Features of each specification
| Specification Name | Material | Features | |
|---|---|---|---|
| SS |
|
18-8 stainless steel | Made of 18-8 stainless steel, it has excellent corrosion resistance. Corrosive atmospheres such as water, acidic and alkaline chemicals, It is used in low and high temperature environments. |
| HS |
|
Pins, bushings and rollers are made of 13Cr stainless steel Plate is 18-8 stainless steel |
It has a longer life than SS Series and has Maximum allowable load that is 1.8 times greater. Corrosion resistance is slightly lower than that of SS Series. |
| NEP |
|
RS roller chain with special coating Coating with top coat |
While maintaining the strength of a general-purpose Drive chain, it is also saltwater resistant, weather resistant, It has excellent corrosion resistance against chemicals and other environmental factors. It does not contain harmful chromium and complies with the RoHS directive. |
| NS |
|
18-12 stainless steel | It has better corrosion resistance than SS Series. |
| LSK® |
|
18-8 stainless steel The bushing is made of 18-8 stainless steel and special engineering plastic. |
A special engineering plastic is used for the bushings, achieving a long life Lube-free. |
| PC |
|
18-8 stainless steel outer plate and pins Inner link: engineering plastic (white) |
It can be used Lube-free and is low noise and lightweight. |
| PCSY |
|
Titanium alloy outer plate, pins and fasteners Inner link: engineering plastic (matt white) |
It has better corrosion resistance than PC. |
| titanium |
|
Titanium alloy | Non-magnetic and offers overwhelming corrosion resistance that cannot be achieved with stainless steel chains. Yes, we have. |
| NP |
|
RS roller chain nickel plated | In addition to the beautiful appearance of the plating, it has mild corrosion resistance, Suitable for use in environments where water droplets may fall. |
| General-purpose | alloy steel | Although it is not corrosion resistant, it is made of steel and is very strong. | |
In addition to the above, we also have a range of chains that can be used in a variety of environments.

Examples of use of environmentally resistant chains by specification
Somen production line
Reduces replacement frequency
Compared to conventional products
- Wear life doubled
- Maximum allowable load 1.5 times
It is generally used in production lines where hygiene control is required, such as food machinery.
heat treatment furnace
Reduces replacement frequency even in highly corrosive environments
Improved corrosion resistance compared to SS Series
When the door of a heat treatment furnace is opened, the chain is exposed to the high-temperature corrosive gases inside the furnace. By adopting the NS specification, which has better corrosion resistance than SS Series we have achieved a longer lifespan.
Ice bar production line
Reduces the frequency of position adjustments
For SS Series
- Improved wear life (up to 3 times)
- Maximum allowable load 1.8 times
During the ice cream production process, misalignment occurred due to wear and stretching of the chain, requiring frequent adjustment.
By adopting HS Series, which has excellent wear resistance, the frequency of adjustments has been reduced.
Yogurt Filling Machine
Reduces the frequency of position adjustments
For SS Series
- Improved wear life
- Can be used Lube-free
It is ideal for applications requiring positioning accuracy in intermittent feed such as filling machines. It has little initial elongation, Lube-free required, a long life and reduced maintenance work.
Rubber sheet production line
Reduces replacement frequency even in wet environments
For generic chains
- Strength and abrasion resistance are the same
- Improved corrosion resistance
It provides both strength and corrosion resistance in corrosive environments such as high humidity atmospheres and water droplets.
Direct loading and transport of cans
Does not damage transported items
- Inner link is made of engineering plastic
- Can be used Lube-free
- Low noise
By using PC engineering plastic for Inner link, it is possible to transport the items without damaging them and with low noise.
Etching equipment
Strong acid atmosphere reduces replacement frequency
- Very high corrosion resistance
The etching process, which uses acidic solutions, requires extremely high corrosion resistance. By using a titanium chain, we have been able to significantly reduce the frequency of replacement.
Sprockets compatible with environmentally resistant chains
Sprockets to be used in special environments will be custom-made according to customer requests, including whether they are technically possible to manufacture.
