The type of materials you'll require your chain to be made from comes down to several factors such as heat, load, noise as well as the conditions in the working environment. If you're still unsure as to the right choice, we would recommend talking to a specialist
Considerations when choosing a chain
There are a few key factors to consider when choosing a roller chain, most of this boils down to technicalities and mechanical specifications.
**Tensile strength** - This is the tension load at which the chain will fail.
**Maximum allowable load** - The tension rating for which the chain will carry when running. It is in the interest of safety that this is not exceeded.
**Chain weight**- The weight of the chain per unit, this varies with pitch and materials used etc.
As always taking stock of the environmental conditions is a consideration as moisture can cause corrosion and excessive heat can cause metal to expand.
## Understanding roller chain standards
British Standard / DIN / International Standards Organization (ISO) are governed by European standards committees. The standards that govern and categorise roller chains is ISO Standard 606 the number relates to the chains pitch in 1/16" increments, these are shown in millimetres.
How do I lubricate a roller chain?
Like all moving parts making sure that your roller chain is well lubricated will not only keep it running smoothly, but will also help protect it from wear and tear caused by use as well as providing protection against corrosion. Chains can be lubricated in various ways including manual brushing, spray application, drip and oil baths. As with any lubrication application, ensure that the right type of lubricant is used, this will help improve the lifespan of the chain.
What are the main parts of a roller chain?
Roller chains are all constructed in much the same way. They consist of a pin, bushing, roller, pin link plate and roller link plate.
