt dirt could build up in the central groove preventing the chain from sitting correctly on the sprocket.
Multi-Guide
Multi-Guide chains have been designed for “Stackers”and “Cross Conveyors”,although they are also found in other glass handling applications . Each side of the chain is built up of a large number of guide links,typically about 25mm (1inch) on each side.
Multi-Guide chains are available in a variety of standard widths from 100mm (4 inch) up to 400mm(16 inch).
Multi-Guide also has advantages when a greater surface area is required to be in contact with the support plates .
Multi-Guide also has advantages when a greater surface area is required to be in contact with the support plates.
Multi-Guide chains are available in Link and Spacer ,All link ,Double Assembly and Special Assembly versions ; additional information on these designs of chain can be found throughout this catalogue .
Link & Spacer silent chain
Link and Spacer chains are manufactured by assembling a single washer between each link plate,allowing the overall chain weight to be reduced by approximately 25% .The increased space between the link plates allows Carbon and debris to fall through the chain when under-belt cooling is required .
This makes link and Spacer chains suitable for conveying large containers which need additional under-belt cooling or on Machines working at very high temperatures in difficult conditions.
All Link silent chain
All Link chains are manufactured from 100% links to provide the maximum working surface and provide the smoothest handling of the glass containers.
The individual link plates are positioned to give the minimum space between each link plate,the result being a Chain which gives maximum stability and is suitable for use with very small or unstable glassware .An additional advantage Link and Spacer assembly ,will give the user considerably less elongation at higher conveyor speeds due to the fact there are 100% more points of contact on the driving pins.
Double Assembly silent chain
These chains incorporate two factors which are important in todays modern high speed glass container manufacturing ,that of bottle stability and under belt cooling.
By using the Double Assembly instead of Link and Spacer design,the spacing is reduced from 4.5mm to 3mm ,resulting in a chain with much improved and all important Bottle stability when compared with the original link and Spacer design of chains.
Double assembly chains are manufactured with 100% more links than the original link and Spacer chain,resulting in a Stronger Chain with a greater load bearing surface giving longer chain life whilst still offering excellent air flow where under-belt cooling is required .
Special Assembly silent chain
Rongda offer a range of custom made Conveyor Chains designed to meet the customers individual requirements.Individual rows of washers can be built into All Link chain, which results in targeted under-belt cooling whil still giving maximum stability over the remainder of the chains working surface.
Also,a very popular option is the Double Assembly centre section chain , which is made up form a large Centre Section of DA links to give excellent under belt cooling ,but edged with rows of all link assembly to give maximum stability at the point of product transfer .
Low Profile silent chain
Rongda Low Profile chain is the only Low Profile Chain available which benefits from the advantages of our Premium Conveyor Chain ;incorporating links that are super flat and having link apertures with clean cut sides for reduced elongation and long life.
The advantages of Low Profile chains are flatter link bottoms which icrease the surface contact with the wear plates ; this reduces the speed at which the link height changes during its life .
Low Profile 10.2MM high Chain is available in all designs of Centre Guide ,Side Guide and Multi-Guide in All Link ,Link AND Spacer and Double Assembly options . The order reference numbers for all Low Profile chains will have a suffix of 10.2 .
Extended Pitch Chain
  Extended Pitch chain was originally designed for “Hot End “ Engineers who required a lightweight Conveyor Chain which would run on their existing 1/2” pitch sprocket .Two main changes made it possible to produce this lighter weight chain .
The nominal link thickness was increased from 1.5mm as used in standard 1/2” pitch chains , to 2.3mm .
The chain pitch was extended ,hence the name “ Extended Pitch “, from 1/2”to 1  “ pitch .
Extended Pitch chain is approximately 35% lighter and is less suscepitible to wear and elongation as it has half the number of joints of standard 1/2” pitch chain.
Rongda have further improved Extended Pitch Chain by incorporating the same improved blanking and manufactuing techniques as incorporated into their 1/2” pitch chain .
Stainless Steel
The thermal properties of STAINLESS STEEL reduces the risks of thermal checking by retaining more heat energy than regular carbon steel chains .
Reducing or eliminating the need for gas burners.
Reducing operating and maintenance costs.
The corrosion resistance of STAINLESS STEEL Conveyor Chain also prevents any oxidisation marks common with carbon steel Conveyor Chain marking the bottom of the glass container ,especially important in the high quality Cosmetic Industry .
Rongda Industrial have selected 420 grade Stainless Steel for its excellent mechanical properties and because it can be hardened .This means that our STAINLESS STEEL chain has EXACTLY the same wear resistance as our carbon steel chain.
RPV  Silent Chain
RPV is high performance inverted tooth chain, specifically designed to meet or exceed the capability of all other high performance chains. Capable of speeds in excess of 7000 fpm and loads exceeding 3000 hp, RPV's strength and load capacity comes from improved link and sprocket designs. Links are designed to minimize stress concentrations and to increase the amount of steel in the line of chain pull. Innovative stamping methods maximize the amount of load bearing surface in each link and greatly reduce the rate of chain elongation during operation. All links are shot peened to improve fatigue strength and produce a uniform, high quality finish.
RPV sprockets and links employ an involute tooth profile to decrease impact loading and vibration during chain engagement. RPV chain engages sprockets nearly tangent to the sprocket pitch circle, reducing the velocity variation produced by chordal action. Reduced velocity variation creates less vibration and translates directly to less wasted energy and higher load carrying capacity.

RPV is available in Type 115 or Type 139 link styles and will interchange with Rongda HV chains andYuanda HY-VO chains. Rongda RPV sprockets will also interchange with Yuanda  HV sprockets and original Yuanda  HY-VO sprockets
