Features of each series
| Type | Material | Features | |
|---|---|---|---|
| SS |
|
18-8SUS, SUS304 equivalent | Excellent corrosion resistance is made possible through the use of 18-8 stainless steel. Used immersed in water, in corrosive atmospheres produced by acids, alkalis, and other chemicals, and in high- and low-temperature environments. |
| HS |
|
Pins, bushes, and rollers are 13Cr stainless steel Plates are 18-8 stainless steel |
Longer life than SS specs, with 1.8 times the maximum allowable tension. Corrosion resistance is slightly lower than that of SS specs. |
| NEP |
|
Special coating and topcoat on RS roller chain | The strength of Standard Roller Chains along with environmental corrosion resistance such as salt water resistance, climate resistance, chemical resistance, etc. With no harmful chromium. RoHS compliant |
| NS |
|
18-12 stainless steel | Better corrosion resistance than SS specs. |
| LSK |
|
18-8SUS, SUS304 equivalent Bushes are a combination of 18-8SUS(SUS304 equivalent) stainless steel and special engineering plastic. |
Special engineering plastic is used for the bushes, realizing lubrication-free long life. |
| PC |
|
18-8 stainless steel used in outer plates and pins Engineering plastic (white) used in inner links |
Usable without lubrication, realizing lower noise and lighter weight. |
| PCSY |
|
Titanium alloy used in outer plates, pins, and fasteners Engineering plastic (matte white) used in inner links |
Better corrosion resistance than PC (Standard Series). |
| Titanium |
|
Titanium alloy | Non-magnetic, with superb corrosion resistance beyond the reach of stainless steel chains. |
| NP |
|
RS roller chain with nickel plating | In addition to the beautiful plated exterior, mild corrosion resistance enables use in environments exposed to water drops. |
| General-purpose | Alloy steel | Although this chain is not corrosion-resistant, it is high-strength steel. | |
In addition to the above, we have a variety of chains that can be used in a wide range of environments.
Details of each specification of the corrosion resistant chain can also be found on the product information page below.
Application examples of corrosion resistant chains by specification
Noodle production line
Reducing replacement frequency
Compared to conventional products
- Twice the wear life
- Maximum allowable tension 1.5x
Used on production lines where hygiene management is generally required, such as food machinery.
Heat treatment furnace
Reducing replacement frequency even in highly corrosive usage atmospheres
Corrosion resistance improved compared to SS specs
When the door of the heat treatment furnace is opened, the chain is exposed to the high-temperature corrosive gases within the furnace. The use of NS specs, with higher corrosion resistance than SS specs, realizes longer life.
Ice cream bar production line
Reducing position adjustment frequency
Compared to SS specs
- Better wear life (up to 3x )
- Maximum allowable tension 1.8x
Chain wear elongation led to position deviation in the ice cream production process, requiring painstaking adjustment.
The use of HS specs with excellent wear resistance reduced the adjustment frequency.
Yogurt filler
Reducing position adjustment frequency
Compared to SS specs
- Better wear life
- Usable lubrication-free
Ideal for applications where positioning accuracy is required in intermittent feeding, as with fillers. Initial elongation is small, with lubrication-free long life, reducing maintenance processes as well.
Rubber sheet production line
Reducing replacement frequency even in atmospheres exposed to water
Compared to Standard Roller Chains
- Same strength and wear resistance
- Improved corrosion resistance
Combines strength and corrosion resistance in high-humidity environments and corrosive environments such as those exposed to water drops.
Can direct conveyor
Does not damage conveyed objects
- Inner links are engineering plastic
- Usable lubrication-free
- Low Noise
The use of engineering plastic PC for the inner links enables low-noise conveyance which does not damage the objects conveyed.
Etching equipment
Reducing replacement frequency in strong-acid atmospheres
- Extremely high corrosion resistance
For the etching process, which uses acidic solvents, etc., extremely high corrosion resistance is required. The use of titanium chains sharply reduces the replacement frequency.
Sprockets Supporting Corrosion Resistant Chains
Sprockets used in special atmospheres are treated as special orders, including their technical feasibility, depending on client requirements.
