Roller chain

Tensile strength: The maximum load when the chain is pulled to the point of breaking.
Average Tensile Strength: the average value of tensile test results
Minimum Tensile Strength: The setting value from calculation in consideration of the dispersion in the quality of components based on Average Tensile Strength.
Maximum Allowable Load: The allowable limit of maximum load based in dynamic strength.

Conveyor chain

Tensile strength: The maximum load when the chain is pulled to the point of breaking.
Average Tensile Strength: The setting value from calculation of tensile strength by engineering design.
Assured Tensile Strength: The tensile strength that the manufacturer guarantees in transactions with the market in general, or with a specific user. It is generally set according to the minimum tensile strength, but may be determined in other ways in other circumstances.

The maximum allowable chain tension when using offset links on roller chain decreases as shown below.

There are two points crucial to the lubrication of roller chain, as indicated by numbers 1 and 2 in the diagram.

(1) Lubrication between pins and bushings Lubrication at this point prevents friction between pins and bushings, which are the main cause of roller chain wear.

(2) Lubrication at this point prevents friction between bushings and rollers, reduces noise, and absorbs impact load.

CLOSE

In general, use a high-grade industrial lubricant. Select a lubricant with appropriate viscosity according to the ambient temperature, lubrication type, and chain size from the table below.

Roller chains

Do not use waste oil as it may contain foreign matter, dust, or chips, or heavy oil or grease as they have a high viscosity and cannot penetrate the area between the pin and the bushing smoothly.

Lubrication Category A: Frequent manual lubrication with an oilcan or a brush
Lubrication Category B: Drip lubrication
Lubrication Category C: Oil bath or disc lubrication
Lubrication Category D: Pressure-fed lubrication with a filter, an oil cooler attached if necessary

Commercial lubricating Oil (for reference)

Special lubricating oil is required when the ambient temperature is below 0°C or above 50°C. Also, depending on the usage environment, lubrication may not be possible.
In such cases, please contact us.

Conveyor chain comprises components such as link plates, pins, bushes and rollers. The example below is a standard conveyor chain.

We deal in a variety of standards, including JIS (Japanese Industrial Standards), ANSI (American National Standards Institute), and ISO (International Standards Organization).

The difference is the outer diameter of the rollers used. The S-roller type uses smaller rollers, while the R-roller type uses larger rollers.

Small roller series (S-roller type)

• The last digit in the chain’s numeric designation will be 0.
• This series has the same roller diameter (outer) as standard roller chain.
• Standard sprockets can be used if they have 30 or more teeth.

Large roller series (R-roller type)

• The last digit in the chain’s numeric designation will be 2.
• This series has the same roller diameter (outer) as double-pitch roller chain.
• Specific sprockets must be used.
